Células: tipos de células

The video tutorial explains the different types of cells, dividing them into three main groups: prokaryotic, eukaryotic, and archaea. Prokaryotic cells, also known as bacteria, lack a nucleus and are often smaller than other cells. They can be harmful or beneficial, with some used in food production. Eukaryotic cells, found in plants and animals, have a nucleus and various cell parts. Archaea cells share features with both prokaryotic and eukaryotic cells and often inhabit extreme environments.

• Some bacteria are used in food production.

What is a key feature of eukaryotic cells?

• They do not have a nucleus.

• They are smaller than prokaryotic cells.

• They are only found in plants.
