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.
Where the pollen tube grow to or through?
The pollen tube grows out of or through the pollen grain.
Why sucrose cause the formation of pollen tubes?
Sucrose provides energy for the growth and elongation of pollen tubes through respiration. It also serves as a carbon source for cell wall synthesis and maintenance of turgor pressure, contributing to the physical growth of the pollen tube. Additionally, sucrose signaling pathways play a role in regulating gene expression and cellular processes involved in pollen tube growth.
Where do pollen tubes develop to transport the male sperm cells to the female egg cells in the ovary?
In the style
What is the function of the pollen tubes?
it sucks

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
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
Are all pollen tube of equal length?
No, not all pollen tubes are of equal length. The length of a pollen tube can vary depending on several factors, including the species of the plant, environmental conditions, and the compatibility of the pollen with the ovule. Additionally, the growth rate of the pollen tube can be influenced by the availability of nutrients and water in the surrounding tissue. Thus, while some pollen tubes may be similar in length, there is considerable variation among them.
Function of a style?
Style allows the growth of pollen tubes through it to the ovary
Where the pollen tube grow to or through?
The pollen tube grows out of or through the pollen grain.
What is the function of style of the plant?
To connect stigma with the ovary and facilitate the growth of pollen tubes
