Correct answer: It does NOT contain ribosomes and is
involved in manufacturing various lipid molecules and steroid hormones
Question : What is the golgi apparatus?
Correct answer: flattened stacks that process, sorts,
package, and deliver proteins and lipids from the ER (Chemical processing and packaging center)
Question : What is the mitochondria?
Correct answer: Powerhouse of the cell; releases energy
from food molecules and transforms energy into ATP
Question : What is a lysosome?
Correct answer: Sewer system of the cell (destroys worn
cell parts); produced by golgi apparatus
