Detailed explanation-1: -The fruit is the ripened ovary of a plant containing the seeds. After fertilization, the ovary swells and becomes either fleshy or hard and dry to protect the developing seeds. Many fruits help seeds spread (maple seeds). Many things we call vegetables are really fruits such as tomatoes, cucumbers, and beans.

Detailed explanation-2: -The main function of fruit is to disperse and protect the seeds. A fruit contains seeds and many fruits attract animals that feed on them. The fruit also helps in preventing the seeds from getting dry. Fruit also serves as a physical barrier in the process of seed development.

Detailed explanation-3: -The outer covering of a seed is called the seed coat. Seed coats help protect the embryo from injury and also from drying out.

Detailed explanation-4: -Hence, Seed coat, endosperm, and embryo are the three components of a plant seed. The seed coat protects the seed from harm caused by physical, mechanical, temperature, and water.

Detailed explanation-5: -The fruit protects the seeds and also helps to spread them. Many fruits are good to eat and attract small animals, such as birds and squirrels, who like to feed on them. The seeds pass through them unharmed, and then get spread through their droppings.
