Photosynthesis and Respiration

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What are autotrophs?

Back

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

Front

What are heterotrophs?

Back

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

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is respiration?

Back

Respiration is the biochemical process in which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

Where does respiration occur in cells?

Back

Respiration occurs in the mitochondria of cells.

Front

What are the products of respiration?

Back

The products of respiration are carbon dioxide (CO2), water (H2O), and adenosine triphosphate (ATP).

Front

What are the reactants of photosynthesis?

Back

The reactants of photosynthesis are carbon dioxide (CO2), water (H2O), and sunlight.

Front

How are photosynthesis and respiration interconnected?

Back

Photosynthesis and respiration are interconnected because the products of photosynthesis (glucose and oxygen) are the reactants for respiration, and vice versa.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, used to store and transfer energy for various cellular processes.
