Front

What is the primary purpose of photosynthesis?

Back

To create glucose from carbon dioxide and water using sunlight.

Front

What type of respiration occurs without the presence of oxygen?

Back

Anaerobic respiration.

Front

What is fermentation in the context of cellular respiration?

Back

Fermentation is a type of anaerobic respiration that allows cells to produce energy without oxygen.

Front

What do plants absorb through their roots to facilitate photosynthesis?

Back

Water.

Front

Which molecules are primarily broken down by cells to produce energy?

Back

ATP and glucose.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs sunlight, which is essential for converting carbon dioxide and water into glucose.

Front

What are the two main stages of photosynthesis?

Back

Light-dependent reactions and the Calvin cycle (light-independent reactions).

Front

What is the chemical equation for photosynthesis?

Back

6CO2 + 6H2O + light energy -> C6H12O6 + 6O2.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen, while anaerobic respiration does not.

Front

What byproducts are produced during fermentation?

Back

Lactic acid or ethanol and carbon dioxide, depending on the type of fermentation.
