The ______ are parts of a mature seed.

1. a. stamen, anther, and pollen grain
2. b. embryo, food reserves, and seed coat
3. c. stigma, style, and ovary
4. d. male and female gametophytes

Introduction: A part of the carpel which carries the female gametes is called the ovule. Ovules undergo fertilization to produce mature seeds. The seeds mainly consist of three parts – an embryo, nutritive tissue or food storage, and the seed covering called as seed coat.

Reason for the correct answer:

The double fertilization that takes place in most of the flowering plants will produce a triploid cell and a zygote. They undergo mitotic division and the triploid cell develops into endosperm while the zygote develops into an embryo sporophyte. During the maturation time of the embryo, the ovules’ integuments will develop into a seed covering called a seed coat. Ovules undergo fertilization to produce mature seeds. The seeds mainly consist of three parts – an embryo, nutritive tissue or food storage, and the seed covering called as seed coat.

The part of a seed which is water-impermeable and covers the seed by providing mechanical support to the seeds is known as seed coat. The seeds also contain reserved food materials in the form of fats, carbohydrates, and proteins. Seeds contain a diploid embryo which will further develop into a zygote.

Option b. is given as “embryo, food reserves, and seed coat”.

The part of a seed which is water-impermeable and covers the seed by providing mechanical support is known as seed coat. The seeds also contain reserved food materials in the form of fats, carbohydrates, and proteins. Seeds contain a diploid embryo which will further develop into a zygote.

Hence, the correct answer is option b...
