LT 1.2-1.3 - Photosynthesis

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 reactants of photosynthesis?

Back

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

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (C6H12O6) and oxygen (O2).

Front

What role does sunlight play in photosynthesis?

Back

Sunlight provides the energy needed for photosynthesis to occur, enabling plants to convert carbon dioxide and water into glucose and oxygen.

Front

What is the chemical equation for photosynthesis?

Back

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

Front

What is the significance of chlorophyll in photosynthesis?

Back

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

Front

How do plants obtain carbon dioxide for photosynthesis?

Back

Plants obtain carbon dioxide from the atmosphere through small openings in their leaves called stomata.

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 releases carbon dioxide and water, which are used in photosynthesis.

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.

Front

How does photosynthesis contribute to the oxygen supply on Earth?

Back

Photosynthesis releases oxygen as a byproduct, which is essential for the survival of most living organisms on Earth.
