Pictures! Pictures! Pictures!

hey hey hey!!
I found dome really cool pictures of plants at my house and one of them is actually a good example of phototropism! ( at first me and my sister thought that my cat broke it but then we were realized that the roots were still deep in the soil)
I can't name most of them except one of them is a jasmine also known as a raat ki rani which means queen of the night. it's called that because it blooms at night! it's most common name is in hindi because it's prominent is south asia and it's berries are poisonous!!!!

I'm not sure what plant this is

same with this one but it's pretty awesome

this is the example of phototropism! notice how since the blinds are semi up its growing up and to the side to get light energy. you can't see the second window too well but the start of where the blinds finish is just cut off.

Jasmine or "raat ki rani" i haven't seen this one bloom in a really long time but it usually blooms in the summer and it makes the whole room smell amazing!!!

this is what the flower looks like. I honestly was not aware of the words at the bottom but they made me lol just a little bit :)

Spring Break Soon!!!!

Homework:
-U.P. 45-46 due tomorrow
-read textbook pages pg. 704-705 only
presentations tomorrow--make sure you get your project handed in by 8AM tomorrow!
wierd plant quiz-Thursday
PLANT TEXT FRIDAY!!

Today we started class by getting our Plant of the Day--->String of Pearls- it looked like peas!

We also talked about how for the presentations you should be animated, project your voice, and engage the class!!! and you will get a good presentation grade.

NOTES:

Pollination:
*pollen transfers from anther to stigma
--self-pollination: pollen fertilizes ovule of same plant
--cross-pollination:pollen fertilizes ovules of another plant
*Increase genetic variation

Fertilization
1. Pollen lands on stigma
2.Pollen tube grows in the style
3.Sperm and egg form a zygote

Double Fertilization
*2 sperm enter the ovary
*1st sperm fertilizes the egg; results in a zygote (2N)
*2nd sperm fertilizes in the polar nuclei forms endosperm (3N)

Cross Pollination Methods
*Wind Pollination
-Inefficient, high pollen production
-Flower are smalls and not not colorful
*Vector Pollination
-more efficient
-Plants attract pollinators by...
-color
-fragrance
-nectar

Coevolution
*Two species evolve in response to changes in one another

Seed Disperal
*Wind
-Maple trees, dandelions
*Barbs stick to animal fur
-Buraock plant
*Animals eat and excrete seeds


Next Scribe is.......Sabina!!!!!!!!!!!!!!!!

IM SORRY THIS IS SO LATE!!!!!!!!



homework for the week:

• UP41-44 and the lab quiz TOMORROW


• read 704-705 ONLY!!!!!! with UP 45-46 WEDNESDAY


• Wierd plants quiz-know why the plant is wierd THURSDAY


• STUDY FOR THE PLANT EXAM ON FRIDAY!!!!!!!!!!!!!!!!!!!!!!!!!!!

today in class we started as usual. we walked inside and joked about the plant of the day and then got class started. We started class by going over the transpiration lab that was due today. Then Mrs. S went over any questions that anyone had on flowers from our text book reading that was also due today. After all of that we handed in the transpirstion lab and our flower diagram got a beautiful stamp on our stamp sheets=). When all of the mumble jumble stuff finished we broke up into our lab groups and completed the flower lab where we disected a flower! They are pretty cool! The flower lab can be found on UP pages 41-44, that is due TOMORROW in class. Good luck to everyone on the lab quiz tomorrow even though Mrs. S showed us the quiz it didn't help much;)

Scribe for tomorrow is

duh duh duh duh WOSSY!!!!!!!=)

hey guys!

hello everyone. we started off our day with mrs. stein collecting our homework and giving us a stamp. After that we did our weird plant of the day. The weird plant of the day was THE MADAGASCAR PLANT!!!! this plant was pretty crazy. It looked like a palm tree except it was quite spikey. I should know this better than anyone because I decided to grasp the entire plant and it cut me in like 4 different places. Ok so after we checked out the plant we started a little lab. The lab was kind of virtual. We never actually did anything but we had the information we needed. Ok so the lab was to see how much water was lost if we put a plant in 3 different environments and seeing how much water came out of the plants in each of the environments. The 3 environments were bright light, wind, and mist. There was also a normal contol group. The act of water coming out of the plant is called transcription. and there was the least amount of transcription when the plant was in the moist environment and the most amount in the wind environment! Ok my children!

THE HOMEWORK IS TO FINISH UP THIS LAB AND UP 39 (~_~)

What a lab!

MOSSY BALLS!!!!!!!

Today's plant of the day was a moss ball. The moss ball is actually made of algae, so don't let its name confuse you

In class we...
-Reviewed the vascular system
-Took a quiz on photosynthesis
-Started our homework, which was to read pages 669-671 & 674-677 and to complete a double bouble map comparing stems and roots.


Don't forget that our national park presentations are due next week, so get cracking on those power points.

Here are some pictures of plants and photosynthesis because I don't know what else to scribe about.






















The next scribe will be DAVID!!!!!

Data for Factors Influencing Photosynthesis

Another day at science

HW- u.p. pages 73-76

and continue the

plant project.

-today in class we reviewed the homework from a few days ago, which was pages 81-85.

-We reviewed all the things we previously knew about photosynthesis and the structure of a chloroplast

-In photosynthesis there is a light dependent and light independent cycle

the light dependent cycle takes in sunlight and water.

When the water is split to form ATP oxygen is released.

-Once enough ATP and NADPH are created they go on to the light independent cycle, or the calvin cycle. In this cycle the energy from the ATP and NADPH is released and combine with other things, like carbon dioxide, to form glucose.

PiGmEnT LaB!!

hey guys soo sorry!haven't really been home but this is what we did in class on thursday, since we were just in the imc on friday.

we started off with taking some notes and learning a

little bit about pigments and light and

photosynthesis.

Light and pigments

-light travels in waves

-different colors have different wavelengths

-white light is a mixture of all colors in the visible spectrum

-a red wavelength is the longest and least energy

-purple wavelength is the shortest and most energy

-plant pigments absorb sunlight

-chlorophyll is the green pigment neede

d for photosynthesis

Photosynthesis

-the reactants are CO2, H2O, light energy

-the products are O2, C6H12O6(glucose)

-TWO reactions:

-Light reaction

-Calvin Cycle(light independent reaction)

Chloroplast structure

-Thylakoid- sacs contain chlorophyll

-Granum- stacks of thylakoids

-light reaction

-Stroma- open space

-Calvin cycle

Next in class we did a lab on UP pages 69-72 about pigments in plants. We rubbed the pigments from two different leaves of plants(spinach and red leaf) onto a piece of filter paper and let it sit in a beaker with 70% isopropyl alcohol for about 15 minutes. After the 15 minutes we observed the paper and the d

ifferent colors that showed up on the paper represented the pigments in the leaves. Here is the key for the types of pigments:

COLOR PIGMENT

Red anthocyanin

Faint Yellow carotenes

Bright Yellow xanthophyll

Yellow green chlorophyll b

Green chlorophyll a

The data my group collected was the spinach leaf had chlorophyll b, chlorophyll a, carotenes, xanthophyll in it, and the red leaf had all of those and also anthocyanin. Here are some pictures of the lab we did.

The homework for thursday night was read 8.2 and 8.3 and do either UP pages 81-85 or a reading strategy of your choice, and also finish the pigment lab and research for your national park(march 23). The homework for the weekend is to read 643 and 664-666. There is no reading strategy but we will need to know this because Ms. Stein will not be lecturing on this. I hope everyone had a great weekend!! :)

The next scribe will be.. Neal!

Wednesday...wow it feels like a tuesday!

"Plantlets"
Spider Plant at my house :)



We started the class by turning in the plant lab which was due today. We then talked about the AMAZING plant of the day, which was the SPIDER PLANT! An interesting thing about the spider plant, is that it can self-propagate. This means that it can produce a baby plant of itself that roots in the soil. "Plantlets" are spider babies that the plant produces. It is a common houseplant that produces white flowers. After we finished talking about the plant of the day, Mrs. Stein demonstrated with the class Venus fly trap of how it closes to catch prey. She stuck a metal object inside an open trap and it closed up. It was pretty cooolll!!

Then we had a discussion about energy by answering a worksheet with our lab groups. Afterwards, talked about the questions as a class and Mrs. Stein elaborated on them.
Some of the questions were: (in up page 61)

Q:What is energy? Describe some characteristics of energy.
A: It is the ability to do work and it cannot be created or destroyed. It is TRANSFORMED!

Q: What is energy used for in living things?
A: to live and carry out functions

Q: What contains energy?
A: light, electric, sun, heat, chemicals

Note: When we consume food, we are consuming chemical energy which is stored in electrons of chemical bonds. In our body, our mitochondria is producing ATP.

Q: Why should you wear a white shirt on a hot day, not a dark shirt?
A: Dark colors absorb more heat or wave lengths of light and a white shirt reflects all wave lengths of light.

Q: What do you know about photosynthesis?
A: It is the process by which plants convert light energy into chemical energy. The energy is stored in bonds of carbohydrates and plants make glucose by using photosynthesis.

Q: Describe the structures of a leaf that allow it to carry out the function of photosynthesis.
A: The shape of the leaf, being flat, increases SURFACE AREA which allows maximum light absorption. The cuticle prevents water from evaporating and the palisade layer is compacted with many chloroplasts. It is towards the top which allows maximum light absorption.

We talked about now light travels in waves and how colors have different wave lengths. "White" light is a mixture of all colors in the visible spectrum and plant pigments absorb sunlight. Chlorophyll has green pigments which is needed for photosynthesis. It reflects mostly green and it absorbs most all other colors.

We also reviewed Mrs. Stein's blog because SAM did not blog...so look at her post from last night.

HOMEWORK:
1. Read section 8.2 and 8.2 with UP pages 81-85 OR a reading strategy of your choice that fits reading-DUE FRIDAY!
2. Work on plant national park project
3. up pages 67-68

THE NEXT SCRIBE IS.....MADISON!

First day of Plants!!!

Hello fellow class mates! Here is my blog post.
Ok so when we first walked in we got an excited welcome from mrs stein! She was very excited because we are now moving into the plant unit. We received a large yellow packet. So if you did not get one yesterday it is a good idea to pick one up asap. We started class off with the first plant of the day! This plant was... The baseball plant!! It is a round succulent plant. Very interesting stuff! All the plants we learn about will b on the test so keep the sheet!! Next we took plenty of fun notes on plants, and how they evolved. That was a good time.... But! We moved on to the most exciting part of the day. The lab. It is pages 5-7 that was also hw along with page 19. In this lab we went around and looked at different plants. It was our job to take our best guess at what type of plant it was. The choices were fruit, stem, root, leaf, or flower. It was a pretty difficult choice for some plants but overall a very interesting and fun lab! Well that was my blog! I hope u enjoy it and I'm glad I do not have stand in the corner holding paper with my nose. Peace!

Our next scribe will be... NEAL
