9(B) Photosynthesis vs. Cellular Respiration

Front

What is Photosynthesis?

Back

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

Front

What is Cellular Respiration?

Back

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

Front

What are the main reactants of Photosynthesis?

Back

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

Front

What are the main products of Photosynthesis?

Back

The main products of Photosynthesis are glucose (C6H12O6) and oxygen (O2).

Front

What are the main reactants of Cellular Respiration?

Back

The main reactants of Cellular Respiration are glucose (C6H12O6) and oxygen (O2).

Front

What are the main products of Cellular Respiration?

Back

The main products of Cellular Respiration are carbon dioxide (CO2), water (H2O), and ATP (energy).

Front

Where does Photosynthesis occur in plants?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

Where does Cellular Respiration occur in cells?

Back

Cellular Respiration occurs in the mitochondria of cells.

Front

What is the role of chlorophyll in Photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, which is essential for Photosynthesis.

Front

How does Photosynthesis contribute to the oxygen supply on Earth?

Back

Photosynthesis produces oxygen as a byproduct, which is released into the atmosphere, contributing to the oxygen supply necessary for life.
