1. Learning targets for the Cell…
I CAN
Day 1:
Explain the cell theory
List the characteristics of prokaryotic and eukaryotic cells
Days 2 & 3:
Identify & define the function of the organelles
Create a Venn diagram to illustrate the similarities and differences between an animal & plant cell
Compare organelles in unicellular organisms to the body systems in multicellular organism
Use an analogy to explain how the organelles function

2. Boy! What a little cell can do!
The Cell and it’s Parts!
Boy! What a little cell can do!

3. smallest unit of life that is capable of performing life functions.
The Cell is the….
smallest unit of life that is capable of performing life functions.

4. Organization Cells  Tissues  Organs  Organ systems  Organism
Muscle cell Smooth muscle Stomach Digestive YOU
Tissue organ System
SMP - LE 2013 notes

5. History of the cell?
Compound light microscope
SMP - LE 2013 notes

6. The 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
EXCEPTION to the cell theory:
viruses
SMP - LE 2013 notes

7. Cells have 3 Main Jobs ATP
1. Making energy to fuel daily life & growth, the cell must…
take in nutrients, oxygen (O2)
make ATP (mitochondria)
remove waste (carbon dioxide)
ATP
SMP - LE 2013 notes

8. Our organelles do all these jobs!
2. Make proteins (ribosomes)
proteins do all the work in a
cell, so we need lots of them
3. Make more cells (during mitosis)
for growth
to replace damaged or diseased cells
SMP - LE 2013 notes

9. Cells come in all shapes and sizes…
How Big is a cell... ?

10. Examples of Cells Amoeba Proteus Plant Stem Bacteria Red Blood Cell
Nerve Cell
Skin cell

11. TYPES OF CELLS Prokaryotes Eukaryotes Have cell membrane
Have cytoplasm
DNA is free floating in cytoplasm
NO NUCLEUS
Bacteria!
Eukaryotes
Have cell membrane
Have cytoplasm
DNA is contained
IN NUCLEUS
Have organelles
Specialized structures with specific functions
SMP - LE 2013 notes

12. CELL STRUCTURE
Plant and animal cells differ slightly in the organelles they contain

13. Organelles - “little organs of the cell”
The following organelles are in BOTH plant and animal cells (Eukaryotes )
VIDEO:

14. Cell Membrane: The Video Clip

15. Site of chemical reactions Contained by cell membrane OVER 80% water
Functions:
Semi–permeable; Regulates what goes in and out of cell
Receives signals from other cells (in multicellular orgs)
2. Cytoplasm:
Function:
Site of chemical reactions
Contained by cell membrane
OVER 80% water
SMP - LE 2013 notes

16. Nucleus

17. 3. Nucleus LABEL Function: ME nucleolus 4. Nucleolus:
Contains DNA (chromatin)
“Control center” of cell
Surrounded by nuclear membrane
4. Nucleolus:
Center of nucleus
Site of ribosome synthesis
LABEL ME
nucleolus
Nuclear membrane
SMP - LE 2013 notes

18. Ribosomes: The Video Clip

19. 5. Ribosomes (the protein makers)
Function:
Site of protein synthesis
“Little dots”
6. Endoplasmic Reticulum (ER)
Assembly of cell parts and transport
“Smooth” has no ribosomes
“Rough” has ribosomes on surface
7. Golgi Apparatus (The “Post Office” of the cell)
Proteins are packaged and shipped here
SMP - LE 2013 notes

20. Site of cellular respiration Releasing energy (ATP) from food
8. Mitochondria
Function:
Site of cellular respiration
Releasing energy (ATP) from food
“Powerhouse” of the cell
9. Vacuole
Empty space used for storage
Much LARGER in plant cells…WHY?
Need to store water and starch
SMP - LE 2013 notes

21. Vacuoles in One celled Organisms
Add to bottom of note sheet
Vacuoles in One celled Organisms
Crucial in maintaining homeostasis
Food Vacuole- stores and digests food
Contractile vacuole- pumps excess water from cells

22. Ode to a Plant Cell: Cell Wall and Vacuole

23. ONLY IN PLANTS Cell Wall Non- living structure (cellulose)
Function:
Provides Support and Protection so that plants can grow tall.
Surrounds cell membrane
Non- living structure (cellulose)
They allow water, oxygen, and carbon dioxide to pass through it.

24. Chloroplast

25. Chloroplast Chloroplast Function: Site of photosynthesis
Uses sun’s energy and water to make food (glucose) giving off oxygen as a waste
Chloroplast contain the pigment CHLOROPHYLL which makes most plants appear GREEN!!
Chloroplast
SMP - LE 2013 notes

26. ONLY IN ANIMAL CELLS CENTRIOLES Function: division of cells
cylindrical structure in the cytoplasm
located near the nucleus
Lysosomes
Contain enzymes that break down things

27. Animal Cell Nucleus Cell membrane Rough ER Smooth ER cytoplasm
Golgi body
mitochondria
lysosome

28. Plant Cell Cell wall Cell Membrane Chloroplast vacuole Mitochondria
Nucleus
Golgi Body

29. Let’s compare unicellular to multicellular organisms!
Nucleus
Cell Membrane
Lysosome
Multicellular
Nervous system
Skin; Respiratory
Digestive system

30. Let’s compare Animal and Plant cells
