Organelle Notes 1 Nucleus FUNCTION Stores DNA Chromosomes

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 • 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)

(10) Vacuole • FUNCTION: – Storage sac for materials like water, salts, proteins and carbohydrates. – Plants use them to maintain structure. • STRUCTURE: (see next slide)
