What happens when pollen is moved from the anthers to the stigma?
Pollen grains contain the male gamete (sex cell).
Why is the number of petals and sepals in a rose not equal in numbers?
The petals of a flower are for photosynthesis (for energy) and for attracting other organisms (with bright colors) such as birds, insects, and mammals that transfer pollen from flower to flower, a.k.a., pollination, in order to reproduce (also see "cross-pollination). The sepals contain more chlorophyll which gives plants their green color, and are used for protecting the flower while in it's "bud stage". Cross-Pollination: When pollen is moved from the male structure of a flower and carried to the female structure of another flower by wind, insects, mammals, and birds, as well as fish on some occasions.
What is it called when pollen is moved from one flower to another?
well, the name of this movement is called pollination as you can see. If you think the movement of pollens is called nectar then u are wrong there because nectar is the liquid that comes from the plant so that is why it is wrong.
How did gregor Mendel cross pollinate flowers?
Mendel took the pollen from one pea flower and put it onto anothers pistil. In order for there to be no other pollination, he covered them with protective bags, he also moved some into a greenhouse.
Why is cross pollination has a bright colour?
A flower Is the means by which a plant reproduces. Some flowers contain both male and female organs. Some plants have separate female plants and male plants. The reason the flowers are often brightly colored or fragrant is that they need to attract insects, birds and bats to pollinate them. Pollen sticks on the pollinator's body and then is moved to the female organs of the plant. Different flowers have different colors to stand out from other plants. Some pollinators see different colors better than others. Plants that open at night have light colors to attract night insects and bats.
What must be moved from what part of the flower to another?
needles
What is a way that pollen can be moved from flower to flower?
Pollen can be transferred by the wind or by insects such as bees. Some flowers are also pollinated by animals such as bats and hummingbirds.

How do bees pollinate flowers?
Bees are attracted to flowers by their bright colours and their desire to collect nectar. Nectar tends to be found close to the base of the petals and as the bee attempts to reach it the bee brushes against the male stamens of the flower, which deposit pollen on to its fur. When the bee flies to another flower the same process occurs and some of the pollen which was already present on its fur may brush against the female parts of this flower and then serve to fertilise it.

What has to happen for a flower to be pollenated?
In order for a flower to be pollentated, the pollen from the stamen of a male plant must be moved to the stigma of a female plant. This is often done by bees which visit the plants in search of nectar to make their food known as honey.
Is a the word bumble bee a pronoun?
No, the word bumble bee is a noun, a singular, common, compound, concrete noun; a word for an insect; a word for a thing.A pronoun is a word that takes the place of a noun in a sentence. The pronoun that takes the place of the noun bumble bee is it for the singular, they for a plural subject and them for a plural object of a sentence or clause. Examples:A bumble bee was busy on a branch of apple blossoms. It moved from flower to flower carrying the pollen with it.Some bumble bees were busy on a branch of apple blossoms. They moved from flower to flower carrying the pollen with them.

How is pollen transferred from the stamen to the pistol?
Flowering plants have several different parts that are important in pollination. Flowers have male parts called stamens that produce a sticky powder called pollen. Flowers have a female part called the pistil. The top of the pistil is called the stigma, and is often sticky. To be pollinated, pollen must be moved from a stamen to the stigma. When pollen from a plant's stamen is transferred to that same plant's stigma, it is called self-pollination. When pollen from a plant's stamen is transferred to a different plant's stigma, it is called cross-pollination. Cross-pollination produces stronger plants. The plants must be of the same species. For example, only pollen from a daisy can pollinate another daisy. Pollen from a rose or an apple tree would not work. Pollination occurs in several ways. People can transfer pollen from one flower to another, but most plants are pollinated without any help from people. Usually plants rely on animals or the wind to pollinate them. When animals such as bees, butterflies, moths, flies, and hummingbirds pollinate plants, it's accidental. They are not trying to pollinate the plant. Usually they are at the plant to get food, the sticky pollen or a sweet nectar made at the base of the petals. When feeding, the animals accidentally rub against the stamens and get pollen stuck all over themselves. When they move to another flower to feed, some of the pollen can rub off onto this new plant's stigma. Plants that are pollinated by animals often are brightly colored and have a strong smell to attract the animal pollinators. Another way plants are pollinated is by the wind. The wind picks up pollen from one plant and blows it onto another. Plants that are pollinated by wind often have long stamens and pistils. Since they do not need to attract animal pollinators, they can be dully colored, unscented, and with small or no petals since no insect needs to land on them.
How did mendel ''cross fertillize'' his plants?
Mendel took the pollen from one pea flower and put it onto anothers pistil. In order for there to be no other pollination, he covered them with protective bags, he also moved some into a greenhouse.
Why do plants need pollination to occur?
About 65 percent of flowering plants require insects for pollination to complete seed production. About 20 percent of all insects feed on the nectar of flowers as part of their life cycles. The plant and insect world are codependent for survival.
What do pollen and sperms both do on a plant?
Scientifically speaking the term sexual reproduction simply means that two components (gametes) are required for production of a new generation (offspring). Each of the two components carries in it one half of the chromosomes of any normal cell in the parent which produced it. The sperm is usually the gamete that moves away from its parent to join the gamete from the more stationary parent. Pollen is a special case. Each grain contains a nucleus that "directs" the growth of the pollen tube and germ cells (sperm) that ultimately join with the gamete from the ovule and form an embryo. So, in answer to your question, pollen contains the sperm cells. As the pollen fly away, they land on the bulb of the flower and tiny tubes form from the pollen to the ovules. The sperm then moved to the ovule through the tube and fertilizes the flower.
