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 (C6H12O6) and oxygen (O2).

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in chloroplasts that absorbs light energy, primarily from the blue and red wavelengths, to drive the photosynthesis process.

Front

What are autotrophs?

Back

Autotrophs are organisms that can produce their own food through photosynthesis or chemosynthesis, such as plants and some bacteria.

Front

Where does the light-dependent reaction of photosynthesis occur?

Back

The light-dependent reactions occur in the thylakoid membranes of the chloroplasts.

Front

What is the stroma in a chloroplast?

Back

The stroma is the fluid-filled space inside the chloroplast where the light-independent reactions (Calvin cycle) take place.

Front

What is the significance of ATP in photosynthesis?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, produced during the light-dependent reactions and used in the light-independent reactions to synthesize glucose.

Front

How do high temperatures affect photosynthesis?

Back

High temperatures can slow down photosynthesis because they can denature enzymes involved in the process.

Front

What color of light is most effectively absorbed by plants?

Back

Plants primarily absorb red light for photosynthesis.

Front

What is the Calvin cycle?

Back

The Calvin cycle is the series of biochemical reactions that occur in the stroma of chloroplasts during photosynthesis, where carbon dioxide is converted into glucose.
