The text describes several organelles in eukaryotic cells that seem to operate like bacterium. What relationship does this sugge
st between prokaryotes and eukaryotes? This suggests an endosymbiotic relationship between prokaryotes and eukaryotes caused eukaryotes to evolve from prokaryotes. Tell me how this evolution happened and what evidence supports this theory.
Eukaryotes are the cells that make up our bodies, plants and animals and all cellular organisms that contain their genetic material in a nucleus, have a cytoskeleton and contain organelles, such as mitochondria or cytoplasts. Eukaryotes are thought to have evolved from prokaryotes. Bacteria and archaea are classified as prokaryotes, a group of simple, single-cell organisms. Prokaryotes usually contain a single, circular deoxyribonucleic acid, DNA, molecule and lack a nucleus and intracellular organelles.
The kidney is referred to as an excretory organ because it excretes nitrogenous wastes. It is also a major homeostatic organ because it maintains the electrolyte Acid-Base, and fluid balance of the blood.
