Document Summary

Sunlight as energy source: electromagnetic spectrum- range of all possible frequencies of radiation, photons- discrete packets of kinetic energy. Same- plasma membrane: semifluid substance called cytosol, chromosomes (gene carriers, ribosomes (protein makers) Prokaryotic: only organisms of the domains bacteria and. Not a taxon: "prokaryotes: no nucleus, no membrane bound organelles, dna in an unbonded region called the nucleoid. Ribosomes: protien factories: ribosomes are particles made up of ribosomal rna and protien, ribosomes carry out protien synthesis in two locations. On the outside of the endoplasmic reticulum or the nuclear envelope (bound ribosomes: decode mrna. Endomembrane system regulates protien traffic and performs metabolic functions in the cell: components of the endomembrane system. Plasma membrane: the components are either continuous or connected via transfer vesicles. The endoplasmic reticulum: biosynthetic factory: the er accounts for more than half of the total membrane in many eukaryotic cells, the er membrane is continuous with the nuclear envelope, there are two distinct region of er.
