What is Ephedra: Reproductive Structures and Cycle about?
1. Ephedra is a heterosporous and dioecious plant that produces two types of spores, microspores and megaspores, on separate male and female plants. 2. The male strobili contain microsporangia that develop into pollen grains, while the female strobili contain ovules or megasporangia. 3. Fertilization occurs when pollen grains from the male plant germinate and the sperm fertilizes the egg cell inside the archegonium of the female plant, leading to seed and embryo development.
