Why did all the pollen grains come from the same healthy plant?
The pollen grains came from the same healthy plant because they were produced by the plant's male reproductive organs, called anthers. These anthers release pollen, which is necessary for fertilizing the plant's female reproductive organs and producing seeds for reproduction.
Is a pollen gains produced by the male part?
Yes, pollen grains are produced by the male reproductive organs of plants, known as the stamen. The pollen grains contain the male gametes that are involved in the process of fertilization when they come into contact with the female reproductive organs of a flower.
What is the difference between pollen and pollen grain?
Pollen refers to the microscopic reproductive structures produced by plants, while pollen grains are the individual units that carry the male gametes. Pollen grains are released from the anthers of flowers and are carried by wind or pollinators to fertilize the ovules of plants.
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.
Why do flowers have so many pollens grains and ovules?
For pollen grains, the answer is easy - not all pollen will reach another flower, it has to depend on wind or an animal vector, and some may be lost to rain or being brushed off by a non-pollinating organism that happens to come in contact with the pollen. So the more pollen produced, the better the chance that some will reach its intended target. For the number of ovules, this isn't well known. It's often thought to be related to the primitive or advanced development of the plant species. As a plant becomes more "advanced", the number of parts generally decreases, often through fusion of the parts.

What do pollen sacks look like?
Pollen sacs are structures found on the anthers of flowers in which pollen grains are produced and stored. They are typically small, oval-shaped structures that contain numerous pollen grains. Pollen sacs can vary in color, size, and texture depending on the plant species.
What are those white fluffy things floating in the air and where do they come from?
The white fluffy things floating in the air are called pollen grains. They come from plants, particularly flowers, trees, and grasses. Pollen grains are released into the air as part of the plant's reproductive process.
How many pollen grains are deposited into the female flower?
as many that stick to the stamen. it differs from plant to plant and it also depends on how many pollen grains stick to the insect that carries it. though once the pollen grain comes into contact with the stamen a pollen tube is created to reach the ovary. then two "sperm" come from this tube and one fertalizes the egg and one become the endosperm for nutrients for the egg/seed
Why are pollen grains different sizes?
Pollen grains come in different sizes depending on the plant species. Larger grains tend to be heavier and have a harder time being carried by wind, so they are usually found in plants that rely on insects for pollination. Smaller pollen grains are adapted for wind dispersal, allowing them to travel further distances.
What is pollinination?
Pollination means transfer of pollen grains from anther to stigma in plants.
Is a pollen gains produced by the male part?
Yes, pollen grains are produced by the male reproductive organs of plants, known as the stamen. The pollen grains contain the male gametes that are involved in the process of fertilization when they come into contact with the female reproductive organs of a flower.
In what structure do the pollen grains come in contact with the ovule?
Pollen grains come in contact with the ovule through the stigma, which is the receptive tip of the female reproductive organ (pistil) in a flower. Pollen grains germinate on the stigma, form a pollen tube, and then grow down to the ovule for fertilization.
What is the difference between pollen and pollen grain?
Pollen refers to the microscopic reproductive structures produced by plants, while pollen grains are the individual units that carry the male gametes. Pollen grains are released from the anthers of flowers and are carried by wind or pollinators to fertilize the ovules of plants.
What must happen to pollen grains in order for pollination to occur?
True pollen comes from artichokes in which farts come from natural gas.
Why do flowers have many pollen grains and ovules?

How do flowers help a plant?
Flowers aid a plant in reproducing. Bees come and get pollen from a flower, and in the prosess take pollen from the male part of a flower and it is then placed on the female part. The pollen then produces a pollen tube and will soon become fruit or seeds.
