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
What are the reproductive structures of genosperms?
Most Gymnosperms are diecious with the male and female reproductive organs on different plants. The male "flower" produces pollen and the female "flower" contains the ovary. Many female gymnosperms produce cones that house the fertilized eggs until the seeds are mature.
How does pollen get to one place to another?
Pollen is moved from one place to another by pollinators like bees, butterflies, birds and wind. These pollinators carry pollen grains from one flower to another, facilitating the fertilization process in plants. This movement of pollen is crucial for the reproduction of many plant species.
The nucleus in each cell in the stem of a plant contains 32 chromosomes How many chromosomes are there in the nuclei of its pollen grains?
Pollen grains are produced via meiosis, which halves the chromosome number. Therefore, the pollen grains would contain 16 chromosomes.
How do you use the word anther in a sentence?
The anther is the part of a flower that produces pollen.Bees are crucial in the reproduction of many plants, as they move the pollen from the anther to another flower.
Why doesva flower have so many pollen grains than ovules?
flowers produce more pollen grains because the anther makes the pollen it then the stigma collects pollen and the petals of flowers atract insects or birds.
What are the inside parts of a flower?
It contains stigma, style, ovary, ovul, anther, filament, pollen grains, pollen tube , sepal, petals, and many more in a flower.

What do male cones produce?
Male cones produce many pollen grains to enhance its reproductive rate & hence its evolutionary success

A conifer that has both male and female cones will produce many more pollen grains than ovules How does that help the conifer reproduce?
The wind usually scatters the pollen grains of conifers. The likelihood of pollen reaching female cones is increased when there are large amounts of pollen.
What is pollen analysis?
Pollen grains are the microscopic male reproductive particles released from flowering plants. As these grains are vital for the survival of flowering species, evolution has ensured that individual species produce different types of pollen grains. Pollen grains are also made of a resistant organic material (sporopollenin) that means they are often remarkably well-preserved in sediments many thousands of years old.

How do bees carry pollen from one flower to another?
Bees carry pollen from one flower to another primarily on their legs and bodies. As they visit flowers to collect nectar, their bodies brush against the anthers, picking up pollen grains. When they move to another flower, some of this pollen is transferred to the stigma, facilitating pollination. This process is crucial for the reproduction of many flowering plants.
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.
Why are pollen grains produce in large nos?
PollenPollen is made as a plants way of reproducing, the pollen from one plant must mix with the flower of another in order to bear fruit or seeds. Since plants and trees are spread over vast areas, huge quantities of pollen must be released to be sure that it reaches another plant of its kind and as many of them as possible.
Do all flowers have pollen in them?
No, they are only half of the equation. Pollen comes from the male parts of the flower. It is necessary for the fertilization of the female flower parts then the seed is fertilized and will be a mature seed that can grow. ----------------------------------------------- NO, pollen is the male gamete which joins with an ovule to make a plant seed.
