Fertilization of egg cells by pollen from the same plant?
self-pollination
Does a egg if a plant pass through the pollen tube or something different?
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.
What is the fertilizing powder produced by plants called?
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.
Fertilization of an egg cells by pollen from different plant?
When pollen is transferred from one plant to fertilize the egg cell of a different plant, it results in cross-fertilization. This process increases genetic diversity and leads to the formation of seeds with different traits. Cross-fertilization can occur through various mechanisms such as wind, insects, birds, or other animals.
How many pollen cells are on one anther of tobacco plant?
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.
How does cross fertilization work?
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.
What is the yellow substance that holds the male cells of the plant?
The yellow substance that holds the male cells of a plant is known as pollen. Pollen grains contain the male gametes (sperm cells) necessary for fertilization in plants. They are typically produced in the anthers of flowers and can vary in color and texture depending on the plant species. Pollen plays a crucial role in the reproduction process, as it is often transferred to female structures for fertilization to occur.
Pollen from flowers on one plant can fertilize flowers on a different plant. what is this process called?
Pollen from flowers on one plant can fertilize flowers on a different plant. What is this process called?'
What is no longer needed for a plant after fertilization?
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.
Male productive structure of a plant?
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?
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.
How many sperm cells enter the plant ovule?
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.
