What is the difference between pollen and pollen grain?
Pollen refers to the microscopic reproductive structures produced by plants, while pollen grains are the individual units that carry the male gametes. Pollen grains are released from the anthers of flowers and are carried by wind or pollinators to fertilize the ovules of plants.
How do wind pollination occurs?
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.
What stores pollen in its knees?
The honeybee stores pollen in specialized structures on its hind legs called pollen baskets or corbiculae. These structures are concave areas surrounded by long hairs that help contain and carry the pollen back to the hive.
Do flowers carry pollen or does bees?
Bees typically carry pollen from one flower to another as they collect nectar. While flowers produce pollen, it is the bees that transfer it between flowers, aiding in the pollination process.
What is the combination of material from a pollen grain with an egg to form a seed?
When pollen grains land on the stigma of a flower, a pollen tube grows to deliver the male gametes to the ovule. The male gametes fuse with the female gametes in the ovule to form a zygote, which develops into a seed after fertilization. The seed contains genetic material from both the pollen grain (male) and the egg (female).
What is carried from flowers by bees?
Bees carry pollen from the stigma and the stamen, and also nectar.
How do animals help disperse seed?
Bees and wasps carry the male pollen to the female stigma's as they collect nectar from flower to flower. Also, in bigger animales e.g foxes, the pollen sticks to their fur as they pass the flower, and then when they rub against another flower, they transfer the pollen from their fur onto the stigma.
What is the primary function of the anthers on lily flowers?
The primary function of the anthers on lily flowers is to produce and release pollen. Pollen contains the male gametes needed for fertilization when it comes into contact with the stigma of the same or another flower.
How is pollen taken?
Insects visit the flowers to drink the liquid nectar the flower produces. In so doing, the insects brush against the pollen and carry some away on their bodies. When they visit the next flower, the pollen rubs off on to the stigma, when fertilization takes place.
What is the flower part called that holds the pollen?
They are called anthers. They carry the pollen.melesters
What part of a flower produces pollon?
The anther produces the pollen and then either gets blown by wind, floated on water, cross pollinates or self pollinates and then lands on the stigma of another flower of the same kind. The stigma then grows a tiny tube down the style and goes into the ovary and connects to the ovules.
What is the structure that allows sperm cells to move through the style of a flower?
The structure that allows sperm cells to move through the style of a flower is the pollen tube. Pollen tubes carry the sperm cells from the pollen grains on the stigma, through the style, and into the ovary where fertilization can occur. This process is crucial for sexual reproduction in plants.

How does pollen get to other flowers?
Pollen can be dispersed by wind, gravity, animals and water. However the largest group responsible for pollination are insects.Plants can also undergo self-pollination if the flower fails to be pollinated by an external factor.
Where does it carry its pollen?
They carry it in there litle legs :)
