What is collected in the stamen?
pollen is collected in the stamen. It is made of pollen grains (male sex cells). these are carried by insects to a stigma ready to be fertilised. pollen is collected in the stamen. It is made of pollen grains (male sex cells). these are carried by insects to a stigma ready to be fertilised.
Why do pollen grains have air-sacs?
Pollen grains have air-sacs to help them float in the air and be carried by wind or insects for pollination. The air-sacs provide buoyancy and allow the pollen grains to be dispersed more effectively to reach other flowers for fertilization.
What is the male sex cells of a flower that can be carried by the wind?
The male sex cells of a flower that can be carried by the wind are pollen grains. These pollen grains are produced in the anthers of the flower and are dispersed by the wind to reach the female reproductive organs of other flowers for pollination.
Grains that surround and protect a plants sperm?
Pollen grains
How does the pollen grains tube reach the ovary?
Pollen tubes are extensions of pollen grains that grow and elongate to penetrate the ovary. They are guided by chemical signals released by the ovary, which direct the path of the pollen tube towards the ovule where fertilization can occur.

In cross pollination the pollen grains are carried from flower to flower by what?
usually insects
When pollen grains are carried to the female part of the plant what will happen to that part?
Pollination and hereafter, fertilization
What is the male sex cells of a flower that can be carried by the wind?
The male sex cells of a flower that can be carried by the wind are pollen grains. These pollen grains are produced in the anthers of the flower and are dispersed by the wind to reach the female reproductive organs of other flowers for pollination.
What is the function of pollen grains?
Matured pollen grains contained sperm cells. When Pollen grains are sticky, you have pollen. Pollen grains are contained in the pollen sac, with the purpose of helping plants reproduce.
Sperm contained in pollen grains are primarily transferred to an egg by?
Pollen is carried on the stamen of the male flower and has to be deposited on the stigma of a female flower to fertilise it.
Why are pollen grains different sizes?
Pollen grains come in different sizes depending on the plant species. Larger grains tend to be heavier and have a harder time being carried by wind, so they are usually found in plants that rely on insects for pollination. Smaller pollen grains are adapted for wind dispersal, allowing them to travel further distances.

How does the pollen reach the stigma?
some pollen grains reach to stigma by wind and some are carried by animals like rabbits and insects like butterfly, bee etc.
How does wind pollinate?
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.
