Cell Definitions
Cell Membrane
• Found in all cells
• Controls or regulates
what goes in and out of
the cell. Outermost living
layer of the cell.
• The “Gate Keeper”
Cell Membrane Picture
Cell Wall
• Found in plants and some
bacteria.
• Outermost non-living
layer of the cell.
• Rigid layer.
Cell Wall Picture
Nucleus
• Found in eukaryotes
• Control & information
center of the cell.
• “The Brain”
Nucleus Picture
Cytoplasm
• Found in all cells
• Jelly-like substance found
inside the cell membrane.
• Allows cell parts to move more
freely.
Ribosome
• Found in all cells
• Makes all the proteins
produced by the cell.
Ribosome Picture
Endoplasmic Reticulum
• Found in eukaryotes.
• Transports materials
throughout the cell.
• “Highway”
Endoplasmic Reticulum
Picture
2 kinds of E.R.
• Smooth E.R.- Does not have
ribosomes.
• Rough E.R.-Has ribosomes
studded on it and produces
proteins.
Mitochondria
• Converts glucose (sugar)
into usable energy. The
site of cellular respiration.
• “Power House”
Mitochondria
Chloroplast
• Found in plant cells &
some bacteria.
• Puts CO and H O
together (uses energy
from the sun) to make
glucose.
*Photosynthesis*

Chloroplast Picture
Chromosomes (DNA)
• DNA is found in all cells
• Blueprint or master plan
of the cell. Structures in
the nucleus that contain
the genetic information
(DNA).
Chromosome picture
Golgi Complex
• Produce and release
products and are
especially common in
tissues which secrete
products. ( Glands )
• “Post Office”
Golgi Complex picture
Lysosome
• Digestive sac. Like the
stomach of the cell.
• “Little Stomach”
Lysosome Picture
Vacuole
• Storage sacs ( help in
digestion, waste and
food storage ). Help to
transport materials
throughout the cell.
• “the closet”
Vacuoles Picture
Vacuole Note:
• Plant cells have an extra large
water vacuole.
If you need more space,
continue your notes
onto the bottom of p. 17
and 18.
Nucleolus
• Small body within the
nucleus that makes
ribosomal rna.
Nucleolus picture
Centrioles
• Cylinder shaped
structures which help
separate chromosomes
during cell division.
Centriole Picture
Microtubules
• Hollow tube-like proteins
• Used to build structure(s) inside
the cell.
Nucleoplasm
• Jelly-like substance found
inside the Nucleus.
