Stigma
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.
When a pollen grain reaches the stigma of another flower of a plant of the same species what happens next is called?
When a pollen grain reaches the stigma of another flower of the same species, the process that follows is called pollination. The pollen grain germinates on the stigma, forming a pollen tube that extends down the style toward the ovary. This tube transports sperm cells to the ovule, leading to fertilization and the formation of seeds.
What are the parts of the carpel?
stigma,style and ovary are the three parts of the carpel.
What grows out of the pollen grain and into the stigma then carries the pollen nucleus down to the egg?
The structure that grows out of the pollen grain and into the stigma is called the pollen tube. Once the pollen grain lands on a compatible stigma, it germinates and forms this tube, which extends down through the style to reach the ovule in the ovary. The pollen tube carries the male gamete (pollen nucleus) to the egg cell for fertilization. This process is essential for sexual reproduction in flowering plants.

How do the sperm cells get from the stigma to the ovules?
Sperm cells move from the stigma to the ovules through a structure called the pollen tube, which grows down the style of the flower towards the ovary. This process is facilitated by the germination of pollen on the stigma, followed by the growth of the pollen tube to deliver the sperm cells to the ovules for fertilization.
How do the sperms nuclei in a pollen grain reach the egg nucleus in an ovule?
When they land on the style they begin to bore their way through the stigma all the way to the ovule. Through the tube made by the tube nucleus of the pollen grain: each pollen grain has two nuclei, one called generative nucleus which combines with the nuclei of the ovule, and the other called tube nucleus tube nucleus which forms a tube that penetrates the stigma till it reaches ovule then it degenerates.

Pollen tube.
What forms when stigma and pollen develop?
When stigma and pollen develop, they enable the process of pollination to occur. The stigma is the part of the pistil that receives the pollen, while the pollen contains the male gametes needed for fertilization. Once the pollen lands on the stigma, it can germinate and grow a pollen tube to transport the male gametes to the ovule for fertilization.
What is the sticky part of the pistil called?
The sticky part of the pistil is called the stigma. It is the receptive surface where pollen grains land and germinate to begin the process of fertilization.
What do a pistil consist of?
A pistil consists of three main parts: the stigma, style, and ovary. The stigma is the sticky top part that receives pollen, the style is a slender tube that connects the stigma to the ovary, and the ovary contains the ovules where fertilization occurs and seeds are produced.
