Explain the two ways by which seeds develop without fertilization?
Seeds can develop without fertilization through apomixis, where the embryo is formed without meiosis or fertilization, producing a genetic clone of the parent plant. Another way is through parthenocarpy, where a fruit develops without fertilization, but the seeds within it are not viable.
What fruit grows without fertilization?
Examples of fruits that can grow without fertilization include bananas, pineapples, and figs. These fruits can reproduce through parthenocarpy, a process where fruit develops without seeds or fertilization occurring.
What is partnocarpy?
Parthenocarpy-Set fruit without fertilization
Is the formation of the flower a necessity in fruit production?
Yes, the formation of flowers is generally a necessity for fruit production in flowering plants (angiosperms). Flowers facilitate the process of pollination, which leads to fertilization and the development of seeds. Once seeds are formed, the ovary of the flower typically develops into the fruit, which serves to protect the seeds and aid in their dispersal. However, some plants can produce fruit without fertilization through a process called parthenocarpy, but this is less common.
A large ovary and its seeds are called?
A large ovary and its seeds are called a fruit. The ovary develops into the fruit after fertilization, and the seeds are contained within the fruit.
What were the seed and fruit before fertilization?
Before fertilization, the seed is the ovule and the fruit is the ovary. The ovule contains the female gametophyte and will develop into the seed after fertilization. The ovary contains the ovule and will develop into the fruit after fertilization.
What does the ovary of a flowwer turn into?
The ovary of a flower typically develops into a fruit after fertilization. The ovary walls thicken and mature into the fruit, which contains seeds formed from the fertilized ovules.
Why will the fruit develop after removing the stigma of a flower?
Once the stigma is removed from a flower, it is no longer able to receive pollen for fertilization. Without fertilization, the ovary of the flower will not develop into a fruit. Pollen must be able to reach the stigma for fertilization to occur and for fruit development to take place.
Fleshy structure surrounding the seed in an angiosperm?
The fleshy structure surrounding the seed in an angiosperm is called a fruit. Fruits are formed from the ovary of the flower after fertilization and serve to protect the developing seeds and aid in dispersal. They come in various forms and can be fleshy or dry.
What happens to the ovary wall after fertilization?
The ovary becomes fruit after fertilization.
What the common name used for the ovary of the angiosperm after fertilization?
the ovary after fertilization swells rapidly to form the fruit
What role does double fertilization play in the life cycle of angiosperms?
The fusion of a male gamete with secondary nucleus is called double fertilization and it results in the development of endosperm which nourishes the developing embryo inside the seed. Thus without double fertilization nourishment of developing embryo will be hamphered.
