What structural and functional attributes must a cell have to be called a living cell ?

Explanation

All living organisms are made up of cells which form tissue, organ and organ system. So forms constitutional elements of living organisms. Cells possess property of regeneration. It forms new living organism.
Moreover, it forms constitutional unit. That performs definite functions in different parts. It shows division of labour eg. cell organelle show specific character in their functions.
(a) Cell membrane :
Structure : It is made up of phospho lipid.
Function : It shows selective permeability.
(b) Cytoplasm :
Structure : It is a combination mixture of organic, inorganic material fluid.
Function : As a site of metabolism provides material and energy for growth and reproduction.
(c) Nucleus :
Structure : It possesses DNA, nucleus, nuclear membrane, nucleoli, chromatin.
Function : It stores / transports genetic information of cell for reproduction and growth.
(d) Golgi bodies :
Structure : It is a flat, disc like, parallely arranged bags like structure.
Function : If functions as packaging material and for inter cellular transport of synthesized materials.
(e) Endoplasmic Reticulum :
Structure : RER/SER sisterni / tubes / vesicles.
Function: Functions for synthesis of protein and steroid substances.
(f)Mitochondria :
Structure : Double membrane bound structure, inner membrane possesses cristae.
Function : It is a power house of the cell, cellular energy is produced as ATP.
(g) Lysosomes :
Structure : It is a vesicle having single membrane bound layer. It is made up from golgi bodies.
Function : If possesses various types of Hydrolysing enzymes
(h) Vacuoles :
Structure : It is a membrane bound space found in cytoplasm that contains cellular fluids and other materials.
Function : The tonoplast facilitates the transport of a number of ions and other materials against concentration gradients into the vacuole.
