Cell organelles


Published on

This is a simple presentation on Cell organelles made for students.My message to all the students is that this has been made just to give you an idea so that you can learn something and can make a new presentation yourself.This is also a presentation made by a 14 year child.This is specially made for the students of 8th and 9th.Learn from it.

Cell organelles

  2. 2. In  cell biology , an organelle  is a specialized subunit within a  cell  that has a specific function, and is usually separately enclosed within its own  lipid bilayer .
  3. 3. The Cell Organelles are as follows : <ul><li>Cell Membrane </li></ul><ul><li>Cell Wall </li></ul><ul><li>Nucleus </li></ul><ul><li>Cytoplasm </li></ul><ul><li>Endoplasmic Reticullum </li></ul><ul><li>Ribosomes </li></ul><ul><li>Golgi Bodies </li></ul><ul><li>Mitochondria </li></ul><ul><li>Plastids </li></ul><ul><li>Vacuoles </li></ul><ul><li>Lysosomes </li></ul>
  4. 4. Cell Membrane <ul><li>Outer boundary of cell </li></ul><ul><li>Protects the cell </li></ul><ul><li>Controls what enters and leaves the cell </li></ul>
  5. 5. Cell Wall <ul><li>Only found in plant cells </li></ul><ul><li>Adds protection and support </li></ul><ul><li>Made of cellulose. </li></ul><ul><li>Allows water and dissolved substances to pass through. </li></ul>
  6. 6. The Nucleus <ul><li>Controls most activities in the cell </li></ul><ul><li>Contains all genetic information in the form of DNA. </li></ul>
  7. 7. Cytoplasm <ul><li>Clear fluid within cell that contains all organelles </li></ul><ul><li>Moves materials throughout the cell </li></ul>
  8. 8. Endoplasmic Reticulum <ul><li>Series of folded membranes that form sacs or tubes </li></ul><ul><li>Rough ER has ribosomes attached </li></ul>
  9. 9. Ribosomes <ul><li>Transports materials between the cytoplasm and nucleus </li></ul><ul><li>Makes proteins in the cell </li></ul><ul><li>May be free in cytoplasm or attached to ER </li></ul><ul><li>Proteins are vital to life- all cells must produce them </li></ul>
  10. 10. Golgi Bodies <ul><li>Saclike membranes used for storing/ packaging of chemicals </li></ul><ul><li>Cells that make saliva or mucus have many Golgi bodies </li></ul>
  11. 11. Mitochondria <ul><li>Energy producers </li></ul><ul><li>Powerhouse of the cell </li></ul><ul><li>Sausage-shaped </li></ul><ul><li>Many mitochondria in muscle cells </li></ul>
  12. 12. Plastids <ul><li>Only found in plants/ algae </li></ul><ul><li>Contain food or pigments </li></ul><ul><li>Leucoplasts store food </li></ul><ul><li>Chloroplasts contain the pigment chlorophyll </li></ul>
  13. 13. Vacuoles <ul><li>Store food, water, or waste materials </li></ul><ul><li>Plant cells have large vacuoles </li></ul>
  14. 14. Lysosomes <ul><li>Found in Golgi bodies </li></ul><ul><li>Contain digestive enzymes to digest unwanted particles </li></ul><ul><li>Help white blood cells to destroy bacteria </li></ul>
