_____ 1. This is the brain of the cell and where all of the genetic information is stored.
_____ 2. This organelle contains enzymes; it also defends the cell from invading bacteria and
virus.
_____ 3. This is the gel like material that holds all the other organelles in place inside the cell.
_____ 4. This organelle surrounds plant cells, gives protection and shape to the cell.
_____ 5. This organelle is responsible for processing, sorting and delivering proteins.
_____ 6. This organelle is a storage site for different materials inside the cell.
_____ 7. This organelle is found only in plant cells, it is responsible for carrying out
photosynthesis.
_____ 8. This organelle is attached to the ribosome, also links amino acids together to form
proteins, small organelle.
