How Living Things Work...

4. Robert Hooke English Scientist “The Cork Cell Expert”
I’m the first in my field to locate and name cells using a microscope !!

5. 1. The cell is the basic unit of organization.
The Cell Theory
(Schleiden, Schwann, Leeuwenhoek, Virchow)
1. The cell is the basic unit of organization.
2. All organisms are composed of one or more cells.
3. All cells come from pre-existing cells

6. Vacuole storage of materials and wastes
Animal Cell
Smooth ER chemical synthesis, especially lipids and some transportation
Mitochondria powerhouse of the cell, energy (ATP) is made
Vacuole storage of materials and wastes
Golgi Apparatus packages proteins and sends them out to other parts of the cell
Lysosomes secrete enzymes for digestion
Nucleolus makes ribosomes
Nucleus control center, contains chromatin (DNA)
Centrioles aid in cell reproduction
Cytoskeleton composed of microtubles & microfilaments, framework for the cell
Cell Membrane semipermeable, regulates what moves in and out of the cell.
Cytoplasm watery environment, supports organelles
Ribosomes help make proteins
Rough ER same as smooth but has ribosomes on it

7. Plant Cells
Golgi Apparatus
Cell Wall protection, support, composed of cellulose in plants, chitin in fungi
ER (smooth & rough)
Nucleus
Nucleolus
Ribosomes
NO CENTRIOLES !!
Chloroplast contains the pigment chlorophyll to assist in photosynthesis
Lysosomes
Mitochondria
Vacuole
Cytoplasm
Cell Membrane
Cytoskeleton

8. Cilia or Flagellum ?
Hair-like structures
Whip-like tail(s)

9. Animal vs. Plant
Centrioles
No centrioles
Large vacuoles
Small vacuoles
Chloroplasts
No chloroplasts
No cell wall
Cell wall

10. Prokaryotes vs. Eukaryotes
No membrane –bound organelles
Membrane – bound organelles
No true nucleus
True nucleus
Archaebacteria and Eubacteria
Protists, Fungi, Plants, and Animals
