What are female plant sex cells called?
Female plant sex cells are called ovules. They are located within the ovary of the plant and contain genetic material that can combine with pollen to form seeds.
Male gametophytes of flowering plants?
Male gametophytes of flowering plants, also known as pollen grains, are produced in the anthers of the flower. These gametophytes contain the male sperm cells and are dispersed by wind, water, or pollinators to reach the female reproductive structure of the plant. Once a pollen grain lands on the stigma of a flower, it germinates and grows a tube to deliver the sperm cells to the ovules for fertilization.
The sperm cells of a flowering plant are contained where?
In plants they are called gametes not sperm cells. The male gametes are found in pollen grains and the female gametes in the ovules (eggs). In angiosperms they are found in the parts of the flowers. Pollen is found in the anthers (male part of the flower) which are in the centre (attached to the fillament-like stamens) of the flower, the anthers and stamens surround the stigma and style (female parts of the flower). In gymnosperms they are found in the male and female cones attached to the plant.
What is the job of a stigma?
The stigma on a flower is responsible for receiving pollen during fertilization. It is the receptive surface where pollen grains adhere and germinate to produce a pollen tube that delivers sperm to the ovules. This process is essential for sexual reproduction in plants.
What is the structure that allows sperm cells to move through the style of a flower?
The structure that allows sperm cells to move through the style of a flower is the pollen tube. Pollen tubes carry the sperm cells from the pollen grains on the stigma, through the style, and into the ovary where fertilization can occur. This process is crucial for sexual reproduction in plants.
Are pollen and ovules gametes?
No, pollen and ovules are not gametes. Pollen is a male reproductive structure that contains sperm cells, while ovules are female reproductive structures that contain egg cells. Gametes are the actual sperm and egg cells involved in sexual reproduction.
How many sperm cells enter the plant ovule?
Plants do not have sperm cells. In plants, fertilization occurs when a pollen grain (containing sperm cells) lands on the stigma of a flower and grows a pollen tube to deliver the sperm cells to the ovule.
What is difference between somatic cells and gametes cells?
Somatic cells are not involved in sexual reproduction. These are most of the cells in your body. Gametes are sex cells (sperm and ovules/eggs).
What are female plant sex cells called?
Female plant sex cells are called ovules. They are located within the ovary of the plant and contain genetic material that can combine with pollen to form seeds.

Does the stigma of a flowere contain sperm cells?
The answer is no. The anther contains pollen which contains sperm cells. Mainly through pollination, the pollen from the anther travels down the pistil, and meets the egg where it fertilizes the egg.

The stigma on a flower is responsible for receiving pollen during fertilization. It is the receptive surface where pollen grains adhere and germinate to produce a pollen tube that delivers sperm to the ovules. This process is essential for sexual reproduction in plants.
What is the importance of pllen grains and ovules in plant reproduction?
Pollen grains contain the male gametes (sperm) needed for fertilization, and ovules contain the female gametes (eggs). When a pollen grain lands on the stigma of a flower, it germinates and grows a pollen tube to deliver the sperm to the ovule for fertilization. This process leads to the formation of seeds, ensuring genetic diversity and the continuation of plant species.
Is stigma to hold the plant?
No, a stigma is the tube (style), that pollen grains go down and meet ovules. I would guess that the stem hold the plant.
What fertilizes ovules to create seeds?
Pollination, the transfer of pollen from the male anther to the female stigma of a flower, is the process that fertilizes ovules to create seeds. Once pollen reaches the stigma, it travels down the style to fertilize the ovules within the ovary. This fertilization process leads to the formation of seeds, which eventually develop into new plants.
What part of a flower becomes the seed?
Angiosperms are FLOWERING PLANTS. The flower is the reproductive organ of an angiosperm. The female reproductive organ of a flower is the PISTIL. Three parts make the PISTIL: The stigma, the style and the ovary. The stigma is the sticky tip of the pistil. The style connects the stigma to the ovary. The ovary contains one or more ovules. Pollination occurs soon after a grain of pollen lands on the sticky stigma. The pollen produces a tube that grows through the style and into the ovule (remember that one or more ovules are inside the OVARY). A sperm cell is released from the tube to fertilize the egg cell in the ovule. The result is a SEED that may eventually become a new plant. So the seed develops inside the OVULE.
