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!!!
