  3. Back to Beginning End Plant Cell Chloroplast Golgi Body Mitochondrion Chromatin Cell Membrane Nucleus Cytoplasm Nucleolus Nuclear Membrane Endoplasmic Reticulum Cell Wall Vacuole Ribosome

  4. Back To Plant Cell Back to Animal Cell Nucleolus • Where ribosomes are created • DNA information is copied here • The prominent structure in the nucleus References: http://www.tvdsb.on.ca/westmin/science/sbi3a1/Cells/nucleus.htmhttp://www.cellsalive.com/cells/nucleus.htm

  5. Back To Plant Cell Back to Animal Cell Endoplasmic Reticulum • A series of membrane channels • Forms a tubular network throughout the cell • Transports chemicals within cells Reference: http://www.tvdsb.on.ca/westmin/science/sbi3a1/Cells/endo.htm

  6. Back To Plant Cell Back to Animal Cell Cytoplasm • Fluid environment of the cell • All other cell organelles reside in cytoplasm • Full of proteins that control cell metabolism Reference: http://www.cellsalive.com/cells/membrane.htm

  7. Back To Plant Cell Back to Animal Cell Chromatin • Hereditary information • Composed of long thin strands of DNA • Contains instructions that control heredity and cell metabolism Reference: http://www.tvdsb.on.ca/westmin/science/sbi3a1/Cells/nucleus.htm

  8. Back To Plant Cell Back to Animal Cell Golgi Body • Modifies chemicals to make them functional • Prominent in cells that secrete cell products like mucus • Secretes chemicals in tiny vesicles. Reference: http://www.cellsalive.com/cells/golgibody.htm

  9. Back To Plant Cell Back to Animal Cell Cell Membrane • Controls what substances came into and out of the cell • Acts as a boundary layer to contain cytoplasm • A fat layer between two protein layers that encloses cells Reference: http://www.tvdsb.on.ca/westmin/science/sbi3a1/Cells/membrane.htm

  10. Back To Plant Cell Back to Animal Cell Ribosome • Produces protein • Doesn’t have a membrane around it • Break into two different parts when not producing protein Reference: http://www.tvdsb.on.ca/westmin/science/sbi3a1/Cells/ribo.htm http://web.mit.edu/esgbio/www/cb/org/organelles.html

  11. Back To Plant Cell Cell Wall • Rigid structure of nonliving • material surrounding the cell membrane • Provides protection from injury • Made of cellulose • Only in plant cells Reference: http://www.tvdsb.on.ca/westmin/science/sbi3a1/Cells/cellwall.htm

  12. Back to Beginning End Animal Cell Nuclear Membrane Vacuole Nucleolus Chromatin GolgiBody CellMembrane Mitochondrion Endoplasmic Reticulum Centrosome Lysosome Cytoplasm Ribosome

  13. Back To Plant Cell Mitochondrion Back to Animal Cell • “Power house” of the cell • Shape varies, but is the size of bacteria • Gives energy to cell to move and divide REFERENCE http://www.cellsalive.com/cells/mitochon.htm Cytology and History: Cells and Tissues Classroom Consorta

  14. Back to Animal Cell Centrosome • Help in cell reproduction • Two centrosomes are perpendicular • Separate in own centrosomes to separate cell REFERENCE Cytology and History: Cells and Tissues Classroom Consorta http://www.cellsalive.com/cells/mitochon.htm

  15. Back to Animal Cell Lysosome • Organelle containing enzymes • In animal cells, but not often in plant • Breaks down food particles REFERENCE http://www.cellsalive.com/cells/lysosome.htm Cytology and History: Cells and Tissues Classroom Consorta

  16. Back To Plant Cell Back to Animal Cell Nuclear Membrane • Membrane envelope of nucleus • “Perforated by Nuclear Pore complexes” • Controls the molecules in and out of nucleus REFERENCE http://www.cellsalive.com/cells/nucleus.htm Cytology and History: Cells and Tissues Classroom Consorta

  17. Back To Plant Cell Back to Animal Cell Nucleus • Center of cell • Power house directs all cell activity • Provides cell with “unique characteristics” REFERENCE http://www.cellsalive.com/cells/nucleus.htm Cytology and History: Cells and Tissues classroom Consorta

  18. Back To Plant Cell Back to Animal Cell Vacuole • In both, but bigger in plants • Stores waste and water • It creates turgor pressure when full of water REFERENCE http://www.cellsalive.com/cells/vacuole.htm Cytology and History: Cells and Tissues classroom Consorta

  19. Back To Plant Cell Chloroplast • Only in plants • Contain chlorophyll giving green color • Makes food for the plants REFERENCE http://cellsalive.com/cells/chloropl.htm Cytology and History: Cells and tissues Classroom Consorta

  20. Back to Beginning Compare and Contrast End Plant Cell Animal Cell • Lysosome • Centrosome • Smaller Vacuoles • Have Chloroplasts • Cell Wall • Larger Vacuoles Both • Make up living things • Have eleven other organelles, such asthe mitochondrion, endoplasmic reticulum, and golgi bodies

  21. The End! Back to the Beginning! Leave!
