Matter Cycling & Photosynthesis

Front

What is matter cycling?

Back

Matter cycling refers to the process by which essential elements and compounds are recycled in ecosystems, including the movement of carbon, nitrogen, and water.

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.

What is the role of stomata in plants?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange; they enable carbon dioxide to enter the leaf and oxygen to exit.

Front

How do plants absorb water?

Back

Plants absorb water through their roots, which then travels up the stem to the leaves.

Front

What is the primary source of energy for photosynthesis?

Back

The primary source of energy for photosynthesis is sunlight.

Front

Where does photosynthesis occur in plants?

Back

Photosynthesis occurs primarily in the leaves of plants, specifically in the chloroplasts.

Front

What are the reactants of photosynthesis?

Back

The reactants of photosynthesis are carbon dioxide (CO2) and water (H2O).

Front

What is glucose and its role in photosynthesis?

Back

Glucose (C6H12O6) is a product of photosynthesis that serves as an energy source for plants and is used in cellular respiration.

Front

What is the significance of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that captures light energy for photosynthesis.

Front

What is the equation for photosynthesis?

Back

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