Photosynthesis and Respiration Review

Front

What is the process that plants use sunlight, water, and carbon dioxide to create sugar and oxygen?

Back

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to produce sugar (glucose) and oxygen.

Front

Which organelle is responsible for using sugar and oxygen to produce energy in cells?

Back

The mitochondria are the organelles that use sugar and oxygen to generate energy in the form of ATP (adenosine triphosphate) for the cell.

Front

On average, how many plant cells are there in a typical plant leaf?

Back

A typical plant leaf contains about 20,000 plant cells.

Front

What are the sugar molecules that we obtain from food and are used to store energy?

Back

Carbohydrates are the sugar molecules that we get from food and are used to store energy.

Front

What part of the plant is primarily responsible for photosynthesis?

Back

The leaves of the plant are primarily responsible for photosynthesis.

Front

What is the chemical equation for photosynthesis?

Back

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

Front

What is the role of chlorophyll in photosynthesis?

Back

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

Front

What is cellular respiration?

Back

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

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle).

Front

How do plants obtain carbon dioxide for photosynthesis?

Back

Plants obtain carbon dioxide from the atmosphere through small openings in their leaves called stomata.
