NucleusControl centerLocation: 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 FunctionsMitochondriaMakes energy/powerhouseLocation: in cytoplasm

Golgi Bodies/ApparatusPackages and secretes (gets rid of) wasteLocation: in cytoplasm

Mitochondria

GOLGI APPARATUS

Cell Parts and Functions

Endoplasmic Reticulum (E.R.)Transports materials and sends messages to all parts of

the cellTwo types: smooth and rough (has ribosomes)Location: attaches from cell membrane to nuclear

membrane

Rough E.R.

Cell Parts and Functions

RibosomeMakes proteinsLocation: in cytoplasm orAttached to E.R.

VacuoleStores food and waterLocation: in cytoplasm

Vacuole

Cell Parts and Functions

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 FunctionsChloroplastTraps suns energy and Makes foodLocation: in plant cells

Cell Wall

Cell WallProtects and supports plantCellsPrevents water lossCelluloseLocation: outer layer of plant cells

CYTOSKELETON

Function: 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
