Question

why cannot fertilisation take place in flowers if pollination does not occur?​

Answer 1

Answer:

here

Explanation:

Pollination is the process of transfer of pollen grains from the anther to the stigma of a flower(which means it is the male gamete) . Fertilization is fusion of gametes , if pollination does not there will be no male gamete for fusion, therefore without pollination fertilization cannot take place

Answer 2

Answer:

Pollination is the process by which pollen grains are transferred to the sigma. Once pollen grains land on stigma, they germinate to produce pollen tubes and subsequently to facilitate fertilization. Hence, fertilization cannot take place in flowers if pollination does not occur.
