1. Happy Monday! 5-1-17 Come in Quietly
Pick up a Cell Rubric and Cell parts Handout
Have your binder open to section 10.4
Begin writing in your planner for the week.

2. Looking inside the cells 10.4

3. How Do the Parts of a Cell Work?
Each kind of cell structure has a different and specialized function within a cell.

4. Cell Wall Protects and supports the cell It’s like a city wall!
Rigid layer Surrounding cell Only in plant cells (and some organisms like mushrooms)
Protects and supports the cell
It’s like a city wall!

5. Cell membrane
It’s like the border
of a city!
Function- Controls which substances pass into and out of a cell.
Structure- surrounds the cell and separates it from the outside

6. What cells have a cell wall?
Plant B. Animal C. Both
Answer:
Only PLANT CELLS DO
What Cells have a cell membrane?
Plant B. Animal C. Both
C. BOTH

7. Organelles
Parts of the cell that each carry out their own specific function
The Nucleus is the largest of these…

8. Nucleus •Structure: Large, oval shape Centrally located in cell
• Function: Controls cell activities
Contains genetic
information (DNA)
NUCLEAR MEMBRANE
SURROUNDS THE NUCLEUS, IT LETS MOLECULES PASS THROUGH ITS PORES.

9. Chromatin
Thin strands of DNA and proteins that fill the nucleus, contains information for directing a cell’s functions.

10. NUCLEOLUS
Small round structure in the nucleus; Makes ribosomes

11. Cytoplasm
• Structure: Clear, thick, jelly-like material, Located beneath cell membrane
•Function: Supports and protects cell organelles and carries them around the cell

12. Ribosomes
• Structures: The small round structures in the cell, smallest organelles, can be attached to the Endoplasmic Membrane
or floating free in the
Cytoplasm.
• Function:
Produces proteins

13. Mitochondria • Structure: Looks like a jellybean
• Function: Breaks down sugar molecules to release usable energy
• Has inner foldings that increase the internal surface area

14. Endoplasmic Reticulum
• Structure: Network of tubes
• Function: Transports materials throughout the cell
• Two types
-Smooth (no ribosomes)
–Rough (covered with
ribosomes)
E R helps the attached
ribosomes make
protein.

15. It surrounds the nucleus

16. Golgi Apparatus It’s like a city’s Post Office or UPS center!
• Structure: Looks like a flattened stack of membranes (or pancakes!)
• Function: Processes and packages molecules, like lipids
and proteins, that were
made by the cell
Fun Fact:
Named for the person
Who discovered it in
Cells in 1898 :
Camillo Golgi
It’s like a city’s
Post Office or UPS
center!

17. Vacuole Structure: – In plant cells: very few and very large
Animal Vacuole
Plant Vacuole
Structure:
– In plant cells: very
few and very large
– In animal cells:
many little ones
Function:
• Fluid-filled sacs
• Store food, water and
waste
It’s like a city’s
warehouses, water
towers and
garbage dumps!

18. Chloroplasts Found in plant cells only • Structure: Oval-shaped
• Green in color due to
Chlorophyll
•Function: Uses energy from the sun to make food for the plant
It’s like the solar
panels on a city’s
buildings!

19. LYSOSOMES • Found in animal cells only.
• Structure: Small and round in shape
• Function:Breaks down larger food molecules into smaller ones.
Why do you think plants do not need lysosomes?
They make food (sugar)
that is readily used by
the mitochondia for fuel
• Lysosomes also digest
old cell parts, so It’s like a city’s Recycling
Center!

22. What does the nuclear envelope do? It surrounds the nucleus.
Review Questions
What does the nuclear envelope do?
It surrounds the nucleus.
2. What do ribosomes do?
Make proteins
3. How do you think making rea-world comparisons with cells helps you understand cell structure and function?
Real world comparisons relate to what I know and don’t know.
Summarize how the functions of organelles in animal cells and plant cells are the same and different.
In both kinds of cells most structures function the same way. In plants, chloroplast make food, and a cell wall protects and supports the cell. Animal cells have lysosomes that break down food particles and worn-out cell parts.
A solar panel collects sunlight and converts it to heat or electrical energy. How is a solar panel similar to chloroplast? Like chloroplast, a solar panel changes sunlight into another form of usable energy.
6. What are cells made of?
A cell membrane, a nucleus, cytoplasm and other organelles.
