In this video, you’ll learn about eukaryotic cells and find the answer to the question you’ve been dying to know your whole life: Do eukaryotic cells have a nucleus, and if so, what is it?

Types of Cells

There are two main types of cells: eukaryotic and prokaryotic.

Eukaryotic cells are more complicated than simple prokaryotic cells, like bacteria. Eukaryotic cells have membrane-bound organelles, while prokaryotic cells do not. Membrane-bound organelles are compartments in a cell with specific functions; they include the nucleus, or the control center of the cell. Eukaryotic cells have a nucleus that contains genetic information called DNA, while prokaryotic cells do not. In prokaryotic cells, the DNA just floats around in the cell.

When we talk about eukaryotic cells, we’re talking about the cells found in animals, humans, and plants. For example, your body has trillions of eukaryotic cells that have a nucleus and share a similar structure. However, each eukaryotic cell is a little different based on its location in the body.

Nucleus

The nucleus is a type of organelle found in eukaryotic cells. As we said earlier, it’s the brain, or control center, of the cell, meaning that it’s in charge of the rest of the organelles. In our example of the group project, the leader would have functioned as the nucleus.The nucleus is surrounded by the nuclear envelope, a membrane that protects the nucleus and its contents, including deoxyribonucleic acid (DNA). DNA carries genetic information that provides the cell with instructions for building molecules. DNA is also the reason why you look like you.

For example, you may have blue eyes like your mom or brown eyes like your dad due to information about eye color carried in the DNA.Nuclear pores allows copies of DNA to exit the nucleus to provide other organelles with directions for building molecules. The long, unconnected strands of DNA in eukaryotic cells are linear rather than circular and occupy the empty space between the nuclear envelope and the nucleolus.

Lesson Summary

Do eukaryotic cells have a nucleus? The answer is yes! Eukaryotic cells have membrane-bound organelles like the nucleus, while prokaryotic cells do not. In eukaryotic cells, the nucleus is the brain of the cell, responsible for protecting the DNA and telling other parts of the cell what to do. The nucleus is surrounded by the nuclear envelope, a membrane that protects the nucleus and its contents, including DNA. DNA carries genetic information, or instructions for building molecules.

Nuclear pores allow copies of DNA to exit the nucleus and provide other organelles with these molecule-building directions. DNA is the reason why you look like you.
