Unit 1 - Chapters 1 - 5

Methods And Concepts in Biology

Chemical Foundations for Cells

Cell Structure and Function

 

Essential Questions:

  • What is Biology?
  • How is Biology Studied?
  • What are the essential properties of water that makes it possible to support life?
  • What are the chemicals that make up living things?
  • Why is carbon the base molecule for life?
  • What are the larger organic molecules that make up living things and how are the composed?
  • How does the form of a molecule relate to its function?
  • What is the smallest living unit?
  • How is a cell a self contained system?
  • What are the components of the cell and what are their functions?

Objectives:

CH. 1

  • List the features that distinguish living Organisms from nonliving matter.
  • Describe the general pattern of energy flow through Earth's life forms, and explain how Earth's resources are cycled.
  • Explain what is meant by the term diversity, and speculate about what caused the great diversity of life forms on Earth
  • List the steps of the scientific approach to understanding a problem.
  • Discuss the major themes that run throughout the study of biology.
  • Understand what limitations are imposed on science and scientists.

CH. 2

  • Understand how protons, electrons, and neutrons are arranged in to atoms.
  • Explain how the distribution of electrons in an atom or ion determines the number and kinds of chemical bonds that can be formed.
  • Know the various types of chemical bonds, the circumstances under which each forms, and the relative strengths of each type.
  • Understand the essential chemistry of water and some common substances dissolved in it.
  • Understand the pH scale and the definition of acids, bases, buffers, and salts.

CH. 3

  • Understand how small organic molecules can be assembled in to large macromolecules by dehydration synthesis (condensation).  Understand how large macromolecules can be broken apart in to their subunits by hydrolysis.
  • Memorize the functional groups presented and know the properties they confer when attached to other molecules.
  • Know the general structure of a mono-saccharide with six carbon atoms, glycerol, a fatty acid, an amino acid, and a nucleotide.
  • Know the macromolecules into which these essential building blocks can be assembled by dehydration synthesis.
  • Know where these carbon compounds tend to be located in cells or organelles and the activities in which they participate.

CH. 4

  • Understand the basic tenets of the cell theory.
  • Contrast general features of prokaryotic and eukaryotic cells.
  • Describe the nucleus of eukaryotes with respect to structure and function.
  • Describe the organelles associated with the cytomembrane system, and tell the general function of each.
  • Contrast the structure and function of mitochondria and chloroplasts.
  • Describe the cytoskeleton of eukaryotes and distinguish it from the cytomembrane system.

Ch. 5

  • Understand the essential structure and function of the cell membrane.
  • List several surface structures of cells and tell how they help cells survive.
  • Understand what properties govern the movement of molecules and explain different ways molecules move across the cell membrane.
