What else can I help you with?
When pollen lands on the stigma is this pollenination or fertilasatoin?
It is called as pollination. Here the pollen grains are transmitted from one flower to other flower. Pollen grains may be transmitted in the same flower from the stamen to stigma.
What can anthers produce?
The anther produces pollen grains which would be transferred to other plant's stigma which will receive the pollen grains when an insect fly pass it then the pollen grains will be stuck on its wings.
Where could you pick up the pollen in a flower?
Pollen can be found inside the anthers, which are part of the flower's stamen. Bees and other pollinators collect pollen when they land on a flower, rubbing against the anthers and picking up the pollen grains.
What is the defference between self and cross pollination?
Self pollinationWhen pollen grains from a flower are carried to the stigma of the same flower or on the other flower of the same plant, the phenomenon is called self pollination.Cross pollinationWhen the pollen grains from a flower are carried to the stigma of the flower on other plant, the phenomenon is called cross pollination.
Where are pollen grains transported from?
pollen grains are transported from the microsporangium (contained in the anther of an angiosperm flower, male cone of a coniferous plant, or male cone of other seed plants)
What is the male sex cells of a flower that can be carried by the wind?
The male sex cells of a flower that can be carried by the wind are pollen grains. These pollen grains are produced in the anthers of the flower and are dispersed by the wind to reach the female reproductive organs of other flowers for pollination.
In angiosperms how do the sperms get to the part of the flower containing the egg?
In angiosperms, the sperm are typically carried to the part of the flower containing the egg by pollen grains, which contain the male gametes. These pollen grains are transferred by wind, insects, birds, or other pollinators to the stigma of the flower where they can then travel down the style to reach the ovary and fertilize the egg.
How do men pollinate flowers?
When man touches any flower,the some particles of the pollen grains sticks to the man's hand,nd when that man touches any other flower,the pollen in his hand transfers to the other flower, and pollination takes place
Were is pollen made?
Gymnosperms are heterosporous, producing microspores that develop into pollen grains and megaspores that are retained in an ovule. After fertilization (joining of the micro- and megaspore), the resulting embryo, along with other cells comprising the ovule, develops into a seed. The seed is a sporophyte resting stage.
What role do insects play in pollination?
insects play a major role in pollination by transferring pollen grains from one flower to other flower.eg: honey bee
How does the location of nectaries help to pollinate the flower?
Pollinators are attracted to the nectar. When they are feeding on the nectar, they pick up pollen and/or deposit pollen. The location of the nectaries is such as to make the pollinators touch the pollen to pick it up or to deposit it.
Why do pollen grains only produce tube in flower of their own species?
because
