Molecules to Organisms Review

Front

What is the primary function of mitochondria in cells?

Back

Mitochondria are known as the powerhouse of the cell, where cellular respiration occurs to produce energy (ATP) from glucose.

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

Where does photosynthesis take place in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What are autotrophs?

Back

Autotrophs are organisms that can produce their own food from inorganic substances, using light or chemical energy.

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 chemical equation for photosynthesis?

Back

The chemical equation for photosynthesis is: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis produces glucose and oxygen, which are used in cellular respiration to produce energy, while cellular respiration produces carbon dioxide and water, which are used in photosynthesis.

Front

What factors affect the rate of photosynthesis?

Back

The rate of photosynthesis can be affected by light intensity, carbon dioxide concentration, temperature, and the availability of water.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, primarily from the sun, to drive the process of photosynthesis.
