What is the job of the pistil in flowers?
The pistil is situated at a flower's center. It is a flower's female reproductive part that consists of the ovary at its base, style, and stigma. The role of the stigma, which is located at the top of the pistil, is to collect pollen. A pollen tube, which grows down through the style, connects the stigma to the ovary. The ovary contains ovules that are fertilized by the pollen.
What is self pollination of plant?
Self-pollination is a form of pollination that can occur when a flower has both stamen and a carpel in which the cultivar or species is self fertile and the stamens and the sticky stigma of the carpel contact each other to accomplish pollination. The term is inaccurately used in many cases where an outside pollinator is actually required; such plants are merely self fertile, or self pollenizing.
What is the process in which pollen from one plant is used to fertilize another?
cross fertilization
What does a pollen cell do as its job?
it is to eat a sandwich
What do plants use pollen for?
pollen is used to keep plants from dying its like food besides water sun photosynthesis and other things
What is the function of the stigma in the plant?
The stigma of the flower is used to collect pollen. When pollen is carried by wind or animals it gets stuck onto the stigma by a glue that the stigma produces.
How does the pollen reach the ovule in African violets?
Usually this is done by hand, the sac is very hard and needs to be carefully cut open by using a sharp exacto knife in order to display the powdery pollen. A small brush, q-tip or similar is used to transfer the pollen to the stigma.
What is the function of the pollen tube?
The pollen tube of most seed plants acts as a conduit to transport sperm cells from the pollen grain, either from the stigma (in flowering plants or angiosperms) to the ovules at the base of the pistil, or directly through ovule tissue in some gymnosperms (conifers and gnetophytes).

Ways pollen can move?
There are three common kinds of pollination: self pollination, wind pollination, and insect pollination. •Self pollination is when the pollen in the stamen (male part of the plant) drops into an ovule (egg) in the ovary of the stigma (female part) of the same plant. This is why it is called self pollination. • Wind pollination occurs in plants that are all-male (its flowers only containing stamen) and all-female (its flowers only containing the stigma). The stamen develops millions of pollen grains in the spring, as the chance of the pollen reaching an all-female plant is very little, and releases it in the summer. The few pollen grains that reach an all-female plant will be likely to reach an ovule in the stigma and pollinate the ovule. • Insect pollination is used by a lot of plants. This method of reproduction is when an insect such as a bee, butterfly, moth, or sometimes a bat, reaches a flower and sucks out the nectar in the flower. As they do this, the pollen gets stuck in their legs, and when they suck the nectar from the flower of another plant, the pollen gets onto the flower and into the stigma. If the pollen from a different type of plant is put into a stigma of a plant, pollination won't occur, so God has designed the bees of each hive to suck nectar from one kind of flower each day, so that the chance of pollination will be more.
What is the process in which pollen from one plant is used to pollinate the eggs in the flower of a different plant?
I think that there are two processes: Pollination and Fertilization Pollination is when the pollen grains meet on the stigma (female reproductive organ) of another flower. Fertilization is when the pollen actually meets the egg in the ovary. (Sperm joins with egg)

How is the word stigma used in a sentence?
Stigma is part of a plant
What is the process in which pollen from one plant is used to fertilize another?
cross fertilization
Is cutting asexual reproduction?
yes. cutting is asexual reproduction. because only one parent is used to grow a plant instead of the usual pollination of plant which includes the stigma and pollen grins of two plantss
What part of the plant is the corn silk in corn?
The female flower styles & stigma. The silk is the stringy fibers on the inside of the corn husk that stick out of the top to catch pollen. Corn silk is also used as a diuretic in herbal medicine.
