Question

can anyone please make me understand about the process of fertilisation(fertilization) in plants

Answer 1

The pollen grains in stamen are transferred to sttigma , by means of agents like wind , water , or animal . This process is called pollination . If the transfer of pollens occur in the same flower it is self pollination . And when transferred to anyother flower it is cross pollination .

Once the pollen grains reach the suitable stigma , a tube grows out of it that travels through the style & reaches the ovary , where it releases 2 male gametes .

One of the male gametes fuses with the egg present in the ovule & forms zygote , in a process is called as syngamy.

The other male gamete fuses with 2 polar nuclei present in the ovule . This process is called as triple fusion .

The ovary grows rapidly & ripens to form fruits . The embryo that is contained in the seeds develops into seedlings under appropriate conditions . This process is called geremination .

Since 2 fusions ( syngamy & triple fusion ) take place in the reproduction , the process is called double fertilization .


I HOPE IT WILL HELP U......
THANK U :)

Answer 2

plant fertilisation is the joining of male and female gamate resulting in zygote it can cosist of many process like pollination, germination & pentration of ovule......
