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!!!
