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

A Tour of the Cell Chapter 6 Overview: The Fundamental Units of Life All organisms are made of cells The cell is the simplest collection of matter that can be alive Cell structure is correlated to cellular function All cells are related by their descent from earlier cells ? 2011 Pearson Education, Inc. Figure 6.1 Concept 6.1: Biologists use microscopes and the tools of biochemistry to study cells Though usually too small to be seen by the unaided eye, cells can be complex ? 2011 Pearson Education, Inc. Microscopy Scientists use microscopes to visualize cells too small to see with the naked eye In a light microscope (LM), visible light is passed through a specimen and then through glass lenses Lenses refract (bend) the light, so that the image is magnified

Meredith Robbins Ms. Sobota The Environmental Effects on Mitosis Research Question: How much of an effect does the IAA have on the rate of cell division in onion roots? Null Hypothesis: The IAA will not have a significant impact on the rate of cell division. Alternative Hypothesis 1: If the IAA is added to the water/ soil then it will have a higher rate on cell division. Alternative Hypothesis 2: If the IAA is added to the water/ soil then it will have a lower rate on cell division. IV: IAA DV: The rate of Cell Division Summary:

AP Biology Reading Guide Chapter 6: A Tour of the Cell Fred and Theresa Holtzclaw Copyright ? 2010 Pearson Education, Inc. - 1 - Name_______________________Period___________ Chapter 6: A Tour of the Cell Concept 6.1 To study cells, biologists use microscopes and the tools of biochemistry 1. The study of cells has been limited by their small size, and so they were not seen and described until 1665, when Robert Hooke first looked at dead cells from an oak tree. His contemporary, Anton van Leeuwenhoek, crafted lenses; and with the improvements in optical aids, a new world was opened. Magnification and resolving power limit what can be seen. Explain the difference.

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. Attribution-Noncommercial 3.0 United States, more free study guides at www.Biology101.org, copyright Anthony D'Onofrio a quick overview The basic diagram of the cell shown above represents most eukaryotic cells (humans, plants, fungi). One main distinction is that plants have a cell wall outside the cell membrane that animal cells lack.
