Presentation Transcript
1 nucleus
(1) Nucleus
  • FUNCTION:
    • Stores DNA / Chromosomes
    • Covered in Nuclear Envelope
    • Nucleolus makes ribosomes
    • “Controls” cell
  • STRUCTURE: (see next slide)
2 endoplasmic reticulum
(2) Endoplasmic Reticulum
  • FUNCTION:
    • Lipid production + assembly
    • Protein assembly
    • Lipid + Protein export
  • STRUCTURE: (see next slide)
3 ribosome
(3) Ribosome
  • FUNCTION:
    • Protein production
  • STRUCTURE:
4 golgi body apparatus
(4) Golgi Body / Apparatus
  • FUNCTION:
    • Modify, Sort & Package proteins
    • Take materials made @ ER  Package to be shipped to other areas of the cell, or to be secreted out of the cell!
  • STRUCTURE: (see next slide)
5 mitochondrion
(5) Mitochondrion
  • FUNCTION:
    • Convert chemical energy stored in food, into ATP
    • Undergo Cellular Respiration
  • STRUCTURE: (see next slide)
6 chloroplast
(6) Chloroplast
  • FUNCTION:
    • Convert light energy from the sun, into stored energy in food.
    • Undergo photosynthesis
  • STRUCTURE: (see next slide)
7 lysosome
(7) Lysosome
  • FUNCTION:
    • Filled with enzymes that digest/break down lipids, carbs, proteins and other molecules into smaller forms.
    • Digest “useless” cell parts.
  • STRUCTURE: (see next slide)
8 peroxisome
(8) Peroxisome
  • FUNCTION:
    • Contain catalase
    • Break down hydrogen peroxide.
  • STRUCTURE:(looks like lysosome)
9 centriole centrosome
(9) Centriole / Centrosome
  • FUNCTION:
    • Centrioles are unique to animal cells.
    • Centrioles organize DNA during replication + division.
    • Centrosomes produce microtubules like centrioles.
    • Centrosomes also help w/division in plant cells.
  • STRUCTURE: (see next slide)
vacuole
Vacuole
  • FUNCTION:
    • Storage sac for materials like water, salts, proteins and carbohydrates.
    • Plants use them to maintain structure.
  • STRUCTURE: (see next slide)
