Question

Is the invisible movement of molecules necessary for life? Why or why not? Explain.

Answer 1

The movement of various molecules that cannot be visible with naked eye is invisible movement of molecules. Inside living organisms various chemical reactions are taking place continuously like photosynthesis, digestion, transpiration, respiration etc. all these reactions include movements of numerous molecules inside the body. Movement of oxygen and carbon dioxide gas molecules through blood during respiration, breaking down of water molecules in photosynthesis, movement of solute molecules during transportation etc. are examples of movement of invisible molecules inside living organisms which are highly necessary for life.Hence, molecular movement is very necessary for life as it provides energy , transport food and water need for respiration and many more.

Answer 2

These movements are not visible to naked eye, but play a very important role in all the life processes. They are necessary to carry out various metabolic reactions (like respiration,etc) as every body reaction requires movement of molecules and they are necessary for life.
