The pollen tube nucleus directs the growth of the pollen tube down through the pistil to the ovary
It takes the sperm into the male reproductive organ and then new flowers grow.
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 pollen tube of most seed plants acts as a conduit to transport sperm cells from the pollen grain, either from the stigma (in flowering plants or angiosperms) to the ovules at the base of the pistil, or directly through ovule tissue in some gymnosperms (conifers and gnetophytes).
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.
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.
how pollen tube grows down through the style
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.
