Cell Organelles!
Cells
Cells are the smallest living part that
make up all living things.
 You and most living things are made of
millions of cells.

QuickTime™ and a
TIFF (LZW) decompressor
are needed to see this picture.
Organelles
Cells contain even
smaller parts called
organelles.
 Organelles are
specialized to do one
function for the cell.
There are many
different kinds of
organelles


Two types of cells

Prokaryotes
Unicellular
 No membrane bound structures
 Bacteria

Protects the cell
Regulates movement of
substances in and out of
the cell
Found in plant and animal
cells
Can see under light
microscope


no
Rough ER vs. Smooth ER (functions):


ER: manufacters and transports
Rough ER: has ribosomes attached
• Make proteins

Smooth ER:
• Make lipids

holds the genetic material, called chromosomes, in
most cells.
chromosomes determine the characteristics of the
cell, or individual person, plant, mushroom, or any
living thing.
