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!!!!!

Tuesday and Friday combo!!!

TUESDAY: It was tough toremember but we did a lab on the different kinds of structures: Homologous, vestigial, and analogous structures.

FRIDAY: Ok I know what happened on friday. We took a lot of notes on Genetic variation, Genetic drift, what defines a species, speciation, adaptive radiation, convergent evolution, coevolution, and relative and radioactive dating oooo la la.

The homework from friday was to read 19.1, finish UP 33-36

I dont know who needs to scribe so i will pick on monday, ooooooo a mystery oooooooohhhh

It's the weekend

On Friday we learned about Fertilization and Implantation. We took notes and discussed this in class. Then we had about 30 minutes to work on lab 31. The notes were:

-Fertilization occurs in the oviduct

-Zygote-a fertilized egg, diploid cell

-Cell division begins

-embryo-more than 1 cell

-morula-solid ball of 64 cells

-Blastocyst-hollow ball of cells

-Embryonic Development

-gastrulation is the formation of 3 embyronic germ layers

-endoderm -lining of digestive, reproductive, and respiratory systems

-mesoderm- muscles, blood and bones

-ectoderm- skin and nervous system



The homework for the weekend was to do pages 19 and 20 in the U.P. and to read 34.4 and do a flow map



Have a good weekend, the next scribe is Briget N!!!

Pokemon Transcription

Today en la clase Mrs. Stien collected our flow chart HW and gave us three pictures for notes. We watched an animation of transcription We took notes on transcription and translation. Here are the notes:

TRANSCRIPTION= (RNA Synthesis) One strand of DNA serves as a template for the synthesis or mRNA (DNA: TACCAGGTT)-----(mRNA: AUGGUGGAA)

this thing a ma giger right hereee^ is the trancribe

Occurs in the Nulceus

RNA plumerase joins RNA nuleotides

______________________________________________________________________

TRANSLATION=

mRNA- 3 codon (AUG)

tRNA- 3 anticodon (UAC)

Example of start codon- AUG

>>> 3 types of each.

Example of stop codon- UAA

mRNA attaches to a ribosome

Each tRNA carries 1 A.A.

Anticodon on tRNA matches with a codon on mRNA

A.A. bond together forming a polypeptidee chain.

Long polypeptide chains make a...... You guessed it PROTIEN!!!
