Photosynthesis & Respiration

Fun Facts

  • Both plants and animals go through cellular respiration to use stored energy.
  • When trees lose their leaves, they go through cellular respiration to use their stored energy to stay alive.
  • Occurs in the mitochondria, known as the powerhouse of the cell.

Why Do We Need To Know About Cellular Respiration

Learning about cellular respiration helps you know how living things make and use energy. This is important for science and making green energy sources.

Cellular respiration is a key life process and helps scientists make better biofuels and solar panels. This work helps people in renewable energy, helping the environment, and studying tiny life parts, showing how important biology is in real life.

Frequently Asked Questions

What is the process of photosynthesis?
Photosynthesis is the chemical process in which plants and other organisms combine carbon dioxide and water, using energy from the Sun, to produce sugar and oxygen.
What is the process of cellular respiration?
Cellular respiration is the chemical process that occurs when an organism breaks down the food it has stored (sugars and fats) and uses it for energy.
Besides plants, what are examples of other organisms that use photosynthesis?
Some bacteria, such as cyanobacteria, go through photosynthesis and so do algae.
