Front

What is the role of pollen in plant reproduction?

Back

Pollen carries the male gametes (sperm) to the female parts of flowers for fertilization.

Front

What do we call plants that reproduce using flowers?

Back

Plants that reproduce using flowers are called angiosperms.

Front

What is the difference between angiosperms and gymnosperms?

Back

Angiosperms have flowers and produce seeds enclosed in fruit, while gymnosperms have cones and produce seeds that are not enclosed.

Front

What is a life cycle?

Back

A life cycle is the series of stages that an organism goes through from birth to reproduction to death.
