Self-Pollination
its actually cross pollination
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.
A tobacco plant typically has four pollen sacs (microsporangia) on each anther. Each of these sacs contains numerous pollen cells, which are the male reproductive cells that will be dispersed for fertilization. The exact number of pollen cells can vary, but it is typically in the thousands for each anther.
Cross-fertilization occurs when pollen from one plant is transferred to the stigma of another plant. This can happen through wind, insects, or other means. Once the pollen reaches the stigma, it can travel down the style to the ovule, where fertilization takes place and seeds are produced.
After fertilization, the pollen grain is no longer needed by the plant. The pollen's primary role is to deliver sperm cells to the ovule for fertilization, after which the fertilized ovule develops into a seed. Additionally, the stigma and style of the flower become less critical as the focus shifts to seed and fruit development.
The male productive structure of a plant is the stamen. It consists of an anther, which produces pollen, and a filament, which supports the anther. The pollen contains the plant's sperm cells and is necessary for pollination and fertilization.

The fertilizing powder produced by plants is called pollen. Pollen contains the male reproductive cells of a plant and is transferred to the female reproductive organs of the same or a different plant to enable fertilization.

Pollen from flowers on one plant can fertilize flowers on a different plant. What is this process called?'

The male productive structure of a plant is the stamen. It consists of an anther, which produces pollen, and a filament, which supports the anther. The pollen contains the plant's sperm cells and is necessary for pollination and fertilization.
The job of the anther is to produce and store pollen, which contains the male reproductive cells of a plant. The pollen is then transferred to the stigma, leading to fertilization in the process of plant reproduction.
Plants do not have sperm cells. In plants, fertilization occurs when a pollen grain (containing sperm cells) lands on the stigma of a flower and grows a pollen tube to deliver the sperm cells to the ovule.
The cells of the tetrad in a pollen plant are haploid, meaning they contain a single set of chromosomes. This haploid condition is important for sexual reproduction, as it ensures the resulting gametes have the correct number of chromosomes when they combine during fertilization.
