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 you transport weathered material to one place to another?
It is called erosion when weathered material is moved from one place to another by natural forces like water, wind, or ice.
The hypothesis that continents have moved is called continental?
The hypothesis that continents have moved is called continental drift. This theory suggests that Earth's continents were once joined in a single supercontinent called Pangaea and have since moved apart to their current positions.
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.
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 does pollen get to one place to another?
Pollen is moved from one place to another by pollinators like bees, butterflies, birds and wind. These pollinators carry pollen grains from one flower to another, facilitating the fertilization process in plants. This movement of pollen is crucial for the reproduction of many plant species.
What happens when pollen is moved from the anthers to the stigma?
Pollen grains contain the male gamete (sex cell).
What must be moved from what part of the flower to another?
needles
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.

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.
Is pollen transferred from the pistol to the stamens?
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.

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.
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.
