fungi and some protists. These rigid structures provide mechanical support, maintain cell shape and protect against environmental stress. 6 Of all the eukaryotic organelles, the nucleus is the most ...

Their cell structure is simpler than the cells of animals, plants and fungi. Size Most are 5 μm ... plasmids are found in a few simple eukaryotic organisms. DNA is a single molecule, found ...

However, most fungi use a different form of cell division ... direct implications for our general understanding of how eukaryotic cell division mechanisms evolve and diversify in the context ...

The last eukaryotic ancestor (LECA) shared by all living eukaryotes today was already a complex cell by the time eukaryotes began to radiate. Over hundreds of millions of years, LECA gave rise to the ...

These experiments show that Asgard tubulins form very similar microtubules, albeit smaller than those in their eukaryotic relatives. However, only a few Lokiarchaeum cells form these microtubules.

Mitochondria occur in various forms across various eukaryotic groups ... These mitochondria are called hydrogenosomes and allow the cell to gain about 4 mol of ATP per mole of glucose.

A eukaryote is any cell or organism that possesses a clearly defined nucleus. Eukaryotic cells form the foundation of complex, multicellular life, including apple trees, mushrooms, fish and humans.
