Introduction
In the flower, male reproductive organ (androecium) consists of stamens
Pre-Requisites:
Development of certain organs, i.e., reproductive organs is necessary before fertilization.
Activity:
See the mounted slides of male reproductive organ under the microscope
Real Life Question:
How does pollen develop from stamen?
