Six Requirements of Life An ORGANISM is any

Six Requirements of Life An ORGANISM is any form of life that has all 6 Characteristics of Life.

1 Made of Cells A cell is the basic unit of life. EX: Uni-cellular or Multi-cellular Plant Cells, Animal Cells, Bacteria & Protist

2 Obtain & Use Energy / Metabolism METABOLISM is the sum of physical & chemical processes in an organism. EX: Ingest (Consumer or Producer? ) Digest (Break down food molecules) Respiration/Photosynthesis Excretion (Get rid of waste) Make Energy (Mitochondria)

2 Obtain & Use Energy / Metabolism EXAMPLES

3 Grow & Develop EX: Physical Growth or Life Cycles

4 Reproduce EX: Sexual or Asexual (lay eggs, seeds, live birth, pollination) Pass on Genetic Information (DNA)

5 Respond to the Environment EX: Internally or Externally Animals sweat or shiver Plants wilt or freeze

6 Adapt to their Environment EX: Camouflage protects predators from prey, Wax coats protects against water loss.

Living Things Anything that can carry out ALL 6 characteristics of life. 1. Made of Cells 2. Obtain & Use Energy 3. Grows & Develops 4. Reproduce (passes genetic information) 5. Responds to the environment 6. Adapts to the environment

Once Living (DEAD) Something that at one point was part of a living thing. Made of dead cells Examples: stick, cotton, leaf, shell

NON-Living (Never been alive) NEVER part of a living thing, thus cannot pass genetic information. NOT made of cells Made of Atoms & Molecules Examples: water, air, rock, dirt
