What does an insect brush against before it picks up some of the flowers pollen?
Insects brush the stamen to get the pollen.
How is the process of pollination different from fertilization?
Pollination is the transfer of pollen to the ovule. Although it is a prerequisite to fertilization, several events must happen before fertilization occurs. Pollination is when pollen reaches the plant by wind or insect, whereas fertilization occurs when that pollen reaches the ovule and starts the beginnings of a new organism.
Does pollination happen right after fertilization?
Before.
What process must angiosperms go through before they can reprduce?
Before angiosperms can reproduce, they must undergo pollination, where pollen grains from the male anther of a flower are transferred to the female stigma. This is often facilitated by pollinators like bees or by wind. Following successful pollination, fertilization occurs when a sperm cell unites with an egg cell within the ovule, leading to seed development. Finally, the mature seeds are dispersed, allowing for the growth of new plants.
What part of the male marijuana plant do you cut off to make it a female?
To make a female marijuana plant, the male parts (pollen sacs) need to be removed before flowering to prevent pollination. This is typically done by identifying and removing the male plants from the growing area to avoid cross-pollination.
What will happen to the flower if the anther is removed?
If the anther is removed from a flower, it will not be able to produce pollen. The anther is the part of the flower's stamen that contains the pollen grains necessary for reproduction. Without pollen, the flower will not be able to fertilize its ovules and produce seeds, ultimately leading to a lack of fruit or seeds being formed.
When are the anthers of one plant removed so it cannot self-pollinate?
Anthers can be removed from a plant before they release pollen to prevent self-pollination. This can be done in controlled breeding programs to promote outcrossing or hybridization. Removing the anthers ensures that the plant can only be pollinated by pollen from another plant.

Do sperm develop before or after pollination?

How did Mendel control cross pollination?
Mendel controlled cross-pollination in his experiments by removing the pollen-producing stamens of one plant before they matured to prevent self-pollination. He then transferred the pollen from another plant to the female reproductive organ of the first plant to achieve controlled hybridization.

Why does the female squash flowers drop off before mature?
The female flower on a squash plant produces the squash when mature but will need pollination by a male flower. This can be done by transfering pollen from the anther of the male flower to the stigma of the female flower. Either an insect or person can do this.

Compare the self pollination and cross pollination?
Self pollination-The transfer of pollen from a male reproductive structure (an anther or male cone) to a female reproductive structure (a stigma or female cone) of the same plant or of the same flower.Self-pollination tends to decrease the genetic diversity (increase the number of homozygous individuals) in a population, and is much less common than cross-fertilization. Many species of plants have evolved mechanisms to promote cross-pollination and avoid self-pollination, though certain plants, such as the pea, regularly self-pollinate.Cross pollination-The transfer of pollen from the male reproductive organ (an anther or a male cone) of one plant to the female reproductive organ (a stigma or a female cone) of another plant.Most plants reproduce by cross-pollination, which increases the genetic diversity of a population (increases the number of heterozygous individuals). Mechanisms that promote cross-pollination include having male flowers on one plant and female flowers on another, having pollen mature before the stigmas on the same plant are chemically receptive to being pollinated, and having anatomical arrangements (such as stigmas that are taller than anthers) that make self-pollination less likely. Insects and wind are the main agents of cross-pollination.

Where is the flower's pollination stored before pollination?
Before pollination, the pollen grains are stored in the anthers (male part) of the plant. During pollination, an insect (such as a bee) flies to the flower for nectar and some pollen from the anthers rubs off on it. When the bee travels to another flower, the pollen sticks to the stigma (female part). After pollination, fertilization can begin. Hope this helps.
