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.
How does the pollen get to the ovule to fertilize it?
Pollen is transferred from the male reproductive organ (anther) to the female reproductive organ (stigma) of a flower through pollination. Once the pollen lands on the stigma, it forms a pollen tube that grows down through the style and delivers the sperm cells to the ovule for fertilization.
What is the stigma of a daffodil?
The stigma is the female receptical of the daffodil flower. Located in the exact center of the flower it sits atop a style which connects it to the ovule. Covered in a sticky substance, the pollen grains will stick to to it and rehydrate releasing the sperm which will work it's way down the style to the waiting egg in the ovule.
What are the steps in the reproduction of an angiosprem from pollination to the seed disperal?
First, pollen falls on a flower's stigma. In time, the sperm cell and egg cell join together in the flower's ovule. The zygote develops into the embryo part of the seed.
What is the function of the pollen grains in the flower?
It takes the sperm into the male reproductive organ and then new flowers grow.

Describe where pollination and fertilization occur?
Pollination occurs when pollen is transferred from the anther to the stigma of a flower. Fertilization occurs when the sperm cell from the pollen joins with the egg cell in the ovule, usually located in the ovary of the flower.
What is transferring pollen grains from another to the stigma of a flower?
when pollen grain are transferred from the stigma the ovule of the flower , whats takes place
How does the pollen get to the ovule to fertilize it?

What are the four parts of a flower?
For a female is: style, ovary, ovule and stigma. For a male flower: anther and filament.
In what structure do the pollen grains come in contact with the ovule?
Pollen grains come in contact with the ovule through the stigma, which is the receptive tip of the female reproductive organ (pistil) in a flower. Pollen grains germinate on the stigma, form a pollen tube, and then grow down to the ovule for fertilization.
What is the stigma of a daffodil?
The stigma is the female receptical of the daffodil flower. Located in the exact center of the flower it sits atop a style which connects it to the ovule. Covered in a sticky substance, the pollen grains will stick to to it and rehydrate releasing the sperm which will work it's way down the style to the waiting egg in the ovule.
Name the six parts of a flower?
They are Female:style, ovary, ovule and stigma. Male:anther and filament.
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.

What part of the flower develops into a seed?
The female part, the ovaries at the base of the stigma.
