Pollen cells are specialized reproductive cells produced by plants for pollination. They are small and lightweight, making them easily carried by wind or pollinators. Pollen cells contain male gametes that are necessary for fertilization when they reach a compatible female structure on another plant.

What is a pollen cell?
seeds
How many chromosomes in a pollen cell?
A pollen cell typically has half the number of chromosomes compared to a somatic cell. In many plant species, this means the pollen cell has 1 set of chromosomes (haploid), while somatic cells usually have 2 sets (diploid). So, the number of chromosomes in a pollen cell depends on the species, but it is usually half the diploid number.
What is the fusion of pollen and ovule called?
The fusion of pollen and ovule is called fertilization. This process involves the union of the sperm cell from the pollen with the egg cell in the ovule, resulting in the formation of a zygote, which eventually develops into a seed.
Where are a plants sperm cells located before fertilization occurs?
In plants, sperm cells are located within the pollen grains. Pollen grains contain two sperm cells that are released when the pollen lands on the stigma of the flower during pollination. The sperm cells then travel through the female reproductive structures of the plant to reach the egg cell for fertilization to occur.
What happens between pollination and fertilisation?
After pollination, the pollen grain germinates and forms a pollen tube that grows down the style of the pistil to reach the ovule. Fertilisation occurs when the sperm cell from the pollen grain fuses with the egg cell in the ovule, resulting in the formation of a zygote.
Special features in pollen?
There is 1 very special about a plant's pollen. A plant's pollen is the plant's sexual form of reproduction and it is done outside of the plant.
What special cell is found in pollen and ovules?
That would be called a Gamete.
Is the pollen cell plant cell?
Yes, the pollen cell is a plant cell.
What type of cell does pollen contain?
It has pollen cell
What are the special features of a sperm cell?
they have long tails for swimming and heads to get into the ovum
What colour is a pollen cell?
Pollen cells can be a variety of colors, including yellow, red, brown, and even green. The color of a pollen cell is influenced by the type of plant it comes from.
What is a pollen cell?
seeds
After the pollen grains land on the stigma what begins to grow from a cell in the pollen?
A pollen tube grows from a cell in the pollen and penetrates the style of the flower, allowing the sperm cells to travel to the ovule. This process is essential for fertilization to occur in plants.
How nucleus from a pollen grain fertilize a female egg cell?
How the nucleus from a pollen grain fertilize a female egg cell
How the nucleus from a pollen grain fertilizers a female egg cell?
How the nucleus from a pollen grain fertilize a female egg cell
What is the correct order of pollen traveling through a flower?
Once the flower is pollinated the pollen travels down the pistil until it reaches the female cell, the egg cell. When the pollen and egg cell join they form a seed.
What is the male sex cell from a pollen grain?
reproductive cell
