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
cell wallcell wall(only in plants)(only in plants)
outside cell membrane gives extra support
& protection
