Document Summary
Bio 190- lecture 1 (fundamental concepts in biology) All forms of life share common properties. Properties of life include: order- highly ordered structure that typi es life. Symmetry, ex. repeated segments of the body, parts of the body. Some organisms look like blobs of nothing > microscope reveals cells lined up in order: reproduction- ability of organisms to reproduce their own kind. Bacteria simply dividing through mitosis (use ssion) -> reproduce themselves. Sexual reproduction and behaviors involved before they can reproduce > much higher diversity (genes from two different organisms: growth and development- consistent growth and development controlled by inherited dna. Once they are born or cells divide, they change. Larvae > very rst stage for a lot of organisms (look very different from the adult: energy processing- use of chemical energy to power an organism"s activities and chemical reactions.
