BOTANY

Detailed explanation-1: -Ovules are small bead like structures inside the ovary of flower. Ovules contain the female gamete or the egg cell. These structures develop into the seeds after fertilization.

Detailed explanation-2: -In animals, egg cells are also known as ova (singular ovum, from the Latin word ovum meaning ‘egg’). The term ovule in animals is used for the young ovum of an animal. In vertebrates, ova are produced by female gonads (sex glands) called ovaries.

Detailed explanation-3: -Egg cell is the female gamete of plants. It is enclosed in ovule which in turn is present in the ovary of a flower.

Detailed explanation-4: -(b) Zygote is formed inside the ovule.

Detailed explanation-5: -A mature ovule consists of a food tissue covered by one or two future seed coats, known as integuments. A small opening (the micropyle) in the integuments permits the pollen tube to enter and discharge its sperm nuclei into the embryo sac, a large oval cell in which fertilization and development occur.
