Question

distinguish between pollination and fertilization mention the site and product of fertilization in a flower. draw a neat, labelled diagram of a pistil showing pollen tube growth and entry into the ovule​

Answer 1

Answer:

The process or mechanism of transfer of pollen grains from the anther to the stigma is termed pollination.

The fusion of male and female gametes giving rise to zygote is termed fertilization.

The site of fertilization is ovule.

The product of fertilization is zygote.

The main difference between pollination and fertilization is that pollination is the deposition of pollen grains from the anther to a stigma of a flower whereas fertilization is the fusion of the haploid gametes, forming a diploid zygote.

definations:-

Definition Pollination is the process of transfer of male gametes (pollen grains) in plants from the male reproductive part (anther) to the female reproductive part (stigma).

Fertilization is the process of fusion of haploid male and female gametes to form a diploid zygote to initiate the development of a new individual.

differences:-

1. Nature of the process :-Pollination is a physical process.
2. Type of process :-Pollination is an external process taking place outside the body of the plants.
3. occurs in :-Pollination occurs only in plants with flowers or differentiated male and female reproductive parts.
4. Pollination is a prerequisite of fertilization in plants and thus occurs before fertilization.
5. external factor:-Pollination is dependent on external biotic and abiotic factors.
6. pollen tube :-No pollen tube is formed during pollination.

fertillization as same

1. in nature process:- Fertilization is a genetic and biochemical process.
2. Fertilization is an internal process occurring inside the parts of the plants.
3. Fertilization occurs in all types of plants and animals reproducing by sexual mode of reproduction.
4. Fertilization occurs after pollination.
5. Fertilization is independent of external factors.
6. Fertilization in plants occurs via the formation of the pollen tube

Answer 2

Answer:

Pollination is the process of transfer of pollen grains from anther of a stamen to the stigma of a carpel while fertilization is the fusion of ale gamete and female gamete in the ovary to form a zygote. The site of fertilization is ovule. The product of fertilization is zygote.
