Answer:
1. c). gametes.
2). oocyte
3). diploid.
Explanation:
1. Gamete is defined as a haploid reproductive cell, that fuse with another reproductive cell of opposite sex during sexual reproduction. The male gamete is known as sperm and the female gamete is known as egg that fuse together to form a zygote.
Thus, the correct answer is option (c).
2. An oocyte can be defined as a female germ cell or reproductive that that forms female gamete or egg cell. Oocyte is an immature egg cell that has not finished meiotic division and forms mature egg cells after completing meiosis.
Thus, the correct answer is option (d).
3. A diploid cell can be defined as a cell having two complete sets of chromosomes. Diploid number of chromosomes is represented by 2n, where n shows haploid chromosome number.
For example, somatic cells of humans are diploid cells as they contain 46 chromosomes (23 pairs of chromosomes).
Thus, the correct answer is option (c).
