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 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
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.
What part of the plant is the corn silk in corn?
The female flower styles & stigma. The silk is the stringy fibers on the inside of the corn husk that stick out of the top to catch pollen. Corn silk is also used as a diuretic in herbal medicine.

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).

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 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)
