Diversity of Life (Unit 2)

What is life?

  • Life scientists agree that life on earth has existed for about 3.5 billion years. Humans have been on earth foe a very short time in comparision to all other life.
  • The cell is the chalice of life.

  • Cells all have the same basic requirements for survival.
  • Life is diverse.
  • MOST life is single-celled.
  • ALl organisms MUST adapt to their environment for survival.
