What else can I help you with?
Function of a style?
Style allows the growth of pollen tubes through it to the ovary
What is the function of style of the plant?
To connect stigma with the ovary and facilitate the growth of pollen tubes
What the function of style?
Style facilitates the growth of compatible pollen tubes through it. It connects the stigma with the ovary of the pistil.
What is the function of the style in the flower?
The style in a flower is part of the female reproductive structure that connects the ovary to the stigma, allowing pollen to reach the ovules for fertilization. It plays a crucial role in the pollination process by providing a pathway for pollen tubes to grow and facilitate fertilization.
Do all pollen tubes reach the ovule?
No, not all pollen tubes reach the ovule. After pollination, multiple pollen tubes may grow down the style, but typically only one successfully penetrates the ovule to deliver sperm cells for fertilization. The competition among pollen tubes ensures that the most viable one reaches the ovule, while others may abort or be blocked along the way.
Does pollen tube grow before or after pollination occurs?
Pollen tube growth occurs after pollination. Pollen grains are deposited on the stigma during pollination, which then germinate to produce pollen tubes. These tubes grow down through the style to reach the ovule for fertilization.
What are the steps of pollination to the point that the seed is formed?
-pollen sticks to the stigma at the end of the pistil -pollen tubes grow down the pistil to the egg cells -sperm cells from the pollen moves down the tubes -fertilization combines DNA
What is the function of the pollen sacs in a flower?
the function of the pollen sac is to produce pollen (pollen grains). The pollen sac is the microsporangium of a seed plant in which pollen is produced. Most plants except coniferous plants contain four (4) pollen sacs.
How do two plants fertilize?
By sending their male gametes to the female gametes through their pollen tubes after germination of pollen grains.
On a flower what moves down to the ovary?
The male gametes in the pollen tubes.
Which part of the flowers do pollen tubes start to develop?
On the stigma of the carpel
Why is there a need for pollen tubes?
Pollen tubes are necessary for the transportation of sperm cells to the ovule in plants for fertilization to occur. They provide a pathway through which the sperm cells can travel to reach the egg cell, enabling the process of sexual reproduction in plants.
