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

Why do most plants appear green?

Back

Most plants appear green because chlorophyll reflects green light.

Front

What do plants need for photosynthesis?

Back

Plants need sunlight, carbon dioxide, and water for photosynthesis.

Front

What is chlorophyll?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy for photosynthesis.

Front

What is an autotroph?

Back

An autotroph is an organism that can produce its own food using light or chemical energy, such as plants.

Front

What is a heterotroph?

Back

A heterotroph is an organism that cannot produce its own food and must consume other organisms for energy.

Front

Where does the Calvin cycle take place?

Back

The Calvin cycle takes place in the stroma of chloroplasts.

Front

What is the role of sunlight in photosynthesis?

Back

Sunlight provides the energy needed for plants to convert carbon dioxide and water into glucose.

Front

What are high-energy sugars?

Back

High-energy sugars are carbohydrates produced during photosynthesis that serve as energy sources for plants.

Front

What happens if carbon dioxide is removed from a plant's environment?

Back

If carbon dioxide is removed, the plant will not be able to produce sugars, and photosynthesis will stop.
