ABCs of Biology Autotroph Autotrophs are organisms that get energy from the sun. They do not need to eat other organisms. Bilateral Symmetry Bilateral symmetry is symmetry that is identical from one way. Normally straight down the center. Catalyst A substance that increases the reaction rate of a chemical reaction. DNA Is the carrier of genetic information. Embryo An unborn offspring in development. Fetus An unborn offspring about 8 weeks old after conception. Gamete A mature haploid cell Haploid Single set of unpaired chromosomes Interphase The resting phase of mitosis Joint Capsule Thin fibrous sac containing fluid with a joint. Karyotype Number and visual appearance of the chromosome in the cell nuclei of a organism. Lipid Organic compound that are fatty acids that are insoluble in water. Metaphase Second stage of cell division between prophase and anaphase. Natural Selection Process where organisms after adapted to their environment. Osmosis The tendency of a fluid, usually water, to pass through a semipermeable membrane into a solution where the solvent concentration the tendency of a fluid, usually water, to pass through a semipermeable membrane into a solution where the solvent concentration is higher, thus equalizing the concentrations of materials on either side of the membrane.is higher, thus equalizing the concentrations of materials on either side of the membrane. Pathogen Bacteria, virus, or anything that causes disease. Quaternary period Period of geology, involved the ice age and mammoths and other ice age creatures like sabretooths and sloths. Radial Symmetry Symmetry around a central axis. Seed Cone A seed that produces offspring of a plant. Trophic Level Level of hierarchy that has the higher food chain animal at the top and the autotrophs at the bottom. Uterus Women’s organ where a offspring is developed. Vacuole Space within the cytoplasm of a cell. Water Tasteless, odorless liquid that is the basic form of liquid in an organism. Xylem Vascular tissue that plants use to bring nutrients and water up. Yolk Sac Sac containing yolk attached to the embryo. Zygote Diploid cell resulting in fusion from 2 haploid gametes: sperm and egg.
