Cell Parts and Functions
Cell Membrane
Protects the cell
Lets things in and out of the cell
Location: around the cell
Nucleus
Control center
Location: inside the cell,
near the center
Cell Parts and FunctionsNucleolus (Nucleoli)Makes ribosomesLocation: inside the nucleus (dark spot)
Nuclear MembraneProtects nucleusLets things in/out of nucleus (pores)Location: around nucleus
cell
Cell Parts and FunctionsMitochondria
Makes energy/powerhouse
Location: in cytoplasm
Golgi Bodies/Apparatus
Packages and secretes
(gets rid of) waste
Location: in cytoplasm
Mitochondria
GOLGI APPARATUS
Cell Parts and Functions
Endoplasmic Reticulum (E.R.)Transports materials and sends messages to all parts of the
cell
Two types: smooth and rough (has ribosomes)
Location: attaches from cell membrane to nuclear membrane
Rough E.R.
Cell Parts and Functions
Ribosome
Makes proteins
Location: in cytoplasm or
Attached to E.R.
Vacuole
Stores food and water
Location: in cytoplasm
Vacuole
Cell Parts and Functions
Lysosome
Contains digestive enzymes
Destroys bacteria, old cell parts…
Location: in cytoplasm
Centrioles
Helps the cell to divide
Location: in cytoplasm
Cell Parts and Functions
Cytoplasm
Gel-like substances, holds all
Organelles in cell
Location: in cell
Chromatin/Chromosomes
Contains genetic information/traits
Location: in nucleus
Cell Parts and FunctionsCiliaShort hair-like projections Used for movementLocation: outside of cell
FlagellaLong whip-like tailUsed for movementLocation: outside of cell
FLAGELLA
Cell Structures and FunctionsChloroplast
Traps suns energy and
Makes food
Location: in plant cells
Cell Wall
Cell Wall
Protects and supports plant
Cells
Prevents water loss
Cellulose
Location: outer layer of plant cells
CYTOSKELETONFunction: Support structure of cell and
transport materials/organelles throughout the cell.
The highway of the cell.
Made of Microtubules (thin hollow cylinders) and Microfilaments (thin solid cylinders)
Location: Inside the cell
CYTOSKELETON
Cell Structures and Functions
Plastids
Stores extra food in
Plant cells
Location: in plant cell
