CHAPTER 5 STRUCTURE AND FUNCTION OF THE CELL
2
I. CELL

• THE BASIC LIVING PACKAGE OF LIFE
• AVERAGE HUMAN HAS 60,000,000,000,000 CELLS

HUMAN FAT
BLOOD
3
A. Two types of cells

• 1. Prokaryotic
• primitive cells with no nucleus or
  membranes around the
  cellparts
• - Bacteria

4

• 2. Eukaryotic
• - complex cells with a nucleus and membrane
  covered organelles.

5

• B. SOME CREATURES ARE UNICELLULAR

6
C. SOME CREATURES ARE MULTICELLULAR (MADE OF
MANY CELLS)
CHEEK CELLS
SOME HAVE TOO MANY CELLS!!

II. HISTORY

• A. ROBERT HOOKE
• - NAMED THE CELL IN 1665
• CORK
• B. VON LEEUWENHOEK - 1665
• DISCOVERED LIVING CELLS

8
LEEUWENHOEK CONTINUED

• LEEUWENHOEK DISCOVERED
• PROTOZOANS

BACTERIA
BLOOD
SPERM

C. NOW - CELL THEORY OF LIFE

• 1. ALL LIVING THINGS ARE MADE OF CELLS
• 2. ALL LIFE FUNCTIONS TAKE PLACE IN CELLS
• 3. ALL CELLS COME FROM EXISTING CELLS

III. CELL STRUCTURE BEFORE ELECTRON MICROSCOPE
ANIMAL CELLS
PLANT CELLS
11
IV. AFTER ELECTRON MICROSCOPE

• A. ANIMAL CELL

12
CLOSE UPS
13
AFTER ELECTRON MICROSCOPE

• PLANT CELL

Cilia Move the cell, move things past cell
Plasma Membrane Gatekeeper of the cell
Lysosome Suicide Sack Smooth Endoplasmic
Reticulum Makes membranes, canals Rough
Endoplasmic Reticulum Helps make,
transport protein Golgi Apparatus Makes
secretions Vacuole Stores things for cell
Mitochondrion Powerhouse, makes ATP
Centrioles Organize microtubules
Nucleus Control Center Nucleolus Makes
Ribosomes Cytoplasm Cell Jelly
Ribosomes Make Protein Chromatin Unwound
DNA plus Protein Transport Vesicle Transports
material through and out Cytoskeleton Cell
shape, movement Cell Wall Supports and
Protects plant cell Central Vacuole Stores
water, puts pressure on wall Chloroplast Food
Factory
