How is the sticky nature of the stigma related to its function?
The sticky nature of the stigma helps to trap pollen grains, allowing for successful pollination to occur. This stickiness facilitates the adhesion of pollen grains, improving the likelihood of pollen germination and fertilization. Overall, the sticky stigma plays a crucial role in the reproductive process of plants by enhancing the efficiency of pollen transfer.
What produces pollen grains?
Pollen grains are produced by the male reproductive organs of flowering plants called anthers. Anthers contain pollen sacs where pollen grains develop and mature.
What contains two pollen sacs with pollen grains?
A pollen sac is found in the anther of a flower, which contains pollen grains. Each anther typically has two pollen sacs, known as microsporangia, where pollen grains are produced via meiosis.
What are grains that produce sperm cells called?
Microspore mother cell after undergoing meiosis produces pollen grains, and the pollen grains during germination produce sperms by undergoing pollen mitosis.
What are Stalks that form pollen?
Stalks are structures that support the pollen grains in flowers. They connect the pollen grains to the anther, where the pollen is produced, and help in the dispersal of pollen for plant reproduction.
Are pollen grains haploid or diploid if they have two nuclei the generative and the tube nuclei?
Pollen grains with generative and tube nuclei have two haploid nuclei.
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.
Grains that surround and protect a plants sperm?

What are pollen grain?
pollen grains are little grains in side a flower
Which part of the stamen contains pollen grains?
The anther is the part of the stamen that contains the pollen grains. These pollen grains are the male reproductive cells that are essential for the process of pollination.
What produces pollen grains?
Pollen grains are produced by the male reproductive organs of flowering plants called anthers. Anthers contain pollen sacs where pollen grains develop and mature.
What contains two pollen sacs with pollen grains?
A pollen sac is found in the anther of a flower, which contains pollen grains. Each anther typically has two pollen sacs, known as microsporangia, where pollen grains are produced via meiosis.
Where are pollen grains produced?
pollen grains are produced in pollen sac of anthers which are present on the male gamets of flower
What are grains that produce sperm cells called?
Microspore mother cell after undergoing meiosis produces pollen grains, and the pollen grains during germination produce sperms by undergoing pollen mitosis.
What are Stalks that form pollen?
Stalks are structures that support the pollen grains in flowers. They connect the pollen grains to the anther, where the pollen is produced, and help in the dispersal of pollen for plant reproduction.
What is the job for stigma?
It allows landing of pollen grains and germination of compatible pollen grains only.
