Photosynthesis & Respiration

Fun Facts

  • Seaweeds and other algae are part of the kingdom Protista, contain chloroplasts, and are able to photosynthesize.
  • Chloroplasts contain green chlorophyll molecules to absorb sunlight.
  • Oxygen gas bubbles are produced by chloroplasts during photosynthesis.

Why Do We Need To Know About Chloroplast

Learning about chloroplasts helps us understand how plants make their food through photosynthesis and how they turn sunlight into energy. This is important for jobs in science, especially in studying how cells work and how we can use that knowledge to improve our lives.

Also, knowing about chloroplasts can help us find better ways to make renewable energy, like solar power and biofuels. This means we can create energy in cleaner, more efficient ways by copying how plants work.

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.
