Which is the most important biochemical process in the living world?
Think it through first, then pick an option.
- a Diffusion
- b Osmosis
- c Photosynthesis
- d Transpiration
Answer and explanation
Correct answer: c Photosynthesis
Photosynthesis builds the bridge between sunlight and life, so it is the most important biochemical process.
Why the other options are wrong
- a Diffusion: Diffusion is a physical process, not the most important biochemical process of the living world.
- b Osmosis: Osmosis is a physical process; it is not the source of food for all living things like photosynthesis.
- d Transpiration: Transpiration is the loss of water vapour, not food making.
