Title: Eukaryotic Cells


1
Eukaryotic Cells
2
Robert Hook
  • Contribution to Science
  • Came up with the word cells

3
Anton van Leeuwenhoek
  • Contribution to Science
  • Discovered microorganisms in
  • pond water. He called them
  • animalcules.

4
Cell Theory
  • All living things are composed of cells
  • Cells are the basic units of structure and
    function in living things
  • New cells are produced from existing cells

5
Eukaryotic Cell
6
Eukaryotic Cell
  • Definition
  • A cell that contains a NUCLEUS

7
2 Types of Eukaryotic Cells
  1. Animal Cell
  2. Plant Cell

8
Parts of the Eukaryote
9
Cell Membrane
  • Encloses contents of entire cell

Cell Membrane
10
Cytoplasm
Gel like region that holds the organelles and
nucleus in place
11
Organelles Little Organs
  • Specialized structures within a cell

12
Organelles within an Animal Eukaryotic Cell
13
Nucleus
  • Stores the cell's DNA
  • Coordinates the cell's activities (growth,
    metabolism, protein synthesis, cell division)

14
Endoplasmic Reticulum
  • Transports materials

ER
15
Ribosomes
  • Where proteins are made
  • Look like small
  • specks throughout
  • the cytoplasm or ER

16
Golgi Apparatus
  • Receives, modifies, and ships out, proteins from
    the ER, within or outside the cell

17
Mitochondria
  • Converts chemical energy stored in food into
    usable energy for the cell

18
Lysosome
  • Break down the
  • cells food, waste,
  • and damaged
  • organelles.

19
Vacuoles
  • Stores materials such as water, salts, proteins,
    and carbohydrates until the cell needs them
