Where does pollination in the flower occur?
Pollination in a flower typically occurs when pollen is transferred from the male reproductive organ, the stamen, to the female reproductive organ, the stigma. This can happen through various means such as wind, insects, birds, or other animals. Once the pollen reaches the stigma, it can lead to fertilization and the formation of seeds.
What is the sticky knob like ball on the top of the stamen?
The sticky knob-like ball on the top of the stamen is called the anther. It is responsible for producing and releasing pollen, which contains the male gametes of flowering plants. When pollination occurs, pollen grains from the anther can be transferred to the stigma of a flower, facilitating fertilization and the production of seeds.
What is it when pollen is transferred to a stigma from the same plant?
There are two types of pollination. When pollen grains are transferred from the anther to a stigma of the same flower or a flower on the same plant, it leads to self pollination. If the transfer involves different flowers on different plants, that is cross pollination.
Pollination of a flower takes place when?
Pollination occurs when the pollens from the anther of a flower is transferred to the stigma of the same or another flower. This is of two types- Self-Pollination(when the pollens from the anther of a flower are transferred to the stigma of the same flower or plant) and Cross-Pollination( when it gets transferred to the stigma of flower on another plant). Pollination is brought about by the help of various factors like insects, birds,wind, water.
Does pollen tube grow before or after pollination occurs?
Pollen tube growth occurs after pollination. Pollen grains are deposited on the stigma during pollination, which then germinate to produce pollen tubes. These tubes grow down through the style to reach the ovule for fertilization.
The transfer of pollen from a male structure to a female structure?
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.
What is the polynation?
Pollination is the process by which plants become fertilized. Pollination occurs when small grains of pollen are transferred from the male sexual organ of the plant, the anther, to the female sexual organ of the plant, the stigma. Pollination enables reproduction. Pollen blows through the air but much of the fertilization is due to bees and other insects, and some birds.

Pollination in a flower typically occurs when pollen is transferred from the male reproductive organ, the stamen, to the female reproductive organ, the stigma. This can happen through various means such as wind, insects, birds, or other animals. Once the pollen reaches the stigma, it can lead to fertilization and the formation of seeds.
Describe where pollination and fertilization occur?
Pollination occurs when pollen is transferred from the anther to the stigma of a flower. Fertilization occurs when the sperm cell from the pollen joins with the egg cell in the ovule, usually located in the ovary of the flower.
What is the part of the flower that receives the pollen grain from the anther?
The stigma recieves the pollen grain from the anther. It then travels down the pollen tube inside the style and goes to the ovary.

How does pollination take place in flowering plants?
Pollination is the process of transferring male pollen grains to the stigma of the plant (either the same plant = self-pollination, or another related plant close by = cross-pollination). The pollen grains germinate and grow down the style of the plant where the fuse with the female ovules, this results in an embryo being formed, which then becomes the seed of the plant. Pollination is aided by various (so called) "agents" or "vectors", these are things that assist in moving the pollen grains from the anther to the stigma. Vectors/ agents include: wind, insects (bees, butterflies, ants, moths etc.) water in some cases, animals (cats, dogs, sheep, cows, humans etc.)
What are the three ways in which pollination can occur?
Pollination can occur through wind, animals (such as bees, butterflies, and birds), and self-pollination (where pollen is transferred from the anther to the stigma of the same flower or a different flower on the same plant).
Does pollen tube grow before or after pollination occurs?
Pollen tube growth occurs after pollination. Pollen grains are deposited on the stigma during pollination, which then germinate to produce pollen tubes. These tubes grow down through the style to reach the ovule for fertilization.
How does pollination works?
On maturity of pollen grains , the anther lobes burst open and the pollen grains released in large amonut are carried by wind to several meters away to settle on feathery stigma as in case of plants of grass family.
