BACTERIA!!!!


Ancient
bacteria…. Live
in extreme
environments, as
well as oceans,
soil


Most bacteria are
EUBACTERIA ….are
the ones people are
most familiar with.
Found everywhere!
Decompose dead
matter

2 Major TYPES of Cells
“Karyon” = nucleus
PRO = NO
PROkaryote = NO nucleus
EU = TRUE
EUkaryote = TRUE nucleus
Cell Wall
1. What TYPE of cell is this?
2. What is the name of this type of cell?
3. Can you label this cell?
1. What TYPE of cell are these?
2. Which one is a PLANT cell? ANIMAL cell?
3. How do you know?
A Vacuole stores Water, nutrients,
minerals, etc…
So, why is the vacuole so much larger in a plant cell?
Partly EMPTY Vacuole
vs
FULL Vacuole
CELL BOUNDARIES
1. Plasma/Cell
membrane:

Protection

It has pores in it…so it
Maintains
Homeostasis!
2. Cell wall:

Found in BOTH plant & animal cells

Protects & supports


Thicker/Inflexible
NOT found in animal cells
DIRECTION & ASSEMBLY
1. Nucleus:

Control center

Contains DNA (genetic mat.
that detetmine traits)

2. Ribosomes


Nuclear membrane surrounds
nucleus…porous
Make proteins
In cytoplasm & attached to ER
1. Chloroplasts


Contains green chlorophyll
for PHOTOSYNTHESIS!
Most common pigment containing plastid – there are
others.. Which gives leaves colors
NOTICE SURFACE AREA IN EACH
2. Mitochondria




“Powerhouses”;
Break down food molecules to
release energy
Found in BOTH plants & animals
Which has more mitochondria… muscle
or fat???
PACKAGING & TRANSPORT
1. Vacuole


2. Golgi Body

Storage area
Water, waste
Packages proteins for
transport to other cells or
other part of cell
Notice Surface Area
3. Endoplasmic
Reticulum:


Transports channels
Also help make lipids &
proteins
Lastly…

A Few NOTES on ISN p. 71
#1.
Organelles
A) CILIA
vs
short
many
Eukaryotic cells
Cilia on Protist
Respiratory Cilia in
Lung Epithelium
The cilia are bathed in nasal mucus. The mucus moisturizes the air but also, like fly paper,
filters dust , pollen, chemicals, bacteria and viruses that enter our nose as we breath. The
cilia are always refreshing the mucus coating of the nose. In coordinated waves, they
sweep a layer of mucus to the back of the nose every 5-8 minutes. The mucus then slips
into the throat where it is swallowed, rather than inhaled into the lungs. The acid of the
stomach destroys the harmful nasal debris.
