What happens to the plant after fertilization?


What happens in the plant after fertilization?

As a result of the events of pollination and fertilization, a zygote is formed in the ovum of the seed in the ovary of the female organ. The formed zygote develops by dividing continuously and forms the outline of the plant called the embryo. After the embryo is formed, a protective shell forms around it and food is stored inside the shell.

What happens before and after the development of the flower?

The mandibles absorb nutrients from the endosperm during seed development and transmit them to the embryo during germination. After fertilization, the egg turns into a seed, while the ovary develops into a fruit. The simple fruit is formed by the development of a single ovary of a flower.

Where does fertilization take place in the flower?

The male reproductive organ in plants produces pollen. These pollens pass from one flower to another due to the effect of the human hand, the wind and insects such as bees. Pollination occurs when the female reaches the stigma of the reproductive organ. Pollination descends from the stigma at the ovary, where fertilization takes place.

How does the life cycle of the plant begin?

B) Life cycle of plants 1. Seed: it is dormant when there is sufficient humidity and temperature. The plant kicks in and breaks the bark. 2. Germination: the root begins to stick to the ground and a small shoot begins to rise towards the light. 3. Adult plant: the plant develops, grows and begins to produce its own food.

Where is pollen produced?

They are green in color and look like leaves. The threads connect the male organ to the flower. The anther sacs produce pollen.

Where do sperm nuclei form?

Male and female cones are found on different parts of the same plant. Male cones are not very large even in adulthood. In the pollen produced by male cones, the vegetative nucleus forms the pollen tube and the generative nucleus forms the spermatic nuclei.

What structure takes place in the plant? It’s called sticking to the stigma. Therefore, the pollen attached to the stigma descends from the stigma at the ovary and fertilization occurs. The fertilized egg is called a zygote.

What is it called when the male and female organs are mature at the same time?

Self-pollination is the pollination of female organs with pollen of the same species. Pollination of the variety with pollen is called “foreign pollination”. The maturation of the male and female organs at the same time is called “Homogamy”, and the maturation at different times is called “Dicogamy”.
