  parent May result when a piece breaks off from
  the parent organism or when the parent organism
  divides in two

39
Characteristics of Living Things

• Living things respond to their environment.
• Stimulus signal to which an organism responds
• External come from the environment outside the
  organism ex. Light, temperature (plant roots
  respond to gravity by growing down)

Lets practice

• Our cat had kittens yesterday.
• Our dog was much smaller when it was a puppy.
  
• When you look at a piece of a plant leaf under a
  microscope, you see many smaller divisions.
• My children look a lot like their father.
