Photosynthesis & Cellular Respiration

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What are autotrophs?

Back

Autotrophs are organisms that produce their own food through photosynthesis or chemosynthesis, such as plants and some bacteria.

Front

What are heterotrophs?

Back

Heterotrophs are organisms that cannot produce their own food and must consume other organisms for energy, such as animals and fungi.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the role of chloroplasts in photosynthesis?

Back

Chloroplasts are organelles in plant cells that capture light energy and convert it into chemical energy during photosynthesis.

Front

What is the equation for photosynthesis?

Back

6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What is the equation for cellular respiration?

Back

C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP.

Front

How do plants and animals depend on each other?

Back

Plants produce oxygen and glucose through photosynthesis, which animals need for cellular respiration, while animals produce carbon dioxide, which plants need for photosynthesis.

Front

What is the significance of glucose in cellular respiration?

Back

Glucose is a primary energy source for cells, and it is broken down during cellular respiration to produce ATP, the energy currency of the cell.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration occurs without oxygen and produces less ATP.
