Biology Photosynthesis Review

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 the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (a sugar) and oxygen.

Front

Where does photosynthesis primarily occur in plants?

Back

Photosynthesis primarily occurs in the leaves of plants, specifically in the chloroplasts.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in chloroplasts that absorbs light energy, which is essential for the process of photosynthesis.

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

How do photosynthesis and cellular respiration relate to each other?

Back

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

Front

What is an autotroph?

Back

An autotroph is an organism that produces its own food, typically through photosynthesis, such as plants.

Front

What is a heterotroph?

Back

A heterotroph is an organism that cannot produce its own food and instead obtains it by consuming other organisms.

Front

What is the significance of carbon dioxide in photosynthesis?

Back

Carbon dioxide is a key reactant in photosynthesis; plants absorb CO2 from the atmosphere to produce glucose.

Front

What happens to the color of bromothymol blue (BTB) in the presence of carbon dioxide?

Back

Bromothymol blue turns yellow in the presence of carbon dioxide, indicating an acidic environment.
