Eukaryotic cells have a nucleus enclosed within the nuclear membrane and form large and complex organisms. Protozoa, fungi, plants, and animals all have eukaryotic cells. They are classified under the kingdom Eukaryota.

The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information.

Types of Eukariotic Cells

There are two primary types of eukaryotic cells: animal and plant cells.

A eukaryotic cell has a nuclear membrane. It has mitochondria, Golgi bodies, cell wall. It also contains locomotory organs such as cilia and flagella. The nucleus has a DNA that carries all the genetic information.

Eukaryotic cells are cells of organisms with a well-defined nucleus. They include protists, algae, fungi, plants, and animals.

The origin of eukaryotes is a complex process that has a prokaryotic origin. Although there are several theories that explain this process, according to most studies it is produced by endosymbiosis between several prokaryotic organisms, where the main protoeukaryotic ancestor is of the archaean type and the mitochondria and chloroplasts are of bacterial origin.

Eukaryotic cells can reproduce in three different ways, mainly:

Bipartition: The nucleus divides into two and then the cell divides into two of the same size.
Gemation: The nucleus divides into two, one moves to the membrane and forms a yolk that separates. Forming two cells of different size.
Sporulation: The nucleus divides repeatedly and is surrounded by a membrane forming cells called spores.

Characteristics of Eukaryotic Cells

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.

characteristics of the eukaryotic cell

_{The eukaryotic cell is the basic unit of plant, animal, fungal and protozoan organisms. Those organisms that have eukaryotic-like cells are called eukaryotes.}

The characteristics are

Have a true core
have cellular organelles
Measure between 10 and 100 micrometers
Have genetic material (DNA)
able to divide and reproduce

The eukaryotes developed at least 2.7 billion years ago, following some 1 to 1.5 billion years of prokaryotic evolution.

Cytoplasmic MembraneDescription: It is also called plasma membrane or cell membrane. The plasma membrane is a semi-permeable membrane that separates the inside of a cell from the outside.

Cell Wall

Description: The cell wall is a non-living, rigid structure outside the plasma membrane in plant cells and fungi. It is absent in Eukaryotic cells of animals

Endoplasmic reticulum (ER)

Description: It is a network of small, tubular structures. It divides the space inside of Eukaryotic cells into two parts – luminal (inside ER) and extra-luminal (cytoplasm).

Golgi Apparatus

Description: It is named after the scientist who discovered it, Camillo Golgi. Golgi is made of many flat, disc-shaped structures called cisternae. It is present in all eukaryotic cells except human red blood cells and sieve cells of plants.

Ribosomes

Description: These structures are not bound by a membrane. Ribosomes are also called ‘Protein factories’ since they are the main site of protein synthesis.

Mitochondria
Description: They are membrane-bound organelles, also known as ‘powerhouses of the cell’.

Lysosomes

Description: They are membrane-bound vesicles formed in the Golgi apparatus. Lysosomes are also called ‘suicidal bags’ since they are rich in hydrolytic enzymes such as lipases, proteases, carbohydrates etc. These enzymes are optimally active at acidic pH (less than 7).

Nucleus

Description: Nucleus is the main organelle of a cell. It is a double membrane structure with all the genetic information. Therefore, it is also called the ‘brain’ of a cell. The nucleus is found in all eukaryotic cells except human RBCs and sieve cells of plants.

Cytoskeleton

Description: It is the filamentous network present in the cytoplasm of a cell.

Cilia and Flagella

They are both responsible for the movement of a cell.

Plastids

Description: They are double membrane organelles found in plant cells. They contain pigments and are of three types:

ernesto

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. Eukaryotic cells also contain organelles, including mitochondria (cellular energy exchangers), a Golgi apparatus (secretory device), an endoplasmic reticulum (a canal-like system of membranes within the cell), and lysosomes (digestive apparatus within many cell types). There are several exceptions to this, however; for example, the absence of mitochondria and a nucleus in red blood cells and the lack of mitochondria in the oxymonad Monocercomonoides species.
