Photosynthesis and Energy Sources

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 (a sugar) and oxygen.

Front

What role do chloroplasts play in photosynthesis?

Back

Chloroplasts are organelles in plant cells that contain chlorophyll and are the site of photosynthesis.

Front

What is the function of stomata in plants?

Back

Stomata are tiny pores on the underside of leaves that allow for gas exchange, enabling the intake of carbon dioxide and the release of oxygen.

Front

What are autotrophs?

Back

Autotrophs are organisms that produce their own food from inorganic substances, primarily through photosynthesis.

Front

What are heterotrophs?

Back

Heterotrophs are organisms that cannot produce their own food and must consume other organisms for energy.

Front

What is the role of water in photosynthesis?

Back

Water is absorbed by plant roots and is essential for photosynthesis, providing electrons and protons needed for the conversion of light energy.

Front

What is the significance of light in photosynthesis?

Back

Light provides the energy required for photosynthesis, driving the reactions that convert carbon dioxide and water into glucose.

Front

What is a carnivore?

Back

A carnivore is an organism that primarily eats other animals.

Front

What is a decomposer?

Back

Decomposers are organisms, such as fungi and bacteria, that break down dead organic matter, returning nutrients to the ecosystem.
