Detailed explanation-1: -The cell is the smallest structural and functional unit of living organisms, which can exist on its own. Therefore, it is sometimes called the building block of life. Some organisms, such as bacteria or yeast, are unicellular-consisting only of a single cell-while others, for instance, mammalians, are multicellular.

Detailed explanation-2: -Cells are the smallest common denominator of life. Some cells are organisms unto themselves; others are part of multicellular organisms.

Detailed explanation-3: -Cells are the basic structural and functional unit of life as they are the smallest unit that can be called living. One complete cell is capable of performing all the physiological activities. Cells combine to form tissues, which are a collection of cells performing a similar function.

Detailed explanation-4: -The simplest, smallest unit of matter is the atom. Atoms bond together to form molecules, and molecules come together to form cells, the smallest unit of life. Cells group together to form tissues, such as muscle, or intestine.
