Pollen is produced in the anthers of flowers through a process called microsporogenesis. It begins with the division of microspore mother cells, which then undergo meiosis to produce haploid microspores. These microspores further develop into pollen grains, which contain the male gametes necessary for plant reproduction.
What else can I help you with?
What does pollen from the stamen reach?
Pollen from the stamen reaches the stigma of a flower, which is part of the pistil. This transfer is crucial for the process of fertilization, as it allows the sperm cells contained within the pollen to travel down the style to the ovary, where they can fertilize the ovules. This process is essential for the production of seeds and the continuation of plant species.
When pollen lands on another plant what is it called?
When pollen lands on another plant, it is called pollination. This process is essential for the transfer of pollen from the male reproductive organs (anther) to the female reproductive organs (stigma) of plants, enabling fertilization and seed production.
What is a pollen grain landing near an ovule produces?
When a pollen grain lands near an ovule, it can lead to pollination. This process involves the transfer of pollen grains from the male reproductive part to the female reproductive part of a plant, which can result in fertilization and the production of seeds.
What is the comparison of dandelion to pollen?
Dandelions are flowering plants that produce pollen as part of their reproductive process. Pollen is a powdery substance containing the male reproductive cells of flowering plants like dandelions. Dandelion pollen can be spread by wind or insects to fertilize other dandelion flowers, leading to seed production.
What does the sharing of pollen between flowers allow?

What is the stigmas job on a flower?
The stigma, which is covered with a sticky substance, catches the pollen.
Do sunflowers produce pollen?
Yes, sunflowers do produce pollen. The pollen is found in the flower heads, specifically in the disk florets at the center of the sunflower. This pollen is an important source of food for pollinators, such as bees, which helps in the plant's reproduction process. Additionally, sunflower pollen can be collected and used by beekeepers to enhance honey production.

What is the work of male part of flower?
Pollen production. Pollen is what fertilizes female flowers.
What is pollen shedder?
Pollen shedder refers to a plant that releases pollen from its anthers into the surrounding environment for pollination to occur. This process is vital for the reproduction of seed plants, where pollen grains are transferred from the male reproductive structures to the female structures to facilitate fertilization and seed production.
What involves the transfer of pollen from the stamen stigma of the pistil where it grows in the tube of the ovary?
The process you're describing is known as pollination, which involves the transfer of pollen from the anther (part of the stamen) to the stigma (part of the pistil) of a flower. Once the pollen lands on the stigma, it germinates and grows a pollen tube down through the style into the ovary, where fertilization occurs. This process is essential for the production of seeds and fruit in flowering plants.
What is the process of pollen being transefrrered called?
The process of pollen being transferred from the male reproductive organ of a flower to the female reproductive organ is called pollination. This process is essential for fertilization and the production of seeds. Pollination can occur through various methods, including wind, water, insects, birds, and other animals.
What do sepals do in plant production?
They produce pollen
