Photosynthesis and Cellular Respiration Practice

Front

What is photosynthesis?

Back

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

Front

What is the primary purpose of photosynthesis?

Back

The primary purpose of photosynthesis is to produce sugar (glucose) that plants use as food.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

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

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis produces glucose and oxygen, which are used in cellular respiration to produce energy, while cellular respiration releases carbon dioxide and water, which are used in photosynthesis.

Front

What role do guard cells play in plants?

Back

Guard cells are specialized cells in plant leaves that regulate water loss and gas exchange by opening and closing the stomata.

Front

What does digestion mean in the context of biology?

Back

Digestion refers to the process of breaking down macromolecules into their building blocks.

Front

What does synthesis mean in biological terms?

Back

Synthesis is the process of using building blocks to make macromolecules.

Front

What are macromolecules?

Back

Macromolecules are large, complex molecules that are essential for life, including carbohydrates, proteins, lipids, and nucleic acids.

Front

What is the role of chlorophyll in photosynthesis?

Back

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