Emasculation is not required when flowers are
Pollen grain (microspore) formation in Cyperus (Cypraceae) is
In family cypraceae, only one nucleus (out of 4) remains functional after meiotic division of microspore mother cell (similar to megaspore formation).
Male gametes or sperms are developed from generative cell by
Generative cell is haploid and 2 male gametes are formed from it by mitotic division.
From megasporocyte to egg cell, what processes are required ?
The study of formation, growth and development of new individual from an egg is called
Double fertilisation leading to initiation of endosperm inangiosperms require
The second male gamete entering the ovary fuses with two haploid polar nuclei to form triploid primary endosperm nucleus which develops into endosperm. This fusion of two male gametes with two different structures(egg and secondary nucleus) in the same female gametophyte is called double fertilization.
In angiosperms pollen tubes liberate their male gametes intothe
