What did Embryophyte emerge from?

Water

What is gametangia

Reproductive tissue, whose job is to build Gametes

Where does charaopyte build eggs and sperm

In the same gametangia because they’re all released in to water

How is gametangia arranged in Embryophyte

They have different gametangia for different gametes

What is the female and male gametangia in the embryophyte called

Female archegonia

Male antheridia

How does antheridia work

Looks Like a cup that fills up with rain and trigger sperm to swim out

What is the evolutionary advantage of separate reproductive structures to produce egg and sperm?

Minimize self fertilization

What happens to the egg and sperm in Embryophyte?

They do not release egg, and the sperm is chemically attracted to the egg

What is common is charophyte

Self fertilization because there is one structure, producing egg and sperm

What evolved in Embryophyte

Evolution of apical meristems

What is apical meristems

Tissues in a plant where mitosis is increased it is the spot of primary growth

Where are the two sets of apical meristems found
