How does a pollen tube form?
A pollen tube forms when a pollen grain lands on the stigma of a flower and germinates. The pollen grain absorbs water and begins to grow a tube that will penetrate the style of the flower and reach the ovary. This is a crucial step in the process of fertilization in plants.
How does sperm get from stigma to ovule in a flower?
In flowers, sperm are usually contained within pollen grains. These pollen grains are transferred from the stigma (the receptive surface) to the ovule (located within the ovary) through the elongated tube-like structure called the pollen tube. The pollen tube grows down through the style (the tube connecting the stigma and ovary) and delivers the sperm to the ovule for fertilization to occur.
How does the nucleus in a pollen grain get from the stigma to the ovary of a flower?
they germinate and grow a small tube all the way to the ovary
What is a pollen tube?
A pollen tube is a structure that develops from a pollen grain after it lands on the stigma of a flower. It grows down through the style of the flower to reach the ovary where it delivers the male gametes for fertilization to occur. This process is essential for plant reproduction.
When pollen lands on the stigma of a flower it grows a tube to travel down to the ovary is it true?
Yes, that's true. When pollen grains land on the stigma of a compatible flower, they germinate and develop a pollen tube that grows down through the style toward the ovary. This tube facilitates the transfer of sperm cells to the ovule, allowing for fertilization to occur. This process is essential for the reproduction of flowering plants.
What parts of a flower are needed for reproduction?
Ok, first off: know that there are both 'complete' and 'incomplete' flowers. Incomplete flowers are comprised of only male or only female parts, whereas complete flowers have both. The female parts of the flower are the ovary, eggs, pollen tube, pistil, and stigma. The male parts of the flower are the stamen, anthers, and pollen. The eggs of the flower are kept in the ovary; pollen from other flowers' anthers and stamens is received by the stigma and filters down through the pollen tube. The pollen fertilizes the eggs; fertilization is complete.

What are the parts of flowers involved in fertilization?
The female parts of the flower are the ovary, eggs, pollen tube, pistil, and stigma. The male parts of the flower are the stamen, anthers, and pollen. The eggs of the flower are kept in the ovary; pollen from other flowers' anthers and stamens is received by the stigma and filters down through the pollen tube. The pollen fertilizes the eggs; fertilization is complete.
What color tube is used for Complete CBC?
