Answers
the functional unit of life is called cell . it is building block of any living body.
All living organisms have common characteristics, such as feeding, transferring, respiration, excretion, motion, sensation and reproduction. Some living organisms are unicellular, such as bacteria, Amoeba and Paramecium, while most of them are multicellular, such as humans, whales, and trees.
The cell is the tiniest building unit in an organism’s body and is capable of carrying out all the functions of life. Cells vary in shape, structure, and size. There is a relationship between the cell shape and the functions it performs. The nerve cell (neuron) is long in shape in order to transfer the messages from the spinal cord, present inside the vertebral column, to your toes. The muscular cells are cylindrical and long and accumulate together to form muscle fibres. The muscular cells can contract and relax to help the animal move freely.
