Question

what are the significance of cell respiration and photsynthesis to life on earth

Answer 1

Photosynthesis and cellular respiration are the two main processes performed by most living organisms to obtain usable energy from nature. While photosynthesis is performed by most plants who can prepare their own food, most animals fulfill their energy requirements through cellular respiration.

Differences

Photosynthesis utilizes sunlight to produce food molecules.
Cellular respiration utilizes glucose molecules to obtain energy-storing ATP molecules.

☛ Photosynthesis takes place in plant leaves containing the chlorophyll pigment.
☞ Cellular respiration takes place in the cytoplasm and mitochondria of the cell.

☛ Photosynthesis uses water, sunlight, and CO2 from the atmosphere to create glucose molecules, and releases oxygen as a by-product.
☞ Cellular respiration uses glucose molecules and oxygen to produce ATP molecules and CO2 as the by-product.

☛ Photosynthesis takes place only when there is sunlight.
☞ Cellular respiration occurs at all times.

☛ Photosynthesis involves conversion of one type of energy into another: light energy into chemical energy.
☞ Cellular respiration involves using that chemical energy and breaking it down to release energy.

☛ Photosynthesis takes place in two stages of light reactions and dark reactions.
☞ Cellular respiration involves aerobic (glycolysis) and anaerobic respiration.

☛ Photosynthesis occurs only in plants and some bacteria.
☞ Cellular respiration takes place in all types of living organisms.
