Ch. 1 Lesson 1What are

the building blocks of

life?

cell

microscope•tool that makes objects seem larger than they really are

cell•smallest unit of a living thing that can perform all life processes:

1. Get & use energy

2. Grow & develop

3. Get rid of waste

4. Reproduce

5. React to the environment

cell membrane cell’s outer border-

controls whatpasses in &

out of cell

nucleus controls cell’s

activities

cytoplasm

watery gel

chloroplastschloroplasts(only in plants)(only in plants)

uses Sun’s energy

to make sugar & oxygen

It gets and uses energy, it grows and it reacts to

its environment.
