Using the higher magnification objective lens will enable you to observe a larger number of pollen grains, but they will appear larger and more detailed due to the increased magnification. Conversely, using the lower magnification lens will allow you to see fewer pollen grains in the field of view, but they will appear smaller and less detailed.
The structure grown by a pollen grain that contains two sperm nuclei is called the pollen tube. The pollen tube is responsible for delivering the sperm nuclei to the ovule for fertilization in plants.
The anther is the male reproductive organ of a flower that produces and releases pollen grains, which contain the male gametes (sperm cells). It plays a crucial role in the process of pollination, where pollen is transferred from the anther to the stigma of a compatible flower for fertilization to occur. The anther is essential for sexual reproduction in flowering plants by facilitating the transfer of genetic material between plants.
Yes because pollen grains form on the tip of the anther.
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
Pollen grains with generative and tube nuclei have two haploid nuclei.
Pollen is scattered by the wind or by animals.
Pollen grains are formed within the anthers of flowering plants, which are the male reproductive structures where pollen grains develop and mature. The process of pollen grain formation is called microsporogenesis.
By sending their male gametes to the female gametes through their pollen tubes after germination of pollen grains.
they produce a tiny tube that the pollen grains travel to the egg cell.
I think as it lands on flowers the pollen sticks to tiny little hairs on its legs.

Two meiotic divisions are required in the sexual life cycle of a pea plant to produce 100 seeds. The first meiotic division occurs in the formation of pollen grains in the anthers of the flower, while the second meiotic division occurs in the development of ovules in the ovary. Each seed contains genetic material from both the male and female parent, contributing to genetic diversity.
