A cell is defined as the structural and functional unit of an organism.
The average size of the prokaryotic cell lies between 0.1 to 10 micrometers whereas the average size of the eukaryotic cell is approximately 25 micrometers.
Four things are found in all the cells: genetic material (either DNA or RNA), cell membrane, cytoplasm, and the ribosome.
All the living cells grow and reproduce (sexually or asexually) and have the ability to respond to stimuli.
Thus, characteristics of a cell may include: cell grows and reproduces, responds to stimuli, contains DNA or RNA, not both , and contains a cell membrane.

Essay on types of digestion
Explanation:
Digestion refers to the breakdown of large food molecules into small food molecules so that can be absorbed by the blood. There are two types of digestion i. e. mechanical digestion and chemical digestion. in mechanical digestion, the food is broken down into smaller parts physically with the help of teeth while on the other hand, in chemical digestion, food is broken down into small particles with the help of chemicals such as acids and enzymes. This chemical digestion is carried out in the stomach where different types of chemicals are present.
