Question 22

What is the comparison between photosynthesis and respiration

Answer 22

P - Only takes place in plants
R - Takes place in plants and animals

P - Oxygen and sugar are formed during the process
R - Water and carbon dioxide are formed during this process

P - Photosynthesis needs sunlight
R - Respiration does not need light

P - Food is produced
R - Food is broken down

P - Energy is stored
R - Energy is released

P - Only takes place in cell that contain chlorophyll
R - Takes place in all living cells

P - An anabolic (constructive) metabolic process
R - A catabolic (destructive) metabolic process
