The bird with the long beak because its adaptation allows it to reach the nectar at the bottom of the flower
yes, it is known as cross polliination. pollen grains of one plant transfer to stgma of another plant of the same species.
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.
Pollen grains are often called as microspores or male gametes. They are produced in pollen sacs present in pollen chambers in the anthers of the flower. They are produced due to repeated division of microspore mothercells and are haploid (n).
the transfer of pollen grains is called pollination. I the transfer of pollen is from the anther to the stigma of the same plant it is known as self pollination, whereas if the transfer of pollen is from the anther of one flower to the filament of a different flower, it is termed as cross pollination
Pollen grains are produced in vascular plants
Pollination means transfer of pollen grains from anther to stigma in plants.
it is the transfer of pollen grains from the anthers to the stigma of the same flower
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.
Pollen grains are carried by the wind, insects, birds, and other animals to fertilize plants for the purpose of reproduction. This process is essential for the transfer of male gametes to female reproductive organs in many plant species.
Pollen grains are produced via meiosis, which halves the chromosome number. Therefore, the pollen grains would contain 16 chromosomes.
The stigma.
Other plant from the surroundings that has anther (produce the pollen grains) will fertilise the ovule. when the pollen grains landed on the stigma, the ovule is then fertilise.
