Trimester exam review 2

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 cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

How do photosynthesis and cellular respiration cycle matter?

Back

The outputs of photosynthesis (glucose and oxygen) are the inputs for cellular respiration, while the outputs of cellular respiration (carbon dioxide and water) are the inputs for photosynthesis.

Front

What is the relationship between light distance and the rate of photosynthesis?

Back

The less distance between the light and the algae, the greater the rate of photosynthesis.

Front

What energy source do plants use for photosynthesis?

Back

Plants get the energy they need for photosynthesis from sunlight.

Front

What is the correct equation for photosynthesis?

Back

6CO₂ + 6H₂O → 6O₂ + C₆H₁₂O₆

Front

Which gas is removed from the atmosphere during photosynthesis?

Back

Carbon dioxide is removed from the atmosphere during photosynthesis.

Front

What role does chlorophyll play in photosynthesis?

Back

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

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

Front

What is the significance of photosynthesis in the ecosystem?

Back

Photosynthesis is crucial for life on Earth as it produces oxygen and organic compounds that serve as food for most living organisms.
