Photosynthesis & Cellular Respiration SLT 2025-26

Front

What molecule absorbs sunlight for photosynthesis?

Back

Chlorophyll is the molecule that absorbs sunlight, allowing plants to convert light energy into chemical energy.

Front

What are light-absorbing molecules in plants called?

Back

Pigments are the light-absorbing molecules in plants that capture sunlight for photosynthesis.

Front

What effect does increasing light intensity have on photosynthesis?

Back

Increasing light intensity generally speeds up the rate of photosynthesis, up to a certain point.

Front

What process occurs in yeast cells when oxygen is not present?

Back

Alcoholic fermentation occurs in yeast cells in the absence of oxygen, allowing them to produce energy.

Front

What gas is released by plants during photosynthesis?

Back

Oxygen is the gas released by plants as a byproduct of photosynthesis.

Front

What is the primary function of chloroplasts in plant cells?

Back

Chloroplasts are organelles that conduct photosynthesis, converting light energy into chemical energy.

Front

What is the role of thylakoids in photosynthesis?

Back

Thylakoids are membrane-bound structures within chloroplasts where the light-dependent reactions of photosynthesis occur.

Front

What is the overall equation for photosynthesis?

Back

The overall equation for photosynthesis is 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What is cellular respiration?

Back

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

Front

What are the two main types of cellular respiration?

Back

The two main types of cellular respiration are aerobic respiration (with oxygen) and anaerobic respiration (without oxygen).
