Presentation Transcript

  1. Cell Organelles

  2. Animal Cells • The following slide are organelles typically found in the animal cells

  3. Cell Membrane • Cell Membrane- forms outer barrier to the cell • Function- provides protection and support for the cell and regulates movement of material into and out of cell

  4. Cytoplasm • Cytoplasm- clear thick jelly like substance between the Cell Membrane • Function- allows materials to move within the cell

  5. Mitochondria • Mitochondria-oval shaped with a wavy inner membrane • Function- (powerhouse) combines food substances like sugar and oxygen and produces energy and CO2 and H2O.

  6. Vacuoles • Vacuoles- not always found in an animal cell- substance filled sac in the cytoplasm • Function- vacuoles act as storage for both food and water as well as waste products.

  7. Lysosomes • Lysosomes- not always found in plant cell- small round structures involved with the digestive activities of the cell. • Function- contain enzymes that break down large food molecules into smaller ones.

  8. Endoplasmic Reticulum (ER) • Endoplasmic Reticulum (ER)-clear tubular passageways connected to the nuclear membrane • Function-transportation system of the cell, moves proteins to where they are needed.

  9. Ribosomes • Ribosomes- very small bodies attached to the inner lining of the ER made primarily of the nucleic acid RNA. • Function- produce the proteins needed by the cell

  10. Nucleus • Nucleus- large oval shaped organelle in the cell • Function- regulates or controls all the activities of the cell

  11. Parts of the Nucleus • Nuclear Membrane-very similar to the cell membrane regulates what moves into and out of the nucleus • Chromosomes-rodlike objects that contain all of a cells genetic material • Nucleolus-center within the nucleus believed to be where ribosomes are produced http://www.cartage.org.lb/en/themes/Sciences/Zoology/AnimalPhysiology/Anatomy/AnimalCellStructure/Nucleus/Nucleus.htm

  12. Organelles Unique to Plants

  13. Cell Wall • Cell Wall- strong and stiff outer layer of the plant cell. The cell wall is nonliving and is made of cellulose. • Function- protects and supports the cell, it enables trees to grow tall

  14. Large Central Vacuole • Large Central Vacuole-large water filled sac in plant cells • Function- in plants its main function is to store water, when the vacuole is low on water the cell becomes limp. When many cells become limp the plant will wilt. • Vacuole also store nutrients and waste products

  15. Chloroplast • Chloroplast- large green structures that float in the cytoplasm • Function- Chloroplasts contain a green pigment called chlorophyll, which captures energy from sunlight. That energy is then used to produce food. This is called photosynthesis.
