Note these drawings of animal and plant cells. Which does
NOT have a cell wall outside it’s plasma membrane?
Fungi also have cell walls; so do some protists and some bacteria.
Cells walls are made of cellulose in plants, chitin in fungi,
peptidoglycan in eubacteria.
Cell walls extra support & extra protection for cells.
Cell walls protect cells from bursting and provide them
support against pressure (so they don’t get crushed).
Which kingdom (the only one) NEVER has cell walls?

Cells are like factories
Cytoskeleton—supports structure & provides ramps
for moving material like steel beams
Nucleus—control center due to the DNA—the main
office
Ribosome—makes proteins using blueprints from
DNA (like a machine in a factory)
Golgi/ER—modify proteins, like a customization shop
Chloroplasts—provide energy from sun, a solar power plant
Mitochondria—provide energy cell uses directly by
breaking down glucose (like an oil burning furnace)
If you order an automobile
with special paint, it’s added in the factory’s
customization department. What cell
organelles serve this customization
function for proteins?

True or false.
Cells that are involved in detoxification have lots
of SER because this network of tubes contains
the enzymes used to degrade toxins.
True (e.g., in the liver)
True or false: cells making large
amounts of proteins (like
hormones) for export would have
large amounts or RER and golgi.
True.
This targets the molecules in transport vesicles
to the membrane for exocytosis.
Which organelles are really
extensions of the cytoskeleton
(made of microtubules) that slide
via action of motor proteins and
allow cells to move?
Cilia—smaller—usually present in high numbers
Flagella—longer—usually present alone or in
pairs.
Peroxisomes are organelles that contain
hydrogen peroxide. This strong oxidizing agent
breaks up materials for cell defense (like
ingested bacteria or viruses). The enzyme
peroxidase (catalase) in the cytoplasm of cells
with peroxisomes serves to neutralize any
peroxide that escapes.
