What else can I help you with?
What best describes the relative number and appearance of the pollen grains observed using these two objectives?
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.
A structure grown by a pollen grain that contains two sperm nuclei is called what?
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.
Functions of anther?
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.
Does the anther hold pollen?
Yes because pollen grains form on the tip of the anther.
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
Are pollen grains haploid or diploid if they have two nuclei the generative and the tube nuclei?
Pollen grains with generative and tube nuclei have two haploid nuclei.
What are the two ways in which pollen grains are scattered?
Pollen is scattered by the wind or by animals.
Where does pollen grains form?
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.
How do two plants fertilize?
By sending their male gametes to the female gametes through their pollen tubes after germination of pollen grains.
Name two ways that plants ensure that their pollen grains have a greater chance of reaching the female part of their flowers?
they produce a tiny tube that the pollen grains travel to the egg cell.
How does a bee collect pollen?
I think as it lands on flowers the pollen sticks to tiny little hairs on its legs.
Give two ways by which pollen grains are scattered?
animal dispersal and wind dispersal

How many meiotic divisions are required in sexual life cycle of pea plant for producing 100 seeds?
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.
A structure grown by a pollen grain that contains two sperm nuclei is called what?
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.
