Biol & 213 is the third course of a year-long series of biology courses for Biology majors. The first third of the course surveys prokaryotes, protists, fungi, and plants, focusing on diversity, evolution, and life cycles from an evolutionary perspective. We will then describe plant anatomy, physiology, growth, responses to the environment, and reproduction, emphasizing flowering plants. We will finish with ecology, focusing on population, and community ecology and expanding outward to ecosystems and the introduction of biodiversity and conservation.

Paul Andersen describes mechanisms that increase the genetic variation within a population. He begins by discussing how horizontal transfer can move genetic material between bacteria. Transformation, transduction, and conjugation in bacteria are all included. He also explains how crossing over, random assortment, and random fertilization can maintain genetic variation in eukaryotes.

Paul Andersen explains how organisms regulate timing and control. Phototropism and Photoperiodism allow plants to respond to light throughout the day and year. Circadian rhythms are used in all organisms (including animals) as an internal clock. Bacteria use quorum sensing to communicate the number of bacteria present.
