photosynthesis and respiration

Front

What is photosynthesis?

Back

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

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in the chloroplasts of plants that absorbs light energy, primarily from the sun, which is essential for the process of photosynthesis.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (C6H12O6) and oxygen (O2).

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

How are photosynthesis and respiration related?

Back

Photosynthesis produces glucose and oxygen, which are used in cellular respiration to produce energy, while respiration releases carbon dioxide and water, which are used in photosynthesis.

Front

What is the equation for photosynthesis?

Back

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

Front

What is the equation for cellular respiration?

Back

The equation for cellular respiration is: C6H12O6 + 6O2 → 6CO2 + 6H2O + energy (ATP).

Front

What factors affect the rate of photosynthesis?

Back

The rate of photosynthesis is affected by light intensity, carbon dioxide concentration, temperature, and water availability.

Front

Why is the sun considered the primary source of energy for food chains?

Back

The sun is considered the primary source of energy for food chains because it provides the light energy that is converted into chemical energy by producers through photosynthesis.

Front

What is the significance of glucose in plants?

Back

Glucose is significant in plants as it serves as an energy source for growth, development, and cellular respiration, and it is also a building block for other organic compounds.
