Aim: What are the functions of cell organelles?
• Ribosomes are responsible for assembling the proteins of the cell.
Endoplasmic Reticulum
• The endoplasmic reticulum is an extensive network of membranes composed of both regions with ribosomes and regions without ribosomes.
Golgi Apparatus
• responsible for manufacturing, warehousing and shipping certain cellular products, particularly those from the endoplasmic reticulum (ER).
• A Golgi complex is composed of flat sacs that are stacked.
Lysosome
• Lysosomes are membranous sacs of enzymes. These enzymes are typically hydrolytic and can digest cellular macromolecules

Centrioles function in cell division
• Centrioles are cylindrical structures that are composed of groupings of microtubules arranged in a 9 + 3 pattern.
Plant cell differences
• Cell wall
• Large vacuoles
• chloroplasts

Chloroplasts in the plant cell
• A typical plant cell (e.g., in the palisade layer of a leaf) might contain as many as 50 chloroplasts.
