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 oxygen and glucose.

Front

What is the role of chloroplasts in photosynthesis?

Back

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

Front

What is a heterotroph?

Back

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

Front

What is the significance of oxygen produced during photosynthesis?

Back

Oxygen produced during photosynthesis is essential for the survival of aerobic organisms, including humans, as it is used in cellular respiration.

Front

What happens to water and carbon dioxide during photosynthesis?

Back

During photosynthesis, water and carbon dioxide rearrange to form glucose and oxygen.

Front

What is the carbon cycle?

Back

The carbon cycle is the process through which carbon is exchanged between the atmosphere, land, water, and living organisms.

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs are organisms that produce their own food (e.g., plants), while heterotrophs rely on consuming other organisms for energy.

Front

What is the role of sunlight in photosynthesis?

Back

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

Front

What are fossil fuels in the context of the carbon cycle?

Back

Fossil fuels are carbon reservoirs formed from the remains of ancient plants and animals, taking a long time to form in the carbon cycle.
