Document Summary

Biol 1001 lecture 7 structure and function of cells. Eukaryotic cells: cell is smallest unit of life, can survive on its own or has potential to do so, senses and responds to environment. Structure of cells: all cells start out life with, plasma membrane, region where dna is stored, cytoplasm, two types of cells, prokaryotic cells do not have a true nucleus, eukaryotic cells have a true nucleus. Animal cell components: plasma membrane, nucleus (is lost in red blood cells, ribosomes, endoplasmic reticulum, golgi body, vesicles, lysosomes, peroxisomes, mitochondria, cytoskeleton, centrioles. Parts of a cell pl bilayer: main component of cell membranes, gives membrane is fluid properties, phospholipid bilayer, hydrophilic heads face outward, hydrophobic tails in center. Diffusion across plasma membrane: although molecules collide randomly, net movement is away from the place with the most collisions (down a gradient, movement due to brownian motion. Tonicity: relative solute concentration of two fluids, hypertonic having more solute.
