How does fertilization in plants take place?
the pollen grains after landing on the stigma germinate to send out pollen tubes through which the male gametes reach near the egg cell of embryo sac in the ovule to fuse with. this fusion of male and female gametes (egg cell) is called fertilization.
What is it called when pollen is transferred from the anther to another flowers stigma?
after that, the next thing in the part, which would be the ovary which will keep it in the ovule. fyi i dont think im correct.
In which part of a plant would meiosis occur?
mitosis occurs in pollen sacs contained in the anther of the stamen and also in the ovule of the carpel. Edited answer: Mitosis takes place at all growing points (apical and intercalary) to increase the number of somatic cells.
What would happen if there would be no ovary on a plant?
They could not produce seeds which is for reproduction.
Is pollen a liquid?
i would say its a solid.
How could a heavy rainfall on a fruit orchard in the spring result in a poor fruit yield in the fall?
I think that heavy rain on a fruit orchard in the spring would cause a poor fruit yield because all the pollen would be washed away, and therefore, the eggs would not be fertilized. The ovary, in which the ovules are contained, become the fruit once all the ovules are fertilized. The pollen is produced in the anther, and then they are transported to the pistil by different insects. The pistil contains the stigma, which is a sticky receptive surface where the pollen fall. The stigma also contains the style, which is the pollen tube through which the pollen reach the eggs. Now, if there is heavy rainfall, the pollen may not stick to the stigma, and then be washed away, or the insects may not come and transport the pollen to the stigma, which means that the ovary would never become a fruit.
What does pollen mean?
Pollen is basically the male "seeds" of plants. Just like we have males and females, plants have male and female parts to reproduce. The plant equivalent to a female would be a flower (it often contains an ovary where the pollen goes).
What will happen to the plant if it does not have the phloem tube?
Then the pollen would not be able to reach the ovule therefore it will not be able to make a seed
What is the purpose of corn silk on a corn plant?
The anther of a corn plant is at the very top. The anthers, attached to their filament, make up the stamen. The stamen produce pollen. The silk on the ear of corn is the pistil, made up of a stigma, a style, and an ovary. Each thread of silk is attached to an ovary (potential seed), which will develop into a kernel of corn. The pistil must receive some pollen from the anthers in order to fertilize the ovary and make a kernel of corn. Without the silk (pistil), there would be no kernel. Removing all of the pistils from an ear of corn will result in no corn on the cob.
How would plants reproduce?
Flowering plants reproduce by transferring pollen from a male organ (anthers) to a female organ (stigma)), the pollen grains germinate and send out the pollen tubes in the ovules. There the nucleus of the male cell joins with that of a female cell, and ovary starts growing in the form of a fruit. The ovules get convertd in to seeds. On maturity these seeds are dispersed and germinate to form new plants.
What is the importance of pollination?
Pollinators, such as bees, butterflies, flies, birds, and bats transport pollen from flower to flower (of same species). The pollen (sperm) is transported to a flowers pistil, travels down a pollen tube, and reaches the ovary (egg cell). The pollen and egg join to fertilize and produce a seed. Without pollinators, flowers can not bare fruit. Many common foods would not exist such as tomatoes, cucumbers, and mustard seeds.
What does the pistel do on a flower?
Pistil or the female reproduction structure is the innermost whorl, located in the center of the flower. Often vase-shaped, the pistil consists of three parts: the stigma, the style and the ovary.

What comes first fertilization or ovulation?
Ovulation has to happen first before fertilization can take place. Otherwise, the egg would still be in the ovary and the sperm wouldn't be able to reach it.
Do roses attract bees?
Honey bees have difficulties with some culitvated species of rose where the petals are large and tight because their proboscis would not be long enough to reach the nectar, but bumble bees have a longer proboscis and would be able to reach. Honey bees do forage from the simpler rose flowers.
Where would you find pollen in a plant?
We will find pollen and pollen sacks on an androecium also known as stigma of a plant.
