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.
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?
A pistol of a plant is the female reproductive organ that contains the ovary, style, and stigma. It is responsible for receiving pollen during fertilization in flowering plants.
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 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.
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).

The ovary contains ovules that are fertilized by the pollen.
Ways pollen can move?
Pollen can be moved by wind, water, animals (such as bees or birds), and gravity. Wind is the most common way pollen travels, especially for plants that produce large quantities of lightweight pollen. Water can carry pollen for aquatic plants, while some plants rely on animals to transfer pollen between flowers during pollination.
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 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)

A pistol of a plant is the female reproductive organ that contains the ovary, style, and stigma. It is responsible for receiving pollen during fertilization in flowering plants.

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 the process in which pollen from one plant is used to fertilize another?
cross fertilization
How is the word stigma used in a sentence?
The stigma of mental illness can prevent people from seeking help.
