5 cards from this section. Quick, good the night before a test.
What is a zygote?
Think about the very first stage of development.
What happens during cleavage?
It’s about division but not growth.
What is the process by which a zygote is formed?
See the very first step in sexual reproduction.
True or False: Cleavage leads to the formation of the morula.
This is a direct consequence of the cleavage stage.
If a scientist identifies a defect in the cleavage stage of zygote development, hypothesize what effects it might have on the later stages of embryonic development.
Consider how each stage is dependent on the previous one!
Using examples from both plants and animals, compare the processes of fertilization and the early development of zygotes.
Think of contrasting environments and methods each uses!
