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.
When the pollen has traveled down the pollen tube and enters the ovary, it is called fertilization. This is the process where the male gamete in the pollen combines with the female gamete in the ovule to form a zygote, which will develop into a seed.
The tube that grows out of a pollen grain contains two sperm cells. These sperm cells are needed for fertilization in plants, where one sperm cell fuses with the egg cell to form a zygote, while the other fuses with the central cell to form the endosperm.
A pollen tube grows from a cell in the pollen and penetrates the style of the flower, allowing the sperm cells to travel to the ovule. This process is essential for fertilization to occur in plants.
An egg in a plant does not pass through a pollen tube. In plant reproduction, the egg cell is located in the ovule within the ovary of the flower. The pollen tube allows the sperm cells to travel from the pollen to the egg for fertilization to occur.
If a pollen grain lands near an ovule, it can lead to pollination, where the pollen grain forms a pollen tube that grows towards the ovule. Once the pollen tube reaches the ovule, fertilization can occur, resulting in the formation of a seed.
The sperm of seed plants form inside the pollen tube, a structure that develops from the pollen grain. The pollen tube grows towards the ovule to deliver the sperm cells for fertilization.
When the pollen has traveled down the pollen tube and enters the ovary, it is called fertilization. This is the process where the male gamete in the pollen combines with the female gamete in the ovule to form a zygote, which will develop into a seed.
A pollen tube grows from the pollen grain down through the style. The pollen tube enters the ovary and reaches an olvule. The sperm then travels down the pollen tube and fertilizes the egg in the ovule. So a pollen tube.

The long tube
how pollen tube grows down through the style
Pollen
Pollen grows a tube that travels down to the flowers ovary. From there, the nucleus of the pollen grains passes through the pollen tube to join the nucleus of the ovule to fertilize.
The pollen is made and stored by the anthers.In flowering plants the vegetative tube cell produces the pollen tube.
An egg in a plant does not pass through a pollen tube. In plant reproduction, the egg cell is located in the ovule within the ovary of the flower. The pollen tube allows the sperm cells to travel from the pollen to the egg for fertilization to occur.
