Warm-Up

1
Warm-Up

• Name 3 living things and 3 nonliving things in
  this room.

2
6 Characteristics of Living Things

• Living things have cells.
• Living things sense and respond to change.
• Living things reproduce.
• Living things contain genetic material.
• Living things use energy.
• Living things grow and develop.

3
Living things have cells

• Cell a membrane-covered structure that contains
  all of the materials necessary for life!
• Discovered by Robert Hooke
• Most can only be seen with a microscope.
• Unicellular an organism made up of only one
  cell.
• Multicellular an organism made up of more than
  one cell.

4
Living things sense and respond to change

• Stimulus anything that causes a reaction or a
  change in an organism.
• Example Your pupils become smaller in bright
  light.
• Example The touch of an insect causes the Venus
  Flytrap to close.
• Example Colder temperature and less water
  results in leaves wilting.
• Homeostasis the maintenance of a constant
  internal state in a changing environment.

5
Living things sense and respond to change

• Give a new example of how an organism senses and
  responds to changes in its environment.

6
Living things reproduce

• Organisms make more organisms similar to
  themselves.
• There are two ways in which an organism can
  reproduce
• Sexual Reproduction two parents produce
  offspring. Offspring share characteristics of
  both parents.
• Asexual Reproduction one parent produces
  offspring. Offspring are identical to parents.

7
Living things reproduce

• What type of reproduction is cloning an example
  of?
• Can you think of an organism that reproduces
  asexually?

8
Living things contain genetic material

• Genetic material is found inside of cells (DNA is
  the genetic material in humans)
• DNA Deoxyribonucleic acid
• DNA controls the structure (how they are made)
  and function (what they do) of cells.
• DNA is passed from parent to offspring during
  reproduction.
• Heredity the passing of traits from parent to
  offspring.

9
Living things contain genetic material

• Have DNA which controls the structure and
  function of cells

10
Living things use energy

• Organisms need energy to carry out life
  activities.
• For example
• Making food
• Breaking down food
• Moving materials in and out of cells
• Metabolism all chemical activities that occur in
  an organism.

11
Living things grow and develop

• Grow an organism gets larger
• Develop an organism changes.
