eukaryote: [noun] any of a domain (Eukarya) or a higher taxonomic group (Eukaryota) above the kingdom that includes organisms composed of one or more cells containing visibly evident nuclei and organelles — compare archaea, bacterium, prokaryote.
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. Eukaryotic cells also contain organelles, including mitochondria (cellular energy exchangers), a Golgi ...

The eukaryotes ( / juːˈkærioʊts, - əts / yoo-KARR-ee-ohts, -əts) [5] 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.

Eukaryotes are organisms whose bodies are made up of eukaryotic cells, such as protists, fungi, plants and animals. Eukaryotic cells are cells that contain a nucleus and organelles, and are enclosed by a plasma membrane. Organisms with eukaryotic cells are grouped into the biological domain Eukaryota (also sometimes called Eukarya). The other two d...
There are four types of eukaryotes: animals, plants, fungi, and protists. Protists are a group of organisms defined as being eukaryotic but not animals, plants, or fungi; this group includes protozoa, slime molds, and some algae. Protists and fungi are usually unicellular, while animals and plants are multicellular. Unicellular eukaryotes can repro...
Eukaryotic cells evolved from prokaryotic cells between 1.6 and 2.7 billion years ago. Today, all complex organisms and most multicellular ones are eukaryotes, making this evolution a major event in the history of life on Earth. There are about 75 separate lineages of eukaryotes, most of which evolved into protists. Eukaryotes are more closely rela...
While eukaryotes are complex, usually multicellular organisms that have eukaryotic cells, prokaryotes are usually single-celled organisms that have simpler prokaryotic cells. Eukaryotes include all complex lifeforms including protozoa, plants, fungi, and animals, while prokaryotes are microscopic, mostly single-celled lifeforms, either archaea or b...
Eukaryotic Cell– a cell that has organelles inside it, including a true nucleus surrounded by a nuclear envelope.Prokaryote– an organism, such as archaea or bacteria, that has prokaryotic cells.Nuclear Envelope– found only in eukaryotic cells, a membrane that separates the nucleus from the cytoplasm (the rest of the cell).Mitochondria– an organelle where cellular respiration takes place and energy is produced.1. Which is a theory of the evolution of mitochondria outlined in this article? A. Free-living bacteria were incorporated into cells. B. Mitochondria were formed from partial infoldings of the cell membrane. C. Mitochondria evolved when an archaeon and a bacterium merged. D.All of the above 2. Which is NOT a characteristic of a eukaryotic cell? A. ...
8 years ago. The Endoplasmic Reticulum in a eukaryotic cell is the transport network of the cell and it extends from and connects the nuclear membrane to the plasma membrane of a cell. But then whenever we draw a diagram of a typical plant or animal cell, we never extend it to the plasma membrane- we always leave it somewhere in the cytoplasm.
- Why are plant cells typically square (if they are) and why do they have a much larger vauole than an...They are squarish because they have a stiff cell wall that forces them into that shape. If you meant vacuole, I think they have a larger vacuole be...
- how come animal cells don't have a cell wallAn animal cell needs to allow mobility for that animal so only has a cell membrane, a plant cell however has a cell wall to give the cell ridged st...
- Why don't plant cells have lysosomes?Plant cells don't have lysosomes, because their cell walls are tough enough to keep out foreign substances that lysosomes would have to digest out...
- In the above diagram the author gives us an example of what a plant cell looks like and I noticed th...Cell walls not only provide structure, and protect from mechanical damage, they also prevent the cell from bursting as plant cells need to continua...

- Does the nucleus have a phospholipid bilayer?Actually it is surrounded by a double membrane which has 2 phospholipid bilayers each.

- I know this isn't really a good question (maybe) but Why are plant cells square and animal cells are...Plant cells have a cell wall that is rigid and defines the cell's shape while animal cells lack a cell wall therefore giving it its circular shape.
Eukaryote definition: any organism of the domain Eukaryota, having as its fundamental structural unit a cell type that contains specialized organelles in the cytoplasm, a membrane-bound nucleus enclosing genetic material organized into chromosomes, and an elaborate system of division by mitosis or meiosis, characteristic of all life forms except bacteria and other primitive microorganisms..
Nov 6, 2020 · A eukaryotic cell contains membrane-bound organelles such as a nucleus, mitochondria, and an endoplasmic reticulum. Organisms based on the eukaryotic cell include protozoa, fungi, plants, and animals. These organisms are grouped into the biological domain Eukaryota. Eukaryotic cells are larger and more complex than prokaryotic cells found in ...
