Chapter 3 Question 7
Short Answer Essay Question: Name the cellular organelles, and explain the function of each.
- Plasma membrane - defining the limits of the cell, "baggie"
- Nucleoli - sites where ribosomes are assembled
- Cytoplasm - site of most cellular activities, "factory area"
- Mitochondria - supplies most of the ATP, "powerhouses" of the cell
- Ribosomes - actual sites of protein synthesis in the cell.
- Endoplasmic reticulum - serves as a mini-circulatory system for the cell because it provides a network of channels for carrying substances (primarily proteins) from one part of the cell to another
- Golgi Apparatus - modify and package proteins in specific ways, depending on their final destination (sent by the rough ER via transport vesicles)
- Lysosomes - membranous "bags" containing powerful digestive enzymes. (breakdown bodies)
- Peroxisomes - "disarm" dangerous free radicals
- Cytoskeleton - acts as a cell's "bones and muscles" by furnishing an internal framework that determines cell shape, supports other organelles, and provide the machinery needed for intracelllular transport and various types of cellular movements.
- Centrioles - direct the formation of the mitotic spindle
