6.L.1.2 - Photosynthesis/Respiration/Transpiration

Front

What is photosynthesis?

Back

The process by which green plants use sunlight to synthesize foods with the help of chlorophyll, converting carbon dioxide and water into glucose and oxygen.

Front

What is cellular respiration?

Back

The process by which cells break down glucose and oxygen to produce energy, carbon dioxide, and water.

Front

What is transpiration?

Back

The process of water movement through a plant and its evaporation from aerial parts, especially from the leaves.

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 + energy (ATP).

Front

What role do guard cells play in plants?

Back

Guard cells control the opening and closing of stomata, regulating gas exchange and water loss.

Front

What are stomata?

Back

Small openings on the surface of leaves that allow for gas exchange (CO2 in, O2 out) and transpiration.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, primarily from the sun, to drive photosynthesis.

Front

What gas do plants take in during photosynthesis?

Back

Carbon dioxide (CO2).

Front

What gas do plants release during photosynthesis?

Back

Oxygen (O2).
