What technique is used by stigma to catch pollen?
The technique used by stigma to catch pollen is called adhesion. The sticky surface of the stigma allows pollen grains to adhere to it when they come into contact, enabling successful pollination to occur.
How do plant breeders make sure that that only the pollen grains that they select get onto the stigma?
Plant breeders often use techniques such as bagging or covering the flowers to prevent unwanted pollen from reaching the stigma. They can also manually pollinate by carefully transferring selected pollen grains directly to the stigma of the desired flower. Additionally, they may remove the anthers from the flowers that they do not want to contribute pollen, ensuring that only the selected pollen is used for fertilization. This controlled approach allows for precise breeding and the development of specific plant traits.
What is the job of the pistil in flowers?
The pistil is situated at a flower's center. It is a flower's female reproductive part that consists of the ovary at its base, style, and stigma. The role of the stigma, which is located at the top of the pistil, is to collect pollen. A pollen tube, which grows down through the style, connects the stigma to the ovary. The ovary contains ovules that are fertilized by the pollen.
What is a self cross?
A self cross is a breeding method in genetics where an organism is crossed with itself or genetically similar individuals to maintain or amplify desired traits. This technique is often used in plant breeding to create uniformity in a population or to stabilize certain genetic characteristics.
What are air sacks used for in pollen?
Air sacs in pollen are used for buoyancy, enabling the pollen to float through the air and be carried by wind or pollinators to reach other flowers for fertilization. This helps increase the chance of successful pollination and reproduction for the plant.

The technique used by stigma to catch pollen is called adhesion. The sticky surface of the stigma allows pollen grains to adhere to it when they come into contact, enabling successful pollination to occur.
What is the function of the stigma in the plant?
The stigma of the flower is used to collect pollen. When pollen is carried by wind or animals it gets stuck onto the stigma by a glue that the stigma produces.
How does the pollen reach the ovule in African violets?
Usually this is done by hand, the sac is very hard and needs to be carefully cut open by using a sharp exacto knife in order to display the powdery pollen. A small brush, q-tip or similar is used to transfer the pollen to the stigma.

What is the function of the pollen tube?
The pollen tube of most seed plants acts as a conduit to transport sperm cells from the pollen grain, either from the stigma (in flowering plants or angiosperms) to the ovules at the base of the pistil, or directly through ovule tissue in some gymnosperms (conifers and gnetophytes).

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.

A self cross is a breeding method in genetics where an organism is crossed with itself or genetically similar individuals to maintain or amplify desired traits. This technique is often used in plant breeding to create uniformity in a population or to stabilize certain genetic characteristics.
What is the process in which pollen from one plant is used to pollinate the eggs in the flower of a different plant?
I think that there are two processes: Pollination and Fertilization Pollination is when the pollen grains meet on the stigma (female reproductive organ) of another flower. Fertilization is when the pollen actually meets the egg in the ovary. (Sperm joins with egg)
What are air sacks used for in pollen?
Air sacs in pollen are used for buoyancy, enabling the pollen to float through the air and be carried by wind or pollinators to reach other flowers for fertilization. This helps increase the chance of successful pollination and reproduction for the plant.
What is a pistol of a plant?
It is the female part. The stamen are the male parts.
What is the process in which pollen from one plant is used to fertilize another?
cross fertilization
