Strobilus or cone is the reproductive structure of gymnosperms. ... Female Cones – the megasporophylls form a cluster and are called as the female strobili or cones. They bear the ovules having the megasporangium. Thus produces the haploid megaspores and a megaspore mother cell.

Answer 2

Answer:

Strobilus or cone is the procreative structure of gymnosperms. Both male and female strobili can be present on the same or different trees. Gymnosperm plants are heterosporous. They produce different spores, which are the haploid microspores and megaspores. Female Cones – the megasporophylls form a cluster and are called as the female strobili or cones. They bear the ovules having the megasporangium. Thus produces the haploid megaspores and a megaspore mother cell. hen the pollen grains are released from the microsporangium, they get dispersed through wind and reach the female cones. The pollen grain develops a pollen tube, which grows towards the archegonium. The discharge of male gametes happens near the mouth of the archegonium. The fusion of the male and female gametes occurs. After fertilization, a zygote develops to form the embryo and the ovule forms the seed. The following figure shows the life cycle of a gymnosperm.
