Question 14

what are germ layers and what are the two we are focusing on?

Answer 14

germ layers are groups of cells that interact with each other during embryonic development and lead to the formation of all organs and tissues
we are focusing on two and three germ layers

Question 15

what is the two germ layer?

Answer 15

real name- diploblastic: made of the ectoderm (outside tissues) and endoderm (inner linings of the body -digestion )

Question 16

what is the three germ layer?

Answer 16

real name- triploblastic: made of ectoderm(skin/nervous system) mesoderm (muscular/skeleton) and endoderm (internal organs)

Question 17

what is acoelomate in the body?

Answer 17

solid body wall, body cavities and walls (mainly related to triploblastic

Question 18

what is pseudocoelom in the body?

Answer 18

fake body cavity -typically fills with fluid -cavity could collapse, unlikely ?

Question 19

what is a coelomate in the body?

Answer 19

a true body cavity
