Within which structure of an animal cell does DNA replication take place?
a) vacuole
b) cell membrane
c) nucleus
d) ribosome

A pesticide that kills an insect by interfering with the production of proteins in the insect would most directly affect the activity of
a) ribosomes
b) minerals
c) chloroplast
d) mitochondria

Which organelle is correctly paired with its specific function?
a) Cell membrane - storage of hereditary information
b) Chloroplast - transport of materials
c) Ribosomes - synthesis of proteins
d) Vacuole - production of ATP

In a cell, all organelles work together to carry out
a) diffusion
b) active transport
c) information storage
d) metabolic processes

While viewing a slide of rapidly moving sperm, a student concluded that these cells require a large amount of energy. The organelles that most directly provide this energy are known as
a) vacuoles
b) ribosomes
