|
|
the smallest structural and functional unit of an organism.

|
|
a spherical shaped organelle. It is the brain or the command centre of the cell. It regulates the integrity of genes and gene expression and is also responsible for the protein synthesis, cell division, growth and differentiation.

Detailed explanation-1: -Mitochondria are spherical or rod-shaped and double membranous structures present in all cells.
Detailed explanation-2: -The nucleus is a small, round and membrane-bound structure found in cells. And the fluid inside the nucleus surrounded by the nuclear membrane is called nucleoplasm. It controls cell’s growth and reproduction as it contains cell’s hereditary information. It’s covered by dual layer called a nuclear membrane.
Detailed explanation-3: -A nucleus, as related to genomics, is the membrane-enclosed organelle within a cell that contains the chromosomes. An array of holes, or pores, in the nuclear membrane allows for the selective passage of certain molecules (such as proteins and nucleic acids) into and out of the nucleus.
Detailed explanation-4: -The nucleolus is the spherical body present at the centre of the nucleus.
