What organisms are based on the eukaryotic cell?
Eukaryotes are organisms that range from microscopic single cells, such as picozoans under 3 micrometres across, [7] to animals like the blue whale, weighing up to 190 tonnes and measuring up to 33.6 metres (110 ft) long, [8] or plants like the coast redwood, up to 120 metres (390 ft) tall. [9] .
The ability to maintain different environments inside a single cell allows eukaryotic cells to carry out complex metabolic reactions that prokaryotes cannot. In fact, it’s a big part of the reason why eukaryotic cells can grow to be many times larger than prokaryotic ones.
- 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...
- An 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...
- 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...
- Cell walls not only provide structure, and protect from mechanical damage, they also prevent the cell from bursting as plant cells need to continua...
- Yes. Only eukaryotes have vacuoles.
- Well, from endoplasmic reticulum vesicles are formed and transport things to Golgi apparatus, where it may be modified somehow, sent back to ER or...
- Actually it is surrounded by a double membrane which has 2 phospholipid bilayers each.
- The nucleolus is a region from the nucleus where the different RNAs are found. It is also the site where ribosomes are joined. It´s important to me...
- it is main function is to break down long chains of fatty acids and to detoxify substances, it produces H2O2 as a result, which can be harmful to t...
- 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.
Feb 3, 2023 · How Big are Eukaryotic Cells. Their size is significantly larger than prokaryotic cells, with an average of 10 to 100 µm in diameter. Shapes. The shape of eukaryotic cells varies significantly with the type of cell. Some common shapes include spheroid, ovoid, cuboidal, lenticular, cylindrical, flat, fusiform, discoidal, and polygonal.
Apr 19, 2024 · Eukaryotes are thought to have evolved between about 1.7 billion and 1.9 billion years ago. The earliest known microfossils resembling eukaryotic organisms date to approximately 1.8 billion years ago.

Nov 6, 2020 · Last Updated: November 6, 2020. Definition. 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 more complex than prokaryotic ones because of specialized organelles. Learn how ancient collaborations between cells gave eukaryotes an important energy boost.
Mar 17, 2022 · A eukaryotic cell, or a cell that contains membrane-bound structures, is the basis for every multicellular organism, including animals, plants, and humans as well as some unicellular organisms (organisms with a single cell), such as protozoa.
