Apr 19, 2024 · Eukaryote, any cell or organism that possesses a clearly defined nucleus. The eukaryotic cell has a nuclear membrane that surrounds the nucleus, in which the well-defined chromosomes (bodies containing the hereditary material) are located. Learn more about eukaryotes in this article.

The eukaryotes (/ j uː ˈ k ær i oʊ t s,-ə t s / yoo-KARR-ee-ohts, -əts) constitute the domain of Eukarya or Eukaryota, organisms whose cells have a membrane-bound nucleus. All animals, plants, fungi, and many unicellular organisms are eukaryotes.
Oct 31, 2023 · Key Points. Eukaryotic cells are larger than prokaryotic cells and have a “true” nucleus, membrane-bound organelles, and rod-shaped chromosomes. The nucleus houses the cell’s DNA and directs the synthesis of proteins and ribosomes.

Overview of eukaryotic cells and how they differ from prokaryotic cells (nucleus, organelles, and linear chromosomes).
What would it be like to live in a one-room cabin? Well, things would probably be pretty simple. You would eat, sleep, work, and relax in a single room—which might be a bit cramped, but would certainly make cleaning the house a snap!
Prokaryotic cells, the simple cells of organisms like bacteria, are sometimes compared to one-room cabins: they don't have internal membranes, so they’re like a single room with no walls to carve it up1 . If we extend this analogy to eukaryotic cells, the more complex cells that make up plants, fungi, and animals, we'll find that they're a definite step upward in the real estate market.
Just as a large family home is split into many rooms with different purposes (bedrooms, bathrooms, kitchen, living room, etc.), so eukaryotic cells contain a variety of different compartments with specialized functions, neatly separated from one another by layers of membrane. This organization lets each compartment maintain its own conditions, the ones it needs to carry out its job.
For instance, compartments called lysosomes, which act as recycling centers for the cell, must maintain an acidic pH in order to dispose of cellular waste. Similarly, structures called peroxisomes carry out chemical reactions called oxidation reactions and produce hydrogen peroxide, both of which would damage the cell if they weren’t safely stored away in their own “room.”
What are the key features of eukaryotic cells? Unlike prokaryotic cells, eukaryotic cells have:
1.A membrane-bound nucleus, a central cavity surrounded by membrane that houses the cell’s genetic material.
2.A number of membrane-bound organelles, compartments with specialized functions that float in the cytosol. (Organelle means “little organ,” and this name reflects that the organelles, like the organs of our body, have unique functions as part of a larger system.)
3.Multiple linear chromosomes, as opposed to the single circular chromosome of a prokaryote.
Eukaryotic cells are much more complicated than those of prokaryotes. They are packed with a fascinating array of subcellular structures that play important roles in energy balance, metabolism, and gene expression.
In the articles and videos that follow, we’ll take a tour through eukaryotic plant and animal cells, exploring the unique structures they contain and the role that each structure plays in the life of the cell.

Characteristics of Eukaryotic Cells. The features of eukaryotic cells are as follows: Eukaryotic cells have the nucleus enclosed within the nuclear membrane. The cell has mitochondria. Flagella and cilia are the locomotory organs in a eukaryotic cell. A cell wall is the outermost layer of the eukaryotic cells.
Eukaryotic cells are characterized by the presence of a nucleus and other specialized organelles that perform different functions. Learn how eukaryotic cells evolved from prokaryotic cells and how they are structured and organized.
