Document Summary
All living things are made of one or more cells biological molecules are all conserved. Prokaryotes vs eukaryotes prokaryotes have no nucleus eukaryotes have a nucleus, are generally bigger, and contain organelles. Eukaryotic cells contain a nucleus with membrane-bound organelles with speci c functions nucleus: contains chromatin (dna and protein) Cellular organization displays a structural hierarchy starts at the monomeric unit (nucleotide) cells to tissue to organ to organism. Biological molecules are made of a small number of possible elements. Common elements in biological molecules: h, c, n, o, na, p, s, cl, k, ca. Four major elements make up >90% of living matter: c, h, o, n they form very stable covalent bonds they can also form multiple bonds (h can form one, c can form four, etc) P and s are often found in biological energy molecules .
