Document Summary

Biology of vision - day 2 - 9/9/12. Cells - the building blocks of biological systems. Energy utilization + conversion - creation of atp, hair cells convert sound energy. Development - from the start of a life to its end; for example puberty in humans. Evolution - change over generations in biological systems. Nucleus - manages the cell and its functions. Ribosomes - works with rna and protein synthesis. Endoplasmic reticulum - involved in protein and lipid synthesis. Golgi apparatus - between er & membrane; packs protein for transport. Chromosome - dna inside nucleus; genetic material packed within dna. Vaccule - keeps structure of the cell. Picture below - chromosomes are inside of nucleus. Made primarily of phospholipids aka (also known as) membrane bilayer. Tail: hydrophobic - repels water, doesn"t mix with water. Head: hydrophilic - tends to mix with water. Cylindrical or conical - packed together gives you a cell. Lipopolysaccharides is like the cement for cell membrane.
