Title: Cell Structure


1
Cell Structure Function

2
Definition of Cell
  • A cell is the smallest unit that is capable of
    performing life functions.

3
Examples of Cells
Amoeba Proteus
Plant Stem
Bacteria
Red Blood Cell
Nerve Cell

Cell Parts
  • Organelles inside the cell

7
1. Nucleus
  • Controls cell processes contains DNA

2. Nuclear Membrane
  • Surrounds nucleus
  • Made of two layers
  • Provides support and protection for the nucleus

8
3. Chromatin
  • In nucleus
  • Made of DNA Protein which gives us chromosomes.
  • Contain instructions for traits characteristics
  • (looks like cooked spaghetti)

4. Nucleolus
  • Inside nucleus
  • Produces ribosomes for the cell (pink center in
    the drawing)

5.Nuclear Pores
  • Holes which allow material to move into or out of
    the nucleus.

11
6.Cytoplasm
  • Fluid-like mixture
  • Supports the cell organelles.

12
Endoplasmic Reticulum
  • 7.Smooth type (SER) lacks ribosomes. Contains
    enzymes to make lipids.
  • 8.Rough type (RER) (pictured) ribosomes embedded
    in surface. Lipids and proteins are assembled
    for export from the cell.

9.Ribosomes
  • Each cell contains thousands
  • Make proteins
  • Found on endoplasmic reticulum floating
    throughout the cell
  • VERY SMALL!!

10.Mitochondria
  • Powerhouse of the cell
  • Converts the energy in food to the energy that
    the cell can use (ATP).

15
11.Golgi Bodies
  • Modify, sort and package protein.

http//library.thinkquest.org/12413/structures.htm
l
16
12.Lysosome
  • Contain enzymes to break down proteins, fats, and
    carbs.
  • Garbage collector of the cell.

13. Vacuoles
  • Membrane-bound sacs for storage, digestion, and
    waste removal
  • Contains water solution
  • Help plants maintain shape

14. Chloroplast
  • Usually found in plant cells
  • Converts sunlight into plant food.
  • Where photosynthesis takes place

15.Centrioles
  • Aid in cell division only 2 in cell
  • Only found in animal cells.

20
Cytoskeleton
  • 16. Microtubules maintain cell shape and help
    form the spindle in cell division. (hollow)
  • 17. Microfilaments aid in movement and support.
    (solid)

21
18. Cell Wall
  • Provides support and protection for a plant cell.
    Found only in plants.

22
19. Cell membrane
  • Regulates what enters and leaves a cell
  • Provides protection and support for the cell
