Transcript Cell Structure and Function

Cell Structure and Function
10 Parts of a Typical Animal Cell
1. Cell Membrane
Cell Membrane
-controls what moves in and out of the
the cell
-has “selective permeability”
-gives the cell it’s shape
2. Cytoplasm
Cytoplasm
-a gel-like liquid that fills the cell
-keeps organelles in place but also
allows them to move around
3. Nucleus
Nucleus
-the “control center” of the cell
-contains DNA
-largest structure in an animal cell
4. Nuclear Membrane
Nuclear Membrane
-a protective layer that surrounds the
nucleus
-has small pores that allow RNA and
ribosomes to move in and out of the
nucleus
5. Endoplasmic Reticulum
Endoplasmic reticulum
-located next to the nucleus
-a passageway for ribosomes and
other structures to move throughout
the cell
*smooth ER does not have ribosomes
*rough ER contains ribosomes
• 6. Ribosomes
Ribosomes
-small proteins that make more
proteins
-RNA
7. Golgi Apparatus
Golgi Apparatus
-packages proteins and other particles
that need to be removed from the cell
-small vessicles called “Golgi bodies”
form from the Golgi Apparatus
8. Lysosomes
Lysosomes
-get rid of broken or unused cell parts
-contains strong enzymes
9. Mitochondria
Mitochondria
-the “power house” of the cell
-supplies the cell with ATP energy
-can duplicate itself when the cell is in
need of energy
10. Cytoskeleton
Cytoskeleton
-provide strength and support in the
structure of the cell
*microtubules are like small tubes that
make other organelles such as
centrioles
*microfilaments are thin fibers that
make structures such as cilia or flagella
