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 pollen tube grow before or after pollination occurs?
Before
Does pollination happen right after fertilization?
Before.
Does pollination occur before fertilisation?
yes
What will happen to the flower if the anther is removed?
why anthers are removed from flowers before selective pollination
When are the anthers of one plant removed so it cannot self-pollinate?
Before dehiscence of anther lobes
What does an insect brush against before it picks up some of the flowers pollen?
Insects brush the stamen to get the pollen.
Do sperm develop before or after pollination?
Sperm develops before pollination. sources:life science book
How did Mendel control cross pollination?
He removed stamens before they matured! *side note* Shouldnt you be doing this yourself? Haha dont worry, I was too!!;)

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.
Does pollen tube grow before or after pollination occurs?
Before
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.
Does pollination happen right after fertilization?
Before.
Does pollination occur before fertilisation?
yes
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.
