Question 18

Fertilization

Answer 18

1- the pollen reaches out its egg cells through the pollen tube

Fertilization
2- First fertilization

Answer 19

The first sperm reaches through the microphyle through the synergids and final to the egg. They fertilize and give rise to the zygote, later the embryo

Dispersal

Answer 42

Is not part of the plant structural development, the young ppant will not be able to separate itself from the parent plant It is an essential part of the plants life cycle Though dispersal, plants learned to adapt to their agents and agents adapt to the plants, this mutulaistic relationship is called CO-EVOLUTION
