The Parts of the Cell
The Nucleus
--nuclear envelope
-- chromatin
--nucleolus
I am a reticulated python. Ask me what I have to do with the endoplasmic reticulum.
Endoplasmic Reticulum - Transport
Golgi Apparatus
- delivery system
Cis Face | Trans Face
Cisternae (folds)
Vesicles - package to be delivered
Ribosomes - Sites of Protein Synthesis
large
subunit
small
subunit
Each ribosome has a large and small subunit
Messenger RNA is threaded through the ribosomes
Transfer RNA builds a protein based on the code of the mRNA
Lysosomes - Intracellular Digestion Centers
TAY-SACHS disease – What do lysosomes have to
do with this deadly disease?
Other Organelles
-- Peroxisomes – result in hydrogen peroxide, broken down
by catalase
-- Vacuole -- mainly storage or specific functions (contractile
vacuole)
-- Plant cells have a CENTRAL VACUOLE - used for storage
and help to maintain hydrostatic pressure
Energy Related Organelles
Mitochondria - The Cell's Chemical Furnaces, produces ATP
Chloroplasts - Where Photosynthesis Takes Place
What do these organelles have in common?
What happens if your mitochondria don’t work?
Mitochondrial Disease Video
Why is mitochondrial disease
so devastating to children?
Consider the mitochondria
have their own DNA separate
from the parental DNA. How
could you cure this disease?
Cytoskeleton
How do cells maintain their shape?
Microfilaments (actin filaments)
Microtubules - form the spindle during cell division
Centrioles – used during cell division to move and separate chromosomes, only found
in animal cell
How do they move?
- pseudopod
- cilia
- flagella

Figure 4.7b
Show, Don't Tell
Each person will get a cell concept . For your concept,
design a picture that goes with it and a GESTURE for the
idea.
Be prepared to share your pictures and gestures with the
class. Your classmates will use your picture and your
gesture to guess what your concept was.
It’s like playing a twisted form of charades! You should be
able to draw your picture on the fly, on the board, but have a
plan in place before you go up there.
