Study Guide Unit 1: Cells Test 24-25

When you fall off your bike and damage skin on part of your body, some of your cells die. What is the reason why your skin eventually heals and grows back to look the same again?

• Your cut healed because all living things are made of cells through meiosis.

• Your cut healed because cells grow faster under bandages due to magical healing.

• Your cut healed because new cells are produced from other cells through the process of mitosis.

• Your cut healed because cells are the basic unit of life and are needed for everything.

Which instrument made it possible for the discovery and understanding of cells?

• the horoscope

• the telescope

• the stethoscope

• the microscope
