When a pollen grain is immature male gametophyte, it has two cells ,a generative cell and a tube cell. A pollen grain becomes a mature male gametophyte when the generative cell divides by mitosis to form two sperm cells. In most species, this process occures after the pollen grain lands on the stigma of a carpel and the pollen tube begins to form. $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
What else can I help you with?
Where are the seeds located in angiosperm plants?
Seeds in angiosperm plants are typically found within the ovary of the flower, which develops into a fruit once fertilization occurs. The seeds are contained within the ovary's ovules, which undergo fertilization and develop into mature seeds within the fruit.
Where in the plant does fertilization occur?
Fertilization in plants typically occurs in the ovary, where the female reproductive cells (eggs) are located. Pollen containing male reproductive cells (sperm) is transferred to the ovary, allowing fertilization to take place and initiate seed development.
Can fertilization take place without pollination?
No, fertilization in plants typically occurs after pollination. Pollination is the transfer of pollen from the male reproductive organ to the female reproductive organ of the same or a different plant, leading to the eventual fertilization of the ovule. Therefore, pollination is a necessary step for fertilization to occur in most plants.
In a plant the site of meiosis and fertilization is the?
In plants, meiosis occurs in the reproductive organs known as the anthers (in male parts) and ovules (in female parts). Fertilization, where the male gamete fuses with the female gamete to form a zygote, typically occurs in the ovules.
What occurs when pollen sperm unites with the eggs?
When pollen sperm unites with the eggs, fertilization occurs. This leads to the formation of a zygote, which will later develop into a new plant. This process is essential for sexual reproduction in plants.

Where the fertilisation occur in plant?
Fertilization in plants typically occurs in the ovule, which is located within the ovary of the flower. The pollen must land on the stigma of the flower, germinate, and grow a pollen tube down to the ovary to deliver male gametes for fertilization to take place.
Where and when does fertilization ocur?
Fertilization occurs whenever a male sperm cell meets a female egg cell. For mammals, it is in the uterus, but in plants, it is the stigma and ovary.
Fertilization normally occurs where?
Fertilization normally occurs in the fallopian tubes. The sperm swim to the fallopian tubes and wait for ovulation to occur, they then swim to meet the egg. Once fertilization occurs the fertilized egg travel down to the uterus where it implants, and this is when a female is pregnant. In higher plants (angiosperms) fertilization occurs in the embryo sac. Out of two male gametes released from the pollen tube one fuses with the egg while the other one fuses with secondary nucleus (secondary nucleus is formed by the fusion of two polar nuclei). Thus, double fertilization occurs in such plants. The embryo develops from the zygote and the endosperm develops from triple fusion.
Which group of plants produce double fertilization?
Double fertilization occurs in angiosperms, which are flowering plants. It involves the fertilization of both the egg cell and the central cell in the ovule to form the embryo and endosperm, respectively. This process is unique to angiosperms and plays a crucial role in seed development.

What is a tiny chamber containing the plants ovules?
The tiny chamber containing the plant's ovules is called the ovary. It is typically located at the base of the flower and is a part of the female reproductive system in plants where the ovules are produced and stored before fertilization.
How is fertilization in flowering plants different from fertilization in other plant groups?
Fertilization in flowering plants is achieved by transferring the male gamete through pollen tube whereas in nonflowering plants the male male gametes are motile and transferred in aqueous medium.
How is fertilization in seed plants differ fertilization in seedless plants?
