Organelle Notes. (1) Nucleus. FUNCTION: Stores DNA / Chromosomes Covered in Nuclear Envelope Nucleolus makes ribosomes “Controls” cell STRUCTURE: (see next slide). (2) Endoplasmic Reticulum. FUNCTION: Lipid production + assembly Protein assembly Lipid + Protein export
E N D
(1) Nucleus • FUNCTION: • Stores DNA / Chromosomes • Covered in Nuclear Envelope • Nucleolus makes ribosomes • “Controls” cell • STRUCTURE: (see next slide)
(2) Endoplasmic Reticulum • FUNCTION: • Lipid production + assembly • Protein assembly • Lipid + Protein export • STRUCTURE: (see next slide)
(3) Ribosome • FUNCTION: • Protein production • STRUCTURE:
(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 • FUNCTION: • Convert chemical energy stored in food, into ATP • Undergo Cellular Respiration • STRUCTURE: (see next slide)
(6) Chloroplast • FUNCTION: • Convert light energy from the sun, into stored energy in food. • Undergo photosynthesis • STRUCTURE: (see next slide)
(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 • FUNCTION: • Contain catalase • Break down hydrogen peroxide. • STRUCTURE:(looks like lysosome)
(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 • FUNCTION: • Storage sac for materials like water, salts, proteins and carbohydrates. • Plants use them to maintain structure. • STRUCTURE: (see next slide)
