Document Summary

Eukaryotes: basic structure, plasma membrane, glycocalyx (components external to the plasma membrane, cytoplasm (semifluid, cytoskeleton - microfilaments and microtubules that suspend organelles, give shape, and allow motion, presence of characteristic membrane enclosed subcellular organelles. Plasma membrane: a lipid/protein/carbohydrate complex, providing a barrier and containing transport and signaling systems. Nucleus: double membrane surrounding the chromosomes and the nucleolus, pores allow specific communication with the cytoplasm. The nucleolus is a site for synthesis of. Mitochondria: surrounded by a double membrane with a series of folds called cristae, functions in energy production through metabolism, contains its own dna, and is believed to have originated as a captured bacterium. Chloroplasts (plastids: surrounded by a double membrane, containing stacked thylakoid membranes, responsible for photosynthesis, the trapping of light energy for the synthesis of sugars, contains dna, and like mitochondria is believed to have originated as a captured bacterium.
