Question

___________is considered as the biggest cell.

Answer 1

Hint: The cell is the smallest and basic structural unit of life. The cell has many cellular components that help it to survive in various situations. The cell also contains the hereditary structure that allows it to replicate it.

Complete answer:
The cell is the smallest and basic structural unit of life. The cell's mainly membrane-bound structure within it contains protoplasm (cytoplasm + nucleus) and the cellular components that help the cell to function properly and can remain in various situations. The cell is mainly consisting of proteins, carbohydrates, lipids and nucleic acids that are organic molecules. The prokaryotes (bacteria) have the primitive type of cell and they are unicellular in nature.

Whereas eukaryotes are the multicellular ones in which the cells are grouped to form tissues and further groups of tissues make the organ system that helps the organism to survive. In the unicellular one, the single cell does all its activities within the cell. There are some bacterial cells (unicellular) that can survive the extreme conditions of the environment. So, the biggest cell is the egg which is big up to 15-18 cm. They are creamy or off-white coloured.

Note: In the context of the human body the biggest is the human ovum cell that is about 20 times bigger than the male gamete (sperm). The human ovum is the female gamete carrying a haploid number of chromosomes which is produced by the ovaries and then moves to the fallopian tube for fertilization. If fertilization occurs the human ovum and sperm fuse to form a zygote otherwise a menstrual cycle occurs.
