Question

Explain the various steps of seed and fruit formation with the help of diagram. Also state that what grows as a seed and fruit after fertilisation?​

Answer 1

Answer:

• the seed is formed by the fertilization of male(pollen grain) and female gament (ovary) . The fusion (double fertilization) between the pollen grain and ovary produces seed .
• Pollen grains are transferred to stigma by various pollinating agents such as water, wind, butterflies, insects, animals, birds, etc. After reaching stigma, the male gametes fuses with the egg in the ovule and forms a zygote. Thus fertilization takes place and so formed zygote divides and develops into an embryo.
• every part of the flower sheds off except ovary. The ovary of the flower develops into the fruit while ovules develop into seeds.

Answer 2

Seed Formation

A seed is formed when fertilised ovule divides by mitosis. It stores food and has the potential to develop into a new plant under optimal conditions.

Following the fertilization, every part of the flower sheds off except ovary. The ovary of the flower develops into the fruit while ovules develop into seeds. The formation of seed completes the process of reproduction in plants. Within the seed, the growing embryo develops and matures.

After fertilisation, the ovary grows into a fruit and other parts of the flower fall off. The fruit is the ripened ovary. The seeds develop from the ovules. The seed contains an embryo enclosed in a protective seed coat.

Fertilization occurs when one of the sperm cells fuses with the egg inside of an ovule. After fertilization occurs, each ovule develops into a seed. Each seed contains a tiny, undeveloped plant called an embryo. The ovary surrounding the ovules develops into a fruit that contains one or more seeds.So, the correct answer is 'Ovule, Ovary'.
