CELL WALL

13. Cells and their Organelles
DNA = deoxyribonucleic acid
7. Where is DNA found inside the cell?
8. What cell process is controlled by the nucleus?
9. DNA coils tightly during division and assembles into visible __________________.
Nucleus
Many functions – specifically protein synthesis.
Chromosomes

14. Cells and their Organelles
10. Where are organelles located?
11. Where are proteins made in the cell?
12. Do all cells need ribosomes?
13. The process of making proteins is called __________________________________.
Inside the cell – all through the cytoplasm
Ribosomes
All cells need protein so all cells need the protein maker - RIBOSOMES
Protein synthesis

15. Compound Microscope 1. Eye Piece – lens closest to the eye.
2. Body Tube – gives distance between eyepiece and objective.
3. Nose Piece – holds the objectives.
4. Arm – holds the tube and lenses.
5. Objective lenses –
lens closest to the slide.
6. Stage – platform for the slides.
7. Stage clips –
Holds the slide in place.
8. Coarse Adjustment knob –
Moves stage up/down (to focus).
9. Diaphragm / IRIS –
Controls the amount of light.
10. Fine Adjustment knob –
Moves stage up/down slightly
11. Light –
Shines light through the slide, lens, tube.
12. Base – Holds up the entire microscope.

16. 1. Add color
2. Read through events
3. Cut out and align
4. Glue in place (more than one paper is okay.

20. Cells and their Organelles
ER = Endoplasmic reticulum
14. How does rough ER differ from smooth ER?
15. Rough ER is connected to the _______________________ and to the ____________________ ER.
Rough has ribosomes (making it rough or bumpy). Smooth does not have ribosomes.
Outer nuclear membrane
smooth

21. Cells and their Organelles
Endoplasmic reticulum
16. Proteins made by rough ER travel to the Golgi in sacks called _____________. Golgi ____________ and ___________ proteins for export out of the cell.
Give three jobs of the ER. A. B. C.
Vesicles
modifies
packages
Makes proteins and lipids
Controls calcium levels in muscles
Detoxifies poisons, alcohol, drugs.

22. Cells and their organelles
18. What process takes place inside chloroplasts? 19. What is the energy for this process? 20. What pigment traps the energy?
Photosynthesis – food energy from light energy
The light energy is typically the sun.
Chlorophyll (green) helps to change light energy into food energy.

23. Cells and their organelles
21. Chloroplasts are found in what type of cell(s)? 22. Both chloroplasts and mitochondria are like in that they both have _________________ membranes and their own _______. 23. Food, water, and wastes are stored inside ______________.
PLANT only…and a few protists
double
DNA
Vacuoles

24. Cells and their organelles
24. Digestion takes place inside _____________ containing _____________. The largest organelle in plants is the ____________ _____________. What organelle breaks down and recycles worn out cells?
lysosomes
Digestive enzymes
Central vacuole
Lysosomes

25. CELLS

26. Cell Membrane BOTH Plant and Animal Cells
Function: controls what substances enter and exit the cell
Analogy to City: City “Gate Keeper”

27. Cell Wall PLANT CELLS ONLY
Function: surrounds plants to protect and support the cell
Analogy to City: City Border

28. Nucleus BOTH Plant and Animal Cells
Function: directs all the cells activities (brain of cell)
Analogy to City: City Hall

29. Nucleolus BOTH Plant and Animal Cells
Function: makes ribosomes inside the nucleus
Analogy to City: Copy Machine Inside City Hall

30. Nuclear Membrane BOTH Plant and Animal Cells

41. 1. Choose the wrong statement from the following.
a) Mitochondria produces most of the energy for the cell.
b) Chloroplasts are “food producers.”
c) Cell wall controls the movements of materials into and out of the cell.
d) Nucleus regulates and controls all cell activities, acting as the “brain” of the cell.

42. 2. Match the cell part to the nickname.

43. School analogy Cut the doors/windows – just three sides.
Put the schoolhouse onto colorful paper and trace the box space.
Remove the schoolhouse and cut out the square place descriptions.
Determine where each square goes – and then glue!
Put schoolhouse over top and glue.
