Introduction: Themes in the Study of Life Chapter 1 Overview: Inquiring About Life An organism?s adaptations to its environment are the result of evolution For example, the ghost plant is adapted to conserving water; this helps it to survive in the crevices of rock walls Evolution is the process of change that has transformed life on Earth ? 2011 Pearson Education, Inc. Figure 1.2 Biology is the scientific study of life Biologists ask questions such as How does a single cell develop into an organism? How does the human mind work? How do living things interact in communities? Life defies a simple, one-sentence definition Life is recognized by what living things do ? 2011 Pearson Education, Inc. Figure 1.3 Order Evolutionary adaptation Response to the environment

How does the human mind work? How do different forms of life in a forest interact? Concept 1.1: Studying the diverse forms of life reveals common themes

Similarities and Differences Found in Bacteria, Animal, and Plant Cells ? Lesson 3 Assignment Cells are the smallest unit of life. There are two categories of cells, prokaryotic and eukaryotic. Prokaryotic cells contain no nucleus or organelles. Bacteria and archaea are prokaryotic cells. Eukaryotic cells have a nucleus and separate compartments known as organelles. Cells for plants and animals are eukaryotic. Though animals, plants and bacteria are very different organisms and their cellular structures contain differences, they also have some similarities. The easiest way to show this is through the use of a Venn Diagram: http://www.uic.edu/classes/bios/bios100/lecturesf04am/lect06.htm http://www.ivyroses.com/Biology/Cells/Plant-Animal-and-Bacterial-Cells.php

Chapter 24 Early Life and the Diversification of Prokaryotes Overview: The First cells Chemical and physical processes on early Earth may have produced very simple cells through a sequence of stages: 1. Abiotic synthesis of small organic molecules 2. Joining of these small molecules into macromolecules 3. Packaging of molecules into protocells 4. Origin of self-replicating molecules Synthesis of Organic Compounds on Early Earth ? Earth formed about 4.6 billion years ago, along with the rest of the solar system ? Bombardment of Earth by rocks and ice likely vaporized water and prevented seas from forming before 4.2 to 3.9 billion years ago ? Earth?s early atmosphere likely contained water vapor and chemicals released by volcanic eruptions

18.1: Viruses and Bacteria Viruses What is a Virus? Virus: composed of nucleic acids enclosed in a protein coat and are smaller than the smallest bacterium Biologists consider viruses to be nonliving because viruses are not cells. Viruses do not carry out respiration, grow or develop. Viruses can only multiply when they are inside a living cell. Host cell: cell in which a virus replicates Almost all viruses are parasites because they destroy the cells in which they multiply. Viruses can infect the organisms of all six kingdoms. Because viruses are not alive, scientists do not use binomial nomenclature to name them.
