Unit 4 - Photosynthesis

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 is chlorophyll?

Back

Chlorophyll is a green pigment found in the chloroplasts of plants that absorbs light energy, primarily from the blue and red wavelengths, and is essential for photosynthesis.

Front

Why do most plants appear green?

Back

Most plants appear green because chlorophyll does not absorb green light; instead, it reflects it.

Front

What is the main function of stomata?

Back

The main function of stomata is to allow gases, such as carbon dioxide and oxygen, to move in and out of the leaves.

Front

What is the chemical formula for glucose?

Back

The chemical formula for glucose is C6H12O6.

Front

Is glucose organic or inorganic?

Back

Glucose is an organic compound.

Front

What factors affect the rate of photosynthesis?

Back

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

Front

What role does light play in photosynthesis?

Back

Light provides the energy needed for photosynthesis to occur, enabling plants to convert carbon dioxide and water into glucose and oxygen.

Front

What are chloroplasts?

Back

Chloroplasts are organelles found in plant cells that contain chlorophyll and are the site of photosynthesis.

Front

What is the equation for photosynthesis?

Back

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