Cell Functions

The Functions & Structures of Cell.

1. Biology 133

3. Cell Parts and Functions
Cell Membrane
Protects the cell
Lets things in and out of the cell
Location: around the cell
Nucleus
Control center
Location: inside the cell,
near the center

4. Cell Parts and Functions
Nucleolus (Nucleoli)
Makes ribosomes
Location: inside the nucleus
(dark spot)
Nuclear Membrane
Protects nucleus
Lets things in/out of nucleus (pores)
Location: around nucleus

cell

6. Cell Parts and Functions
Mitochondria
Makes energy/powerhouse
Location: in cytoplasm
Golgi Bodies/Apparatus
Packages and secretes
(gets rid of) waste
Location: in cytoplasm

7. Mitochondria

8. GOLGI APPARATUS

9. Cell Parts and Functions
Endoplasmic Reticulum (E.R.)
Transports materials and sends messages to all parts of the
cell
Two types: smooth and rough (has ribosomes)
Location: attaches from cell membrane to nuclear
membrane
Rough E.R.

12. Cell Parts and Functions
Ribosome
Makes proteins
Location: in cytoplasm or
Attached to E.R.
Vacuole
Stores food and water
Location: in cytoplasm

13. Vacuole

14. Cell Parts and Functions
Lysosome
Contains digestive enzymes
Destroys bacteria, old cell parts…
Location: in cytoplasm
Centrioles
Helps the cell to divide
Location: in cytoplasm

16. Cell Parts and Functions
Cytoplasm
Gel-like substances, holds all
Organelles in cell
Location: in cell
Chromatin/Chromosomes
Contains genetic information/traits
Location: in nucleus

17. Cell Parts and Functions
Cilia
Short hair-like projections
Used for movement
Location: outside of cell
Flagella
Long whip-like tail
Used for movement
Location: outside of cell

19. FLAGELLA

20. Cell Structures and Functions
Chloroplast
Traps suns energy and
Makes food
Location: in plant cells

21. Cell Wall
Cell Wall
Protects and supports plant
Cells
Prevents water loss
Cellulose
Location: outer layer of plant cells

22. CYTOSKELETON
Function: Support structure of cell and
transport materials/organelles throughout
the cell.
The highway of the cell.
Made of Microtubules (thin hollow
cylinders) and Microfilaments (thin solid
cylinders)
Location: Inside the cell

23. CYTOSKELETON

24. Cell Structures and Functions
Plastids
Stores extra food in
Plant cells
Location: in plant cell
