Q

Vacuole

A

Storage compartments

Food vacuole

Contractile Vacuole

Central Vacuole

Q

Food vacuole

A

Store food

Q

Contractile Vacuole

A

Pumps H2O Out

Q

Central Vacuole

A

Holds H2O

Only in plants

Q

Vesicle

A

membrane sacs

Q

Cell wall

A

Only in plants

Additional layer of protection

Q

Cytoplasm

A

Liquid surrounding organelles in a cell

Q

Protein path

A

DNA in nuclear envelope

translated to mRNA

mRNA leaves through nuclear pores

meets ribot. forms peptide chains

leaves to rough ER

leaves to golgi

To lysosome
