What are eukaryotes?
Eukaryotes are unicellular or multi-cellular living organisms which have membrane-bound organelles and a nucleus enclosed by a double-layered membrane. Eukaryotes, unlike prokaryotes, have chloroplasts and/or mitochondria which are unique energy-producing organelles.
How are mitochondria similar to prokaryotes? What is the implication of this?
They are similar in size/shape, they both contain DNA, synthesize their own proteins and reproduce by binary fission.
These compelling similarities support the endosymbiotic hypothesis which states that eukaryotic cells developed a symbiotic relationship with bacteria that have evolved into present-day mitochondria.
What are four major classifications of eukaryotes?
Protists, plants, fungi and animals. Of these, only plants and fungi contain a cell wall.
How do eukaryotes reproduce?
Through meiosis, which requires two haploid cells to fuse to create a complete genome.
What makes animal eukaryotic cells unique?
Animal cells lack cell walls.
What is unique about eukaryotic ribosomes?
Eukarotic ribosomes have 
and 
subunits which may be bound to the endoplasmic reticulum or maybe free floating in the cytosol.
What metabolic pathways do eukaryotes employ?
Depending on the availability of O
, eukaryotes can use either anaerobic (glycolysis or fermentation) or aerobic (cellular respiration) metabolic pathways.
