Best answer: What happens when male gamete reaches the ovule?

A pollen tube grows through the tissues of the flower until it reaches an ovule inside the ovary . The nucleus of the pollen grain (the male gamete ) then passes along the pollen tube and joins with the nucleus of the ovule (the female gamete). This process is called fertilisation .

What will happen to the ovule once it is fertilized by the male gametophyte?

Once fertilization has occurred, the embryo develops within the female gametophyte, and the ovule becomes the seed, complete with a food source (the gametophyte tissue) and a seed coat (the integument).

How the male gamete reaches the female gametes present in the ovule?

The male gamete in the pollen grain reaches the female gamete present in the ovule by the process of pollination. The pollination is done by different external agents such as insects, air, water, birds, animals, human beings etc.

What release male gametes into ovule?

After a pollen grain lands on the stigma, male gametes are delivered to the ovule via the pollen tube, which grows rapidly through the sporophytic tissues of the style and into the embryo sac (female gametophyte) within the ovule.

How does the male gamete reach the female gamete?

Male gamete from the pollen grain reaches the female gamete by passing through. Pollen tube develops from the pollen grain when it comes in contact with stigma of a flower. The male gamete travels from stigma into the style and reaches the female gamete present in the ovary where fertilization takes place.

What happens to the ovule and the ovary after fertilization?

After fertilization, the fertilized ovule forms the seed while the tissues of the ovary become the fruit.

What happens when the pollen tube reaches the ovule?

Once the pollen tube reaches an ovule, it bursts to deliver the two sperm cells. One of the sperm cells fertilizes the egg cell which develops into an embryo, which will become the future plant. … Finally, the ovary will develop into a fruit and the ovules will develop into seeds.

What is the male gamete otherwise known as?

Gametes are an organism’s reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm.

What happens to the pollen after it reaches the stigma?

When a pollen grain lands on the stigma of a flower of the correct species , a pollen tube begins to grow. It grows through the style until it reaches an ovule inside the ovary. The nucleus of the pollen then passes along the pollen tube and fuses (joins) with the nucleus of the ovule.

What happens to the petals after fertilization?

After fertilization, petals fall off. Petals are the most colourfull or brightly coloured part of a flower and they play an essential role by attracting pollinators for pollination and protect the ovary. Thus once after the fertilization, petals fall off.

How do male gametes produce pollen grains?

In the pollen grains, the germ cells divide. This releases two sperm cells that move down the pollen tube. One meiosis gives rise to four pollen grains. Each of these pollen grain gives rise to 2 male gametes.

What is the fate of male gamete?

->Helobial endosperm- In this, the first division of primary endosperm nucleus is followed by cytokinesis to produce two unequal sizes of cells. So the correct answer is that – the fate of the male gametes discharged in the synergid is that one fuses with the egg, other fuses with central cell nuclei.

What are the male gametes in plants?

The male gametes of angiosperms consist of two sperm cells within a pollen grain or a pollen tube. They are derived from a single generative cell, which is formed as the smaller cell by unequal cell division in the microspore after meiosis.

What will happen after male gamete fuses with the female gamete inside the ovary of the flower?

Ultimately, one sperm cell fuses with the egg cell and the other one fuses with the central cell, producing an embryo and an endosperm, respectively. Fertilization in which 2 sets of gamete fusion events occur, called double fertilization, has been known for over 100 y.

When a male gamete fuses with a female gamete inside an?

During sexual reproduction, a male and female gamete will merge together to form a new organism. The two haploid cells will fuse together to form a diploid cell called a zygote.
