pollen grain
so pollination involves the transfer of 11. ________ grains from a flower'stamen to its stigma.
the _____ is pollen
The transfer of pollen grains from the stamen to the pistil is called pollination.
Pollination
Buttercups produce sticky pollen as a way to adhere to the bodies of pollinators, such as bees and butterflies, making it easier for the pollen to be transported between flowers for successful pollination. The stickiness helps the pollen grains remain attached to the insect as it moves from flower to flower, increasing the likelihood of successful reproduction for the plant.
Pollen grains are transferred to the stigma of a flower, where they germinate and form a pollen tube. This tube grows down through the style, which is the elongated part of the pistil, toward the ovary. As the pollen tube moves through the style, it carries sperm cells that will eventually fertilize the ovules in the ovary. This process is crucial for the reproduction of flowering plants.
A butterfly can carry pollen from one plant to another as it feeds on nectar. When it lands on a flower, pollen grains stick to its legs and body, and when it moves to another flower, some of this pollen is transferred, facilitating cross-pollination. This process is crucial for plant reproduction and helps maintain biodiversity in ecosystems.
Pollen
Pollination
When an insect like bee's lands on a flower, pollen sticks to it's legs. So when an insect moves to another flower pollen gets on that flower and so on and so on as the insect moves from one plant to another.
Wind moves pollen for some plants like grass and corn. Animal pollinators move pollen for many flowering plants.
The transfer of pollen grains from the stamen to the pistil is called pollination.
The male gametes in the pollen tubes.
Pollination
Anther pollen refers to the pollen grains produced by the anther, which is the male reproductive organ of a flower. These pollen grains contain the male gametes needed for fertilization when they land on the stigma of a flower.
the wind, bees, hummingbirds etc carry it everywhere
Whenever the bee moves pollen gets caught on its body and it moves from each flower to another
-pollen sticks to the stigma at the end of the pistil -pollen tubes grow down the pistil to the egg cells -sperm cells from the pollen moves down the tubes -fertilization combines DNA
The way the legs of most insects ,such as bees, have little hairs that pick up pollen. Then when it moves to another plant it leaves some of that pollen on the plant.
