Eukaryotic Cells

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

Eukaryotic Cell

• Definition
• A cell that contains a NUCLEUS

2 Types of Eukaryotic Cells

1. Animal Cell
2. Plant Cell

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
