Sexual reproduction is a kind of reproduction, in which two parents (one male other female) are involved in the formation of new individuals. These parents produce gametes (specialized haploid cells) which on fertilization give rise to new individual. The individual is called hybrid. For sexual reproduction, angiosperms possess reproductive organs. These organs are the flowers. To understand reproduction in plants, [...]
It is a process in which a part of the plant body gets detached and develops in to a new independent plant. In lower plants it occurs through binary fission, budding, fragmentation, gemmae, resting buds, soredia (in lichens) etc. In higher plants, any part of the body maybe capable of vegetative propagation. Many plants produce modified stems, roots, and leaves, [...]
Agamospermy: This is the phenomenon of formation of embryos through asexual reproductive process without the formation of gametes (by gametogenesis) and the act of fertilization. Agamospermy is of the following three types: (i) Recurrent Agamospermy (Recurrent Apomixis; Apospory & Diplospory): In this type of agamospermy, a diploid embryosac is formed either from the diploid nucellar cells (a phenomenon called apospory, [...]
