Photosynthesis and Cellular Respiration

Front

What is photosynthesis?

Back

The process by which plants and other autotrophs capture and use light energy to make food from carbon dioxide and water.

Front

What is an autotroph?

Back

An organism that is able to capture energy from the sun and use it to produce its own food.

Front

What role do autotrophs play in an ecosystem?

Back

Autotrophs are producers, meaning they create their own food and serve as a food source for other organisms.

Front

What is the chemical equation for photosynthesis?

Back

CO2 + H2O + Light energy → C6H12O6 + O2

Front

What is cellular respiration?

Back

The process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

Front

What is fermentation?

Back

A process that releases a smaller amount of energy than cellular respiration, often occurring in the absence of oxygen.

Front

What are heterotrophs?

Back

Organisms that cannot produce their own food and must consume other organisms for energy.

Front

What is the main product of photosynthesis?

Back

Glucose (C6H12O6), which is used by plants for energy.

Front

What is the significance of oxygen in photosynthesis?

Back

Oxygen is released as a byproduct of photosynthesis and is essential for the survival of aerobic organisms.

Front

How do plants obtain carbon dioxide for photosynthesis?

Back

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