Document Summary
Chapter 1 introduction: what makes something a plant, the combination of how it reproduces, its structure, and how it gets its nutrition and energy. They make food/energy through the process of photosynthesis. Plants don"t move; they have very rigid cell walls. Plants have flowers/seeds/fruits, spores (ferns/mosses), or cones (conifers) as their mode of reproduction: organisms are named according to the binomial system genus and species, ex. Homo sapiens: organisms are classified on the basis of their evolutionary/genetic relatedness. The kingdom is the highest (most all-inclusive) grouping of life: kingdom, phylum, class, order, family, genus, species. The five kingdoms of life are bacteria, animals, fungi, protists, and plants: bacteria were the first organisms to evolve. Life first appeared on earth 3. 5 billion years ago. Photosynthesis evolved 3 billion years ago: multi-cellular organisms evolved 1. 5 billion years ago, green plants evolved 1 billion years ago.
