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

The Cell The cell is one of the most important concepts in biology since every living organism is made of cells. Bacteria are single celled while you are made up of trillions of cells. As different as we are from bacteria, our cells share some important similarities. All cells have a cell membrane that separates them from the outside environment and all cells have ribosomes where proteins are made.

One main distinction is that plants have a cell wall outside the cell membrane that animal cells lack.

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

Name_________________________________Date_______________________Pd._____ Cell Review Worksheet Complete the following table by writing the name of the cell part or organelle in the right hand column that matches the structure/function in the left hand column. A cell part may be used more than once. Structure/Function Cell part 1. Stores material within the cell 2. Digests excess or worn-out cell parts, food particles and invading viruses or bacteria 3. Site of protein synthesis 4. Jelly-like substance in the cell 5. Organelle that manages or controls all the cell functions in a eukaryotic cell 6. Contains chlorophyll, a green pigment that traps energy from sunlight and gives plants their green color

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

Mechanisms of Bacterial Genetic Recombination Genetic Transfer Genetic transfer is the mechanism by which DNA is transferred from a donar to a recipient. In bacteria genetic transfer can happen three ways: Transformation Transduction Conjugation A recombination event must occur after transfer in order that the change in the genome be heritable (passed on to the next generation). Transformation After death or cell lyses, some bacteria release their DNA into the environment. Other bacteria, generally of the same species, can come into contact with these fragments, take them up and incorporate them into their DNA by recombination. This method of transfer is the process of transformation. Any DNA that is not integrated into the chromosome will be degraded.

Chapter 18: Genetics of Viruses and Bacteria Concept 18.2 is not required knowledge for the AP Exam and has been intentionally omitted. Overview: Microbial Model Systems viruses called bacteriophages can infect and set in motion a genetic takeover of bacteria E. coli and its viruses are called model systems because of their frequent use by researches in studies that reveal broad biological principles beyond their value as model systems, viruses and bacteria have unique genetic mechanisms that are interesting in their own right bacteria are prokaryotes with cells much smaller and more simply organized than those of eukaryotes viruses are smaller and simpler still Concept 18.1: A virus has a genome but can reproduce only within a host cell
