          Your Assignment:
 Label  the plant and animal cells
 Complete “The Cell is a Miniature Factory”
  worksheet.
 If you finish early, complete the word
  puzzle.
               Cell Theory:
 All living things are composed of cells. The
  cell is the basic living unit of organization.
 All cells arise from pre-existing cells. Cells
  do not come from non-living things.

 Allcells: are bound by a membrane
  (plasma membrane), organelles float in
  cytosol, chromosomes (DNA), and
  ribosomes.
Prokaryotic Cell vs. Eukaryotic Cell
 The nucleus has no         The nucleus is bound
  membrane separating         by a membranous
  it from the rest of the     nuclear envelop.

Flagella          Chloroplasts
Lysosomes         Central Vacuole
Centrioles        Cell Walls
                     Mitochondria
   The “power plant” of the cell
   Provide the cell with energy in a process called
    cell respiration.
   sugar + oxygen = carbon dioxide + water + energy
   The energy is from the breakdown of the sugar
    molecules bonds.
   2 membranes; inner membrane has fingerlike
    projections that increase the surface area.
   Contains its own DNA
   36% of energy is converted into adenosine
    triphosphate (ATP), a chemical storage
    molecule.
   64% is converted to thermal energy.
               Chloroplasts
 organelles of photosynthesis
 The inner membrane contains the green
  pigment molecule, chlorophyll – coverts light
  energy to chemical energy.
 Chloroplast have their own DNA.
 In photosynthesis, chloroplasts use energy from
  the sun to convert carbon dioxide and water into
  food molecules like sugars and other
  carbohydrates.
