There and many protists are made of eukaryotic

There are two types of cells: eukaryotic and prokaryotic. We humans are made of eukaryotic cells because our cells have a nucleus. Let’s learn more about what makes a eukaryotic cell different.

What Is a Eukaryotic Cell?

Did you know that you are made out of cells? Cells are the smallest part of all living things that maintains the characteristics of its organism. There are two main types of cells: eukaryotic and prokaryotic. Animals, plants, fungi, and protists all are made of eukaryotic cells, which are cells that have a nucleus, a protective membrane around the nucleus, and special structures called organelles.We humans – and all other animals – are made of eukaryotic cells.

Let’s shrink down and take a look at the eukaryotic animal cell up close!

Parts of a Eukaryotic Cell

The first difference we’ll notice about a eukaryotic cell is how big it is! Eukaryotic cells are much larger than prokaryotic cells. Maybe it is because of all the parts they need to hold. These cell parts are the organelles, and only eukaryotic cells are the only cells that have organelles. Let’s go to the cell to explore what parts we can find.

See the large organelle with the black dot in the middle? That is the nucleus.

You won’t find a nucleus in a prokaryotic cell.The nucleus is the control center of the cell and holds all of the DNA. You may find it hard to move around inside the cell, because there are so many other organelles in here. Some of them include the mitochondria, vacuoles, and ribosomes.

Single-Celled Eukaryotes

Some living things are only one cell big! They are called single-celled. Protists, for instance, make up a diverse group of since-celled organisms, many of which are made of a eukaryotic cell, including algae and amoebas.

These single-celled eukaryotic organisms can do some interesting things, like move on their own.

In this image, you can see a part that looks like a tail coming out of the cell. That is called a flagella. Other single-celled eukaryotes have little hairs all over them that can row like oars for a canoe. This helps the cell move around.

Examples of Eukaryotic Cells

We know that humans and many protists are made of eukaryotic cells, but there are many more living things that are made of eukaryotic cells. These include:

  • Animals: All animals, including mammals, birds, reptiles, amphibians, fish, and more, are made of eukaryotic cells.
  • Plants: All plants, including trees, flowers, and ferns, are made of these kind of cells, too.
  • Even types of fungus are eukaryotic, like yeast, mushrooms, mold, and more.

Lesson Summary

All living things are made of one of two types of cells: eukaryotic or prokaryotic.

Eukaryotic cells have many organelles inside of them, most importantly the nucleus. Animals, plants, fungi, and protists all have eukaryotic cells.
