A Tour of the Cell FUnctions

Multiple choice

Small structure that makes protein

Ribosome

Contains chromatin

Nucleus

Chromatin

DNA

Makes Cell Membranes

Rough ER

Sac of digestive enzymes

Lysosomes

Lipids manufactured here

Smooth ER

Carries secretions for export from cell

Transport Vesicle

Breaks down drugs and toxins in liver

Smooth ER

Cell Control Center

Nucleus

Numerous ribosomes give it its name

Rough ER

“Ships” products to plasma membrane, outside, or other organelles

Golgi Apparatus

May store water, needed chemicals, and wastes in plant cell

Central vacuole

Buds off from golgi apparatus

Transport vesicles

Defective in Tay Sachs disease

Lysosome

Proteins made and modified for secretion from cell

Golgi apparatus

Pumps out excess water from some cells

Contractile Vacuole

Nonmembranous organelle / structure

Ribosome

Takes in transport vesicles from ER and modifies their contents

Golgi Apparatus

Boundary between cell and its surroundings

Plasma membrane / cell membrane

Carries out mRNA instructions from the nucleus

ribosomes

How proteins and other substances get from ER to Golgi apparatus

transport vesicle

stores calcium in muscle cells

Smooth ER

“labels” and sorts molecules to be sent to different destinations

Golgi Apparatus

A digestive sac not related to other endomembrane structures

peroxisome

Digests food, wastes, foreign substances

Lysosome

Phospholipid bilayer with proteins controls flow in and out of cell

plasma membrane

Drug tolerance results from its enlargement

Smooth ER

Fuses with food vacuole and digests contents

Lysosomes

Structure in the nucleus where ribosomal RNA is made

Nucleolus

May be “free” or “bound”

Ribosome

Surrounded by an double-membrane envelope with the protein-lined pores

Nucleus

Looks like a stack of flattened sacs

Golgi apparatus

Sends transport vesicles loaded with proteins to the Golgi apparatus

Rough ER

Can store plant pigments and / or poisons

Central vacuole

Buds from here can become lysosomes

Golgi apparatus
