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
