Solution
| Pollination | Fertilization |
| It is the process of transfer of pollen grains from the anther to the stigma of the pistil of the flower. | It is the process of fusion of male and female gametes resulting in the formation of zygote. |
| This process leads to fertilization. | This process leads to formation of seeds. |
| Pollen tube formation does not take place in pollination. | After pollination, pollen tube forms for fertilization to occur. |
| Pollination occurs in flowering plants. | Fertilization occurs in every living beings which undergo sexual reproduction. |
The site of fertilisation in the flower is the ovule present in the ovary.
The product of fertilisation of male and female gamete is the zygote.
