a. Nucleus- controls cell function (has DNA).

Eukaryotic cells have a membrane bound nucleus that contains genetic information and directs activities of the cell. They also have membrane bound organelles. Ex.: Plants, Animals, Fungus , Algae.

  1. Eukaryotic cells have a membrane bound nucleus that contains genetic information and directs activities of the cell. They also have membrane bound organelles. • Ex.: Plants, Animals, Fungus, Algae

  2. 1. Eukaryotic cells have organelles- cell structures thatperform specific functions. Animal cells have: a. Nucleus- controls cell function (has DNA). b. Nucleolus- inside nucleus- makes ribosomes.

  3. b. Nucleolus- inside nucleus- makes ribosomes. c. Endoplasmic Reticulum- Cellular chemical reactions and protein packaging. d. Ribosomes- synthesizes (makes) proteins.

  4. d. Ribosomes- synthesizes (makes) proteins. e. Golgi Apparatus- modifies proteins and other substances. It sorts, packages and transports them where they need to go (using vesicles).

  5. e. Golgi Apparatus- modifies proteins and other substances. It sorts, packages and transports them where they need to go (using vesicles). • Mitochondria- makes energy for the cell transforms glucose and other substances into ATP.

  6. f. Mitochondria- makes energy for the cell transforms glucose and other substances into ATP. g. Lysosomes- digests wastes, bacteria and old cell parts.

  7. g. Lysosomes- digests wastes, bacteria and old cell parts. h. Vacuoles- storage compartments for waste or needed nutrients. In plants vacuoles are larger and store water.

  8. h. Vacuoles- storage compartments for waste or needed nutrients. In plants vacuoles are larger and store water 2. All cells have a cell membrane- the phospholipid bilayer that regulates what moves into and out of the cell.

  9. 2. All cells have a cell membrane- the phospholipidbilayer that regulates what moves into and out of thecell. • All cells have cytoplasm- the gelatinous fluid that suspends the organelles and a cytoskeleton, a framework of protein fibers that supports the cell.

  10. 3. All cells have cytoplasm- the gelatinous fluid that suspends the organelles and acytoskeleton, a framework of protein fibers that supports the cell. Plant Cell vs. • Chloroplasts For photosynthesis • Large vacoules • Cell Wall For structural support Animal Cells • No chloroplasts • Small vacuoles • No cell wall
