Fun Facts

  • Cytoplasm is the jelly-like liquid inside the cell where the organelles are found.
  • A vacuole is an organelle where fluids and other nutrients are stored for the cell. It is like a reservoir.
  • Lysosomes are organelles that act as the cell's trash and recycling center.

Why Do We Need To Know About Organelle

Learning about organelles helps us understand how cells work, which is important for many science jobs. For example, doctors who study diseases look at cells, and scientists who study life’s tiny parts focus on organelles.

Knowing about organelles, such as the mitochondria that change sugar into energy, is key for making new medical treatments and things like lab-grown meat. This shows how studying cells affects health, food, and how we live.

Frequently Asked Questions

What is the difference between a unicellular organism and a multicellular organism?
Single celled organisms are made up of only one cell. An amoeba is an example of a unicellular organism. Multicellular organisms are made up of more than one cell. People, dogs and plants are all examples of multicellular organisms.
Why is the mitochondria of a cell important?
The mitochondria is where sugar is converted into energy. The cell needs energy in order to carry out its everyday functions.
What function does a cell wall serve for a plant?
The cell wall gives a plant cell support and structure allowing the plant to stand upright. This is important so that the plant can get sunlight in order to do photosynthesis.
