Organisms

  1. 1. What is an Organism? <ul><li>An organism is a living thing </li></ul><ul><li>It is a collection of molecules that function as a whole </li></ul><ul><li>It has a barrier between itself and its environment </li></ul>
  2. 2. The Cell <ul><li>The basic unit of life is a cell </li></ul><ul><li>Cells are further broken into parts called organelles </li></ul><ul><li>Just as we have organs, cells have organelles </li></ul>
  3. 3. Single-Celled Organisms <ul><li>Some organisms only have one cell </li></ul><ul><li>Bacteria, that cause infections and certain diseases, are living things made of only one cell </li></ul>
  4. 4. Plants and Animals <ul><li>Organisms we are most familiar with have many cells </li></ul><ul><li>Our bodies have around 10 trillion cells </li></ul><ul><li>Plant cells and animal cells have many similarities and several differences </li></ul>
  5. 5. Animal Cells <ul><li>The center or “brain” of the cell is called the nucleus </li></ul><ul><li>Ribosomes take information from the cell’s nucleus and use it to create molecules for building new organelles or new cells </li></ul><ul><li>Mitochondria “power” the cell </li></ul>
  6. 6. Plant Cells <ul><li>Plant Cells are similar to animal cells except for a few differences </li></ul><ul><li>Plant cells have a cell wall to maintain shape </li></ul><ul><li>Plant cells have chloroplasts to absorb sunlight </li></ul>
  7. 7. What are the… <ul><li>Their cells are similar but what are some differences between plants and animals? </li></ul><ul><li>Can you name a few already? </li></ul>
  8. 8. Differences Between Plants and Animals <ul><li>Plants have roots </li></ul><ul><li>Plants absorb carbon dioxide and release oxygen </li></ul><ul><li>Plants do not move (from place to place) </li></ul><ul><li>Plants absorb sunlight for energy </li></ul><ul><li>Animals must eat and drink </li></ul><ul><li>Animals breathe in oxygen and release carbon dioxide </li></ul><ul><li>Animals do move </li></ul><ul><li>Most of animals’ energy comes from food and water </li></ul>
