In cell biology, an organelle is a discrete structure of a cell having specialized functions. There are many types of organelles, particularly in the eukaryotic cells of higher organisms. An organelle is to the cell what an organ is to the body (hence the name organelle, the suffix -elle being a diminutive). Organelles were historically identified through the use of microscopy, and were also identified through the use of cell fractionation.
A few large organelles probably originated from endosymbiont bacteria:
- mitochondria (in almost all eukaryotes)
- plastids (in plants and algae)

Still have to do all my home work study all the organelles for bio and memorise all the countries in the middle east... Sounds fun don't it

Dude. What the fuck is a balancer chromosome? This is why I work in bacteria. One chromosome, no organelles. Simplicity.

@lfc_lxy what's in the shithole (between membrane and cell wall) i think it's water? organelles? idk. won't be tested. it's just a shithole.
