1. Do Now:
My planet diary: page 12 of the textbook. Read and answer the two questions into your science notebooks

2. How do stains make it easier to study the parts in the cell?
Stains help scientists see structures inside of cells that would otherwise be invisible

3. Cells and Heredity Chapter 1, Lesson 2
Looking inside cells
Cells and Heredity Chapter 1, Lesson 2

4. How do parts of a cell work?
Each kind of cell structure has a different function within a cell

5. Cell Types Cells can be divided into two groups
1. Eukaryotic Cells – Cells with membrane bound structures. Have a nucleus
2. Prokaryotic Cells – no membrane bound structures inside the cell. No True Nucleus
- Ex: Bacteria

7. Into what two groups can cells be separated?
Prokaryotic and Eukaryotic Cells

8. Cell Wall Surrounds cell and gives it a rigid, boxlike shape
Found in plants, fungi, algae, most bacteria
Mostly made up of cellulose (carbohydrate)
Allows water and dissolved materials to pass through

9. Cell Membrane Found in Both
Controls which substances move into and out of a cell
The cell membrane is semipermeable
“Screen window” for the cell

10. Color in the cell membrane
On Page 13 color in the cell membrane

11. Nucleus Directs all cell activity Largest cell structure
Found in both cells
Contains Chromatin: long threadlike hereditary material made of DNA.
Contains Nucleolus- small round structure in nucleus
Separated from cytoplasm by a membrane
“Brain of the CELL”

12. organelles
Organelles- tiny cell structures that carry out specific functions within a cell

13. Ribosomes Produce proteins needed by cell Found in both cells
Some flow freely in cytoplasm some are attached to the ER
“Ribs provide us proteins”

14. Cytoplasm Fill most of cell; moves organelles within cell
helps hold organelles in place
Found in both
“Gel in the Cell”

15. Mitochondria Mitochondria – Rod like structures
Convert energy stored in food to energy used by cell
Found in both cells
Power House of the cell
“Mighty Mitochondria Superhero of the cell”

16. Endoplasmic Reticulum
Looks like maze of passageways
helps make proteins and other substances.
Found in both cells
Rough – ribosomes attached
Smooth – no ribosomes attached
ER – “ambulance of the cell.” “Mailman”

17. Color page 15
Color in the various cell parts on page 15

18. Golgi Apparatus (Bodies)
Stacked, flatten membranes
Packages and distributes materials from ER
Found in both cells
“Post office of the cell”

19. Vacuole Stores water, food, waste and other cellular materials
Plants cells have one or more large vacuoles (for storing water).
Animals cells: some have vacuoles but don’t always have them

20. Chloroplasts In plant cells
Contain a green pigment (color) called chlorophyll which gives plants their green color.
Chloroplasts makes food for cell using energy from sunlight

22. Lysosomes Saclike organelle
break down food particles and worn out cell parts
Found only in animal cells
Lysosomes membrane prevents digestive chemicals inside from leaking into the cytoplasm
“Lysol” or “Recycling Center”

23. Endoplasmic Reticulum Nucleus
Which cell part controls what goes in and out of the cell?
Which organelle stores water, food, and waste?
Lysosome
Mitochondrion
Vacuole
Cell Membrane
Endoplasmic Reticulum
Nucleus

24. Lysosome Cell Membrane Ribosome Nucleus Vacuole Chloroplast
What is one cell part a plant cell has that an animal cell does not?
Where are proteins made?
Lysosome
Ribosome
Vacuole
Cell Membrane
Nucleus
Chloroplast

26. Cell City

27. Compare a cell to a restaurant
Identify and explain how a cell can be compared to a restaurant. Use the structure of the building as well as the workers to make comparisons

28. Cell vs. Restaurant Nucleus - Kitchen Cell membrane – Doors
Cell Wall – Restaurant Wall
Lysosome – Dumpster / Trash / Bathrooms
Mitochondria – Electrical Outlets
Vacuoles – Fridge
Golgi Bodies – Chef
Ribosomes – Table Buser
ER – Waiters
Now for homework, you will come up with your own Cell Analogy on Google Classroom!

29. How do cells work together in an organism?
Part 2
How do cells work together in an organism?

30. Think about it…
During the Microscope Stations Lab, you looked at 3 different cells: cork onion animal
Based on your observations, do you think all cells look the same?

31. Comparing Cells Nerve Cell - can be a meter long
Human Egg Cell – no bigger than the dot on this i

32. Comparing Cells The shape of a cell may tell you about its’ function
Bacterium – smaller than all the other cells
Human Blood Cell – 1/10 the size of the human egg
The shape of a cell may tell you about its’ function

33. In your textbook…
Look at page 20, Figure 6 Match the Function with the Specialized Cell

34. Multicellular
Consisting of many cells
Example: plants and animals

35. Unicellular Made of a single cell
Example: bacteria, protists (amoeba, plankton)

36. Specialized Cells
Cell – basic unit of structure and function in an organism
In multicellular organisms, cells are specialized and perform specific functions that benefit the entire organism

37. Cells Working Together
Tissue – a group of similar cells that perform a specific function
Organ – a body structure that is composed to different kinds of tissues that work together
Organ system- a group of organs that work together to perform a major function
In multicellular organisms, cells are organized into tissues, organs, and organ systems

39. What types of tissues make up your heart?
Cardiac muscle tissue, nerve tissue, and blood tissue

40. In your textbook…
Look at page 21, Figure 7 Let’s compare the Organization of Your Body to the Organization of Your School
