Detailed explanation-1: -The nucleus is the most conspicuous organelle found in a eukaryotic cell. It houses the cell’s chromosomes and is the place where almost all DNA replication and RNA synthesis occurs. The nucleus is spheroid in shape and separated from the cytoplasm by a membrane called the nuclear envelope.

Detailed explanation-2: -The spherical structure organelle that contains the genetic material is the nucleus.

Detailed explanation-3: -The nucleolus is the spherical body present at the centre of the nucleus. The function of nucleoplasm is to produce and assemble the cell’s ribosomes.

Detailed explanation-4: -Mitochondria are spherical or rod-shaped and double membranous structures present in all cells. Mitochondria are considered as powerhouse of cells because they produce cellular energy in the form of ATP.

Detailed explanation-5: -The nucleus (Figure 6) serves as the cell’s command center, sending directions to the cell to grow, mature, divide, or die. It also houses DNA (deoxyribonucleic acid), the cell’ s hereditary material.
