What is eukaryote?

eukaryote is a type of cell (or unicellular organism) that has organelles bound to the membrane, unlike the prokaryotes (bacteria and archaea), which is not. eukaryote means a "good/right walnut/core" in Greek, referring to the core, while "Prokaryote" means "before walnut/core". Eukaryote cells tend to be larger (probably) and much more complicated than prokaryote cells.

All plants, animals, mushrooms and many microorganisms are eukaryotes. Eukaryotic cells have numerous organelles or cell partial units with designated roles. These include mitochondria (which drive cells), endoplasmic reticulum (synthesizes important biomolecules), Golgi apparatuses (processes and biomolecules of packages), lysosomes (decomposing dead or foreign material), chloroplasts (found in plants) and strong cytosomes). All these organelles float in the cytoplasm, GOoey, semi -transparent fluid, which functions such as "blood" cells.

In addition, eukaryote cells may have a series of surface prings used for locomotions or protection that are not in procaryoty. Examples include whip, such as those found in human sperm and cell wall found in plants. Fungus cells have a chitin cell wall, the same material used by insects for their exoskeletons. Mushrooms like mushrooms do not feel hard on contact, because the thickness of their chitin walls is much smaller than exoskeletons of insects and other arthodods.

eukaryotes have the potential for much greater complexity and diversity than prokaryotic cells. Some organelles in eukaryotic cells are in fact ancestors Prokaryot, which once had a symbiotic relationship with the eukaryot, but have been absorbed since then. Examples include mitochondria and chloroplasts. Mitochondria even have their own DNA, which over Evolution's time was slowly transferred to a better protected core.

EukaryotThey are newer among life on Earth than Prokaryota. While Prokaryots evolved 3.4 - 2.7 billion years ago, eukaryots developed between 2.1 and 1.6 billion years, although some evidence suggests a possible origin of 2.7 billion years ago. The earliest fossils of eukaryote come from 1.2 billion years ago, in the form of red algae, the type of seaweed.
