"When different parts of a organism work together in unison, things can be accomplished that could not happen otherwise." Explain this statement ,using the interactions between different parts of the cell, tissues, and organs to support your answer.

The cell is the specialized smallest unit which forms tissues and eventually organ system and a full organism explains the statement.

Explanation:

Cell is the basic structural and functional unit of life. All life originates from the cells and group of cells.

Cell has a full equipped machinery which is capable of growth and performing independent  function. The specialized cell arising from the zygote by totipotency will direct the formation of tissues which will club to form specialized organs followed by a full organism.

The specialised cell as nephrons in kidney, gametes in sex organs, neuron in brain, cardiac cells in heart, fundic cells in stomach, udder cells in mammary gland, rods and cone cells in eyes etc.

Baby born with full-grown specialized organs will have growth by the process of mitosis in the cells which will ensure growth and repair of the cells and eventually the organs and the organisms. Cells of various organs communicate via cell signalling and are in unison in performance.

It can be concluded that two single cells give rise to full organism in which all the organs are working in unision as a system.
