Role of megasporophyll in the life of Cycas

1. Ovulation: The megasporophylls of Cycas are united to form a crown. The upper part of megasporophyll is called pinnule. At its base are 2-4 pairs of large and red ovules. The megasporophyll with the ovule looks like a snake’s hood. It is called Sarpamani. Inside the ovum are the female cells. Spore mother cells divide by meiosis to produce megaspore. Archegonia are formed from the female sperm. Ovules develop inside the archegonium.
2. Fertilization: Anthers are formed from the cymes of Cycas. Fertilization of sperm and egg occurs inside the anther. Fertilization results in the formation of a zygote.
3. Seed Formation: Embryo is formed from zygote. The embryo divides and becomes a seed. Cycas seeds are juicy, orange or red in color.
4. New Plant Formation: Cycas seeds germinate and produce new plants.
