EL4(H): Cell Energy Flashcard: Photosynthesis

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 are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

Front

What is the role of chloroplasts in photosynthesis?

Back

Chloroplasts are the organelles in plant cells where photosynthesis takes place, containing chlorophyll that captures light energy.

Front

What is glucose and why is it important for plants?

Back

Glucose is a simple sugar produced during photosynthesis that serves as an energy source for plants and is used in cellular respiration.

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 significance of oxygen in photosynthesis?

Back

Oxygen is a byproduct of photosynthesis and is essential for the survival of aerobic organisms, including humans.

Front

What is ATP and its role in cellular energy?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, storing energy in its phosphate bonds for use in various cellular processes.

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.

Front

What is the light-dependent reaction in photosynthesis?

Back

The light-dependent reactions are the first stage of photosynthesis, occurring in the thylakoid membranes of chloroplasts, where light energy is converted into chemical energy (ATP and NADPH).

Front

What is the light-independent reaction (Calvin Cycle) in photosynthesis?

Back

The light-independent reactions, also known as the Calvin Cycle, occur in the stroma of chloroplasts, where ATP and NADPH are used to convert carbon dioxide into glucose.
