Question:

Is there a direct relationship between the number of ovules in an ovary and the number of seeds in a fruit?

Options:

Yes, the number of ovules and seeds is always the same

No, the number of ovules and seeds can vary in a fruit.

Only true fruits have a relationship between ovules and seeds

False fruits do not contain any seeds

Correct Answer:

No, the number of ovules and seeds can vary in a fruit.

Explanation:

The answer is (b). No, the number of ovules and seeds can vary in a fruit.

The number of ovules in an ovary is determined by the plant's genetics. However, the number of seeds that actually develop in a fruit can be affected by a number of factors, including pollination, fertilization, and seed development.

The number of ovules in an ovary does not necessarily determine the number of seeds in a fruit. While each ovule has the potential to develop into a seed, not all ovules are fertilized and develop into viable seeds. Various factors can influence the fertilization and development of ovules, such as pollination success, availability of pollen, and other environmental conditions. Additionally, some fruits may develop without fertilization or may have unfertilized ovules, resulting in seedless fruits. Therefore, the number of seeds in a fruit can vary and is not directly linked to the number of ovules in the ovary.

Option c  is not entirely accurate because the relationship between ovules and seeds applies to true fruits as well as false fruits.

Option d .False fruits, such as apples or strawberries, develop from structures other than the ovary, but they can still contain seeds.
