Question
Fertilization and seed development
You have learned that the fusion of egg and sperm produces a zygote. But how does the sperm reach the egg, and how does the zygote develop into a seed, which eventually germinates and grows into a mature sporophyte? In this activity, you will demonstrate your understanding of double fertilization and seed development in angiosperms.
Drag the statements to their appropriate locations on the flowchart of pollination, fertilization, and seed development.
