10-15 Facts about cells

1. Animal cells do not have a cell wall.

The cell wall in plant cells helps give the cell shape and protection.

2. Mitochondria is the powerhouse of the cell.

The mitochondria gives directions to other organelles. They also create ATP, which gives energy to the cell.

3. The nucleus is the largest organelle in animal cells.

The largest organelle in plant cells is the vacuole, which usually takes up most of its volume. The vacuoles in animal cells are not as big.

4. In plant cells, chloroplast absorbs the sun for photosynthesis.

Chloroplast is very important for plant cells, as photosynthesis is a vital part of survival. It uses the light energy from the sun to create energy.

5. Cells are the smallest unit of life.

Not to be confused with atoms, which are the smallest unit of matter, cells are the smallest unit of life.

6. Humans are made of eukaryotic cells.

Eukaryotic cells are usually animal cells, while prokaryotic cells are usually things like bacteria. Humans are animals.

7. The ribosomes take directions from the nucleus for protein synthesis.

As stated above, the mitochondria will give directions to the organelles, one of them being the ribosomes. They will then use these directions to do protein synthesis.

8. Cells have both DNA and RNA.

DNA will most likely be found in the nucleus of a cell, while RNA will probably be located in the cytoplasm.

9. Prokaryotes do not have a nucleus, along with other organelles.

Prokaryotes do not have membrane-bound organelles, this includes the nucleus.

10. One job that lysosomes have is breaking down macromolecules.

While breaking down macromolecules is one job of lysosomes, they also do things like repair the cell membrane.
