What are the differences between pollination and fertilisation?

Question

Answer

.Pollination and # fertilization

Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma.

#fertilization is the fusion of gametes to initiate the development of a new individual organism.

Pollination later enables fertilization and the production of seeds, most often by an animal or by wind.

#The cycle of fertilisation and development of new individuals is called sexual reproduction.

in angiosperms, after the pollen grain has landed on the stigma, it develops a pollen tube which grows down the style until it reaches an ovary. Sperm cells from the pollen grain then move along the pollen tube, enter an ovum cell through the micropyle and fertilise it, resulting in the production of a seed.

#During double fertilisation in angiosperms the haploid male gamete combines with two haploid polar nuclei to form a triploid primary endosperm nucleus by the process of vegetative fertilisation.

Pollinating agents such as wind, water, bees and birds are necessary for pollination.

#Male and female gametes are necessary for fertilization to take place

Answer

Answer

Pollen grains are transferred to the female reproductive part of flower of either the same or other plant this process is called pollination this is followed by fertilization

FERTILIZATION

in human beings fertilization is internal the male amateurs(spearm) forms are released inside the female genital tract during sexual intercourse. sperms are highly active and motile millions of sperms are released in the vagina and they move upward through the cervix and uterus into the oviduct where they may encounter the egg finally in the fallopian tubes one sperm fertilize the ovum after the fusion of sperm and ovum zygote formed. fertilization is marked by the absence of menstruation in females

Answer

Pollination is a act of transferring something from male into female.
fertilisation means power of male to transfer.

Answer

Answer

Pollination:
Pollination is the process by which pollen grains are transferred from the male reproductive organ (anther) to the female reproductive organ (stigma) of a flower. It is a crucial step in the reproduction of flowering plants, as it enables the transfer of male gametes (sperm cells) to the female gametes (egg cells) for fertilization to occur.

- Nature of Pollination: Pollination is an external process that occurs in the plant kingdom, where the transfer of pollen grains takes place either within the same flower (self-pollination) or between different flowers of the same species (cross-pollination).

- Methods of Pollination: There are two main methods of pollination:
- Wind Pollination: In this method, pollen grains are light and often produced in large quantities. They are carried by the wind to reach the female reproductive organ of another flower. Wind-pollinated plants usually have inconspicuous flowers with no bright colors or nectar.
- Animal Pollination: This method involves the assistance of animals, such as insects, birds, or mammals, in the transfer of pollen grains. These animals are attracted to flowers by their bright colors, sweet fragrance, or nectar. As they visit the flowers in search of food, pollen grains stick to their bodies and are transported to other flowers.

- Purpose of Pollination: The primary purpose of pollination is to facilitate fertilization, ensuring the production of seeds and the continuation of plant species. It also promotes genetic diversity by facilitating the exchange of genetic material between different plants.

Fertilization:
Fertilization is the process that occurs after pollination, where the fusion of male and female gametes takes place. It is a crucial step in sexual reproduction, leading to the formation of a zygote and ultimately the development of a new individual.

- Nature of Fertilization: Fertilization is an internal process that occurs within the reproductive structures of plants. It involves the fusion of the male gametes within the pollen grain with the female gametes present in the ovule.

- Process of Fertilization: After pollination, the pollen grain germinates on the stigma and forms a pollen tube. This tube grows through the style and reaches the ovule. The male gametes then travel through the pollen tube and fuse with the female gametes (egg cells) present in the ovule. This fusion results in the formation of a zygote, which further develops into an embryo and eventually a seed.

- Role of Fertilization: Fertilization plays a crucial role in plant reproduction as it combines the genetic material from the male and female parents, ensuring genetic diversity in the offspring. It also triggers the development of the ovule into a seed, which contains the embryo and provides nourishment for its growth.

In summary, pollination is the transfer of pollen grains from the male reproductive organ to the female reproductive organ, while fertilization is the fusion of male and female gametes leading to the formation of a zygote. Pollination serves as the means of transferring pollen, while fertilization is the process that results in the formation of seeds and the development of new plants.
