Question

Give examples of $3$ plants that have: many seeded fruits.

Answer 1

Fruits do not all have the same number of seeds. Tomatoes, cucumbers, green peppers, and melons, for example, contain a variety of seeds. Oranges, apples, and pears, on average, produce around $10$ seeds. Avocados, plums, and peaches, for example, contain just one seed.

Complete solution:
Watermelon, kiwi, orange have many seeded fruits. A fruit is the seed-bearing structure produced from the ovary after flowering in flowering plants (also known as angiosperms) in botany.
Angiosperms disseminate seeds with the aid of fruits. Edible fruits, in particular, have spread with the migration of humans and animals in a symbiotic relationship as a means of seed dispersal and nutrition; indeed, humans and certain animals have become reliant on fruits as a food source. As a result, fruits account for a significant portion of global agricultural production, and others (such as the apple and the pomegranate) have taken on significant cultural and symbolic significance.
Every seed is a miniature plant (embryo) with leaves, stems, and root parts that are waiting for the right conditions to germinate and develop. A coat protects the seeds. It is possible for this coat to be thin or dense and rough. The embryo is not well protected by thin coats. Thick coats, on the other hand, may help the embryo survive harsh environments.
The seed also includes endosperm, a short-term food supply that is produced during fertilization but is not part of the embryo. It is used by the embryo to aid in its growth. The endosperm is no longer visible in the bean depicted. It has been used to help the embryo develop.

Note:
Fruits such as apples, bananas, grapes, lemons, oranges, and strawberries are examples of fleshy seed-associated structures of a plant that are sweet or sour and nutritious in their raw form. In botanical terms, however, "apple" refers to a variety of objects that aren't generally referred to as "fruits," such as bean pods, corn kernels, strawberries, and wheat grains. A fruiting body is the part of a fungus that develops spores.
