photosynthesis

What is photosynthesis?

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy, using carbon dioxide and water.

Where does photosynthesis occur?

Photosynthesis primarily occurs in the chloroplasts of plant cells.

What is the primary pigment involved in photosynthesis?

Chlorophyll is the primary pigment that captures light energy for photosynthesis.

What are the raw materials for photosynthesis?

The raw materials are carbon dioxide (CO2), water (H2O), and sunlight.

What are the end products of photosynthesis?

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

What is the overall equation for photosynthesis?

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

What is the significance of photosynthesis?

Photosynthesis is essential for life on Earth as it provides oxygen and organic compounds for food.

What factors affect the rate of photosynthesis?

Light intensity, carbon dioxide concentration, temperature, and water availability affect photosynthesis rates.

How does light intensity affect photosynthesis?

Increased light intensity increases the rate of photosynthesis until a saturation point is reached.

What organisms perform photosynthesis?

Most plants, algae, and certain bacteria, such as cyanobacteria, perform photosynthesis.

What is the significance of chlorophyll in photosynthesis?

Chlorophyll absorbs light energy, primarily in the blue and red wavelengths, driving the photosynthetic process.

How do plants absorb carbon dioxide?

Plants absorb carbon dioxide through small openings called stomata on their leaves.

What is the relationship between photosynthesis and cellular respiration?

Photosynthesis produces glucose and oxygen, which are used in cellular respiration to produce ATP energy.

What role do stomata play in photosynthesis?

Stomata regulate gas exchange, allowing carbon dioxide to enter and oxygen to exit the leaf.

How does temperature affect photosynthesis?

Temperature influences enzyme activity in photosynthesis, with higher temperatures generally increasing rates until a threshold is reached.

What is the role of light in photosynthesis?

Light provides the energy necessary for the conversion of carbon dioxide and water into glucose and oxygen.

What is the outcome of photosynthesis in terms of energy?

Photosynthesis transforms light energy into chemical energy stored in glucose.
