1. Cell Research Quest!

2. What is a Cell? A cell is the smallest unit of life.
Your body is made up of trillions of cells with each one working hard to produce proteins.
These proteins are used as building blocks for many different things. For example, your hair and nails are made up of a special protein made by cells.
However, in order to carry out this important task, cells are made of tiny structures that work together. These tiny structures are called organelles.

3. This cell part is just like…
CELL MEMBRANE
Organelle
Plant, Animal, or Both?
Function
This cell part is just like…
Cell Membrane
Both
Surrounds the outside of the cell.
Controls what substances can
enter and exit the cell
Gatekeeper

4. This cell part is just like…
CELL WALL
Organelle
Plant, Animal, or Both?
Function
This cell part is just like…
Cell Wall
Plant
Surrounds the cell membrane ;It
is a tough and rigid covering
made of cellulose
Gives a plant shape, support, and
protection
Tough,
Outer Fence

5. This cell part is just like…
CYTOPLASM (Cytosol)
Organelle
Plant, Animal, or Both?
Function
This cell part is just like…
Cytoplasm (cytosol)
Both
Jelly-like fluid in cell
Holds all other organelles in place
Jell-O

6. This cell part is just like…
NUCLEUS
Organelle
Plant, Animal, or Both?
Function
This cell part is just like…
Nucleus
Both
The nucleus is protected by a nuclear membrane. This membrane protects the nucleus allowing certain materials to enter and exit through pores.
Nucleus controls and directs all of the cell’s activities
The nucleus also protects a cell’s genetic material called chromatin. Another word for chromatin is DNA. DNA contains all the instructions for how a cell should grow and what proteins it should make.
Brain

7. This cell part is just like…
NUCLEOLUS
Organelle
Plant, Animal, or Both?
Function
This cell part is just like…
Nucleolus
Both
Dark region inside the nucleus
The site where ribosomes are made
Center of tootsie roll pop

8. This cell part is just like…
RIBOSOMES
Organelle
Plant, Animal, or Both?
Function
This cell part is just like…
Ribosome
Both
Small, grain-like bodies floating in
the cytoplasm or attached to the
Endoplasmic Reticulum
Responsible for making proteins
Factory
Worker

9. Endoplasmic Reticulum
Organelle
Plant, Animal, or Both?
Function
This cell part is just like… ER
Both
A maze of tube-like membranes.
Rough ER: studded with ribosomes
Smooth ER: does not have ribosomes
Rough ER: Acts as a passageway for protein material sending it to the Golgi body
Smooth ER: Acts as a passageway for non-protein material (fats and carbohydrates)
Subway Tunnel

10. This cell part is just like…
GOLGI BODY
Organelle
Plant, Animal, or Both?
Function
This cell part is just like…
Golgi body
Both
Flattened stacks of membrane (looks
like pita bread)
Works to package, tag, and ship a
protein to its destination inside or
outside of the cell.
Mailroom

11. This cell part is just like…
VESICLE
Organelle
Plant, Animal, or Both?
Function
This cell part is just like…
Vesicle
Both
Small membrane sacs
Transports proteins from one part of the cell to another

13. This cell part is just like…
LYSOSOME
Organelle
Plant, Animal, or Both?
Function
This cell part is just like…
Lysosomes
Both
Small membrane sacs
Contains special chemicals to digest food, old cell parts, or waste
Garbage Disposal

14. This cell part is just like…
MITOCHONDRIA
Organelle
Plant, Animal, or Both?
Function
This cell part is just like…
Mitochondria
Both
A jelly-bean structure with an outer membrane and inner membrane which is folded.
Produces usable energy for the cell by breaking down sugar called glucose (powerhouse of the cell)
