- some vector carry pollen from the anther of male to the stigma of female
- the pollen grain contains 2 nuclei - the tube nucleus and the generative nucleus. The generative nucleus later becomes 2 sperm nuclei
- the tube nucleus digests a tube down through the style to a small opening called the micropyle
-the two sperm nuclei then enter the ovary:
~ one fertilizes the egg -- seed (2n)
~ the other sperm nucleus fertilized 2 polar bodies to create the endosperm -- (3n)
- the endosperm encloses the seed, providing both nourishment and protection
* This process is referred to as double fertilization because 2 sperm are required to fertilize both the egg and the endosperm.
pollen
Indirect pollination refers to the process where a vector, such as wind or water, carries pollen grains from one plant to another for pollination to occur. Unlike direct pollination where pollinators like bees and butterflies transfer pollen directly between flowers, indirect pollination relies on external forces to facilitate the pollination process.
The movement of pollen from the stamen to the carpel is called pollination. This process is essential for the fertilization of plants and the production of seeds. Pollination can occur through various methods, including wind, insects, birds, and other animals.

Pollination
The process of pollination from same flower is called self-pollination. the process of pollination from another flower of same breed is called cross-pollination.
Fertilisation
This process is called pollination, which involves the movement of pollen grains from the anther (the male structure) to the stigma (the female structure) of a flower. Once pollination occurs, fertilization can take place, leading to the development of seeds and fruit.
pollen
Transfer of viable pollengrains fron anthers to the stigma is pollination.
Indirect pollination refers to the process where a vector, such as wind or water, carries pollen grains from one plant to another for pollination to occur. Unlike direct pollination where pollinators like bees and butterflies transfer pollen directly between flowers, indirect pollination relies on external forces to facilitate the pollination process.
pollination
Pollination is the process of how pollen is transferred by insects, wind, or rain to the pistol of a flower. This is essential to the fertilization of a plant.
because its natural and other tools might hurt the process
This transferring process is called pollination.
The transfer of pollen from the anther to the stigma is called pollination. This process is essential for fertilization and the production of seeds in plants. Pollination can occur through various means, such as wind, insects, birds, or other animals.
Cross pollination is where the pollen in one plant is used to pollinate those eggs that are available in a different plant. It fosters the vegetation process in Flora.
