Question 1

Cell wall

Answer 1

A rigid supporting layer that surrounds the cells of plants and some other organisms

Question 2

Nucleus

Answer 2

In cells, a large oval organelle that contains the cell’s genetic material in the form of DNA and controls many of the cell’s activities

Question 3

Organelle

Answer 3

Question 8

Mitochondria

Answer 8

Rod-shaped organelles that convert energy in food molecules to energy the cell can use to carry out its functions

Question 9

Endoplasmic Reticulum

Answer 9

An organelle that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another

Question 10

Golgi apparatus

Answer 10

An organelle in a cell that receives proteins and other newly formed materials from the endoplasmic reticulum, packages them, and distributes them to other parts of the cell

Question 11

Vacuole

Answer 11

A sac-like organelle that stores water, food, and other materials

Question 12

Chloroplast

Answer 12
