Document Summary

Only plant cells have cell walls and chloroplasts. The cell theory states that all organisms are made up of cells and all cells come from pre-existing cells. Deoxyribonucleic acid (dna) contains genes (transmitted to offspring) with information within cells: replicated or copied when cell divides, chromosomes created are identical to parent cells. Theory of evolution: characteristics of species change through time. Evolution occurs when individuals with certain heritable traits (change in genetic structure over time) produce more offspring than individuals lacking these traits. Advantageous traits are passed on through reproduction or natural selection. Helps construct evolutionary pathways and enables interpretation of origins and history. Binomial nomenclature: unique two-part scientific name consisting of the genus and species. Taxonomy: branch of biology that deals with classifying and naming organisms, taxa (taxonomic unit at any level) should share a common ancestor, evolutionary sense evolutionary relationships and relatedness. Organisms are composed of matter anything that has mass and takes up space.
