Photosynthesis Flashcard

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 and oxygen.

Front

What role does sunlight play in photosynthesis?

Back

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

Front

What are the reactants of photosynthesis?

Back

The reactants of photosynthesis are carbon dioxide, water, and light energy.

Front

Why is oxygen important for living organisms?

Back

Oxygen is essential for respiration in most living organisms, allowing them to convert food into energy.

Front

Who was Joseph Priestley and what did he discover?

Back

Joseph Priestley was an English chemist who discovered that plants produce oxygen, which is essential for animal life, through his experiments.

Front

How do plants obtain carbon dioxide?

Back

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

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 necessary for photosynthesis.

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs, like plants, produce their own food through photosynthesis, while heterotrophs, like animals, obtain energy by consuming other organisms.

Front

What is the equation for photosynthesis?

Back

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