Photosynthesis and Respiration

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy, using carbon dioxide and water to produce glucose and oxygen.

Front

What is respiration?

Back

Respiration is the process by which living organisms convert glucose and oxygen into energy, producing carbon dioxide and water as byproducts.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy, primarily from the sun, to facilitate photosynthesis.

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 cyanobacteria in the history of photosynthesis?

Back

Cyanobacteria are among the first organisms to perform photosynthesis, contributing to the oxygenation of the Earth's atmosphere.

Front

What is a chemical reaction?

Back

A chemical reaction is a process in which reactants are transformed into products, involving the breaking and forming of chemical bonds.

Front

What are the two types of respiration?

Back

The two types of respiration are aerobic respiration (which requires oxygen) and anaerobic respiration (which does not require oxygen).

Front

What is the role of mitochondria in respiration?

Back

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

Front

What is the relationship between photosynthesis and respiration?

Back

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