The correct answer is protobiont.
Protobiont refers to the accumulation of the organic molecules, enveloped by a membrane, which abiotically unites into the resemblances of living matter, and are considered to be the precursors of prokaryotic cells.
The scientists consider that protobionts are the evolutionary precursors of the prokaryotic cells. They would have generated as an arrangement of microspheres of different inorganic and organic compounds surrounded by lipidic membranes. According to the scientists, RNA was the nucleic acid of the primitive protobionts.
Answer:
Option C, zygote
Explanation:
The complete question is
The cell produced by the fusion of an egg and a sperm is the
a. gamete
b. oocyte
c. zygote
d. germ line cells
e. somatic cell
Solution
During the process of fertilization in sexual reproduction, when a male gamete (sperm) and female gamete (egg) fuses they form a new cell known as zygote.
Both male and female gamete are haploid with”n” number of chromosomes (only a single set of genes) and when they combine they form diploid zygote with “2n” number of chromosomes.
Hence, option C is correct
