Biology Photosynthesis Review

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, and releasing oxygen as a byproduct.

Front

What are the main products of photosynthesis?

Back

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

Front

What is the role of chlorophyll in photosynthesis?

Back

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

Front

Where does photosynthesis primarily occur in plants?

Back

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

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 are photosynthesis and cellular respiration related?

Back

Photosynthesis and cellular respiration are interconnected processes; photosynthesis produces glucose and oxygen, which are used in cellular respiration to produce energy.

Front

What is the equation for photosynthesis?

Back

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

Front

What is the significance of photosynthesis for life on Earth?

Back

Photosynthesis is crucial for life on Earth as it provides the oxygen we breathe and is the foundation of the food chain, supplying energy to plants and, indirectly, to all other organisms.

Front

What factors affect the rate of photosynthesis?

Back

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

Front

What is the role of water in photosynthesis?

Back

Water is a reactant in photosynthesis; it is split into oxygen and hydrogen, providing electrons and protons needed for the formation of glucose.
