Question

3. Who proposed the cell theory? Enlist its postulates.

Answer 1

Schleiden and Schwann both together discussed Schwann’s hypothesis and they formulated cell theory.

The important aspects of cell theory are: 

 ▪ All living organisms are made up of minute units, the cells which are the smallest entities that can be called living. 

▪  Each cell is made up of protoplasm with a nucleus and bounded by plasma membrane with or without a cell wall. 

▪  All cells are basically alike in their structure and metabolic activities. 

▪ Function of an organism is the sum total of activities and interaction of its constituent cells.
