A seed develops from an
- A. ovum
- B. embryo.
- C. ovule
- D. ovary
Introduction:
A seed is defined as an embryonic plant, which is enclosed within a protective covering (seed coat). New plants germinate from the seeds and thus, seeds are an essential part in the reproductive process of plants.
Answer to Problem 1TYU
Correct answer:
Seeds are formed when fertilization takes place in the flowers. The ovules develop into seeds. Therefore, option (C) is correct.
Explanation of Solution
Reasons for the correct statement:
Seeds are also called ripened ovules. This is due to the fact that they are made from ovules after fertilization.
Option (C) is given as “ovule”.
As “seeds are made from ripened ovules”, it is the right answer.
Hence, option (C) is correct.
Reasons for the incorrect statements:
Option (A) is given as “ovum”.
Ovum refers to egg. It is the female sex gamete in oogamous individuals. Eggs do not develop into seeds. So, it is a wrong answer.
Option (B) is given as “embryo”.
An embryo is formed when a zygote (fertilized egg cell) develops. So, it is a wrong answer.
Option (D) is given as “ovary”.
After fertilization, ovary develops into fruit. So, it is a wrong answer.
Hence, options (A), (B), and (D) are incorrect.
Seeds are a result of reproduction. Seeds form when the ovules are fertilized by the male gametes. The ovary develops into the fruit and the ovules develop into seeds. These processes take place post the fertilization event.
