Q

3 principles of cell theory

A
  • cells are the basic unit of structure and organization in organisms.
  • all living organisms are composed ofcells.

49
contains hydrolytic enzymes enclosed in a membrane.
lysosomes
50
# function: * used to digest food and protection * break down the cell when it dies
lysosomes
