Question

The correct sequences of reproductive stages seen in a flowering plant are -
A. Gametes, zygote, embryo, seedling
B. Zygote, gamete, embryo, seedling
C. Seedling, embryo, zygote, gametes
D. Gametes, embryo, zygote, seedling

Answer 1

Hint: The reproduction is a process by which new offspring or young ones are produced of a similar kind. The male and female parents produce male gametes and female gametes, respectively. These male and female gametes fuse or combine to produce a viable zygote. The new offspring are produced from zygote after growth and development.

Complete answer:
The overall reproduction process can be divided into different stages. The first stage of the reproduction process is the production of gametes. Each individual, either a male or female, separately produces respective gametes by the process of gametogenesis. The male parent produces male gamete, and the female parent produces the female gamete, respectively.

When these gametes come in contact with each other, their fusion will take place and a single diploid cell, the zygote will be formed. This process is called fertilization. After the fertilization, the zygote will start dividing through cell division, and gradually it will be converted into an embryo. Later on, it will produce seeds in plants and young ones in animals. When the seeds get germinated under suitable conditions, it will produce a seedling, the young plant. Thus, the correct order of sequences of reproductive stages will be gamete, zygote, embryo, and finally, seedling.

Hence, the correct answer is option (A).

Note: The reproduction is a fundamental process. It is present of all living organisms. It is found in the unicellular organism as well as in complex multicellular organisms. This process is necessary for the continuity of life. If there will be no reproduction, there will be no life on earth due to lack of living beings.
