Description
Study Questions Chapter 3 - 1. List and briefly describe the six main functions of the cell. (6 marks) - cell metabolism and energy use: the chemical reactions that occur within cells are collectively called cell metabolism, the energy is used for multiple functions - synthesis of molecules: cells synthesize various types of molecules, proteins, lipids etc - communication: produce and receive chemical and electrical signals - reproduction and inheritance: each cell contains a copy of the genetic info of the indvidual 2. Draw the cell illustrating the following organelles: 

Nucleus, Nucleolus, Cytoplasm, Rough Endoplasmic Reticulum, Ribosome, Secretory Vesicle, Lysosome, Mitochondria, Cell Membrane and Gogli Apparatus. (5 marks) 3. Describe the functions of each of the following organelles:

Nucleus, Nucleolus, Cytoplasm, Rough Endoplasmic Reticulum, and Ribosome. (5 marks) - Nucleus: organelle containing the most genetic material of the cell - Nucleolus: rounded, dense, well-defined nuclear body with no surrounding membrane; subunits of ribosomes are manufactured within the nucleolus - Cytoplasm: cellular material surrounding the nucleus - Rough Endoplasmic Reticulum: many ribosomes attach here, site of protein synthesis - Ribosome: small, spherical, cytoplasmic organelle where protein synthesis occurs 4. Describe the functions of each of the following organelles:

Secretory Vesicle, Lysosome, Mitochondria, Cell Membrane and Gogli Apparatus. (5 marks) - secretory vesicle: contains materials produced in the cell; secreted by exocytosis - lysosome: contains enzymes that digest material taken into the cell - mitochondria: site of aerobic respiration and major site of ATP synthesis - cell membrane: encloses cytoplasm, forms boundary between material inside cell and outside - gogli apparatus: stacks of flattened sacks that collect, modify, package, and distribute proteins and lipids 5. Describe separately, the effects of placing a
