Today I learnt about stem cells and that when cells are Pluripotent it means that the cells can form and become anything, also that all humans have stem cells, but they are a little different compared to animals. and lastly I learnt that Embryonic stem cells are derived from the embryo in the early stages of development.
This is the development of the Monarch butterfly, also known as Danaus Plexipus. It goes through metamorphosis, starting out as larvae feeding off of milkweed, and then it goes into the cocoon stage with a hard case like shell to protect it during development. And lastly the cocoon known as the chrysalis breaks open and out comes the adult butterfly.
I learnt about identifying the development, phylum, and descriptions of animals and insects that were preserved in the Phyla blocks.
I grouped the animals and insects into certain groups for example:
-sea star
-sand dollar
-sea cucumber
-sea urchin
-brittle star
These are all grouped into a group called "Echinoderm Comparison"
All of the above belonged to the phylum Echinodermata, were symmetric and live in water.
I also leart how frogs go through Metamorphosis starting out as a egg---tadpole---2 leg---4 leg--adult, and that they belong to the phylum chordata.
