NU545 CHAPTER 1 EXAM QUESTIONS AND ANSWERS
WITH COMPLETE SOLUTIONS GRADED A++ LATEST
UPDATE
Compare and contrast the two major classes of living cells
Eukaryotes and Prokaryotes
Define Eukaryotes
- Complex cellular organization
- Membrane-bound organelles
- Well-defined nucleus
- Higher animals, plants, fungi, and protozoa
Define Prokaryotes
- Characterized by lack of distinct nucleus
- Cyanobacteria, bacteria, and Rickettsiae
What are the 8 Cellular functions?
- Movement
- Conductivity
- Metabolic absorption
- Secretion
- Excretion
- Respiration
,- Reproduction
- Communication
What are the 3 general components of a cell?
- Plasma membrane
- Cytoplasm
- Intracellular organelles
Nucleus: Structure
- Nuclear envelope
- Nuclear pore complexes
- Nucleolus
- Ribonucleic acid (RNA)
- Deoxyribonucleic acid (DNA)
- Histone proteins
Nucleus: Function
Cell division and control of genetic information
Cytoplasm: Structure
- Cytoplasmic matrix
- Cytosol
- Cytoplasmic organelles
Cytoplasm: Function
, - Synthesis and transport
- Isolates and eliminates wastes.
- Metabolic processes
- Maintenance of cellular motility
Storage
Ribosomes: Structure
Ribonucleic acid (RNA) protein complexes; free vs. attached ribosomes
Ribosomes: Function
Synthesize proteins
Endoplasmic reticulum: Structure
Network of tubular or saclike channels; smooth vs. rough endoplasmic reticulum
Endoplasmic reticulum: Function
Site of protein synthesis; senses cellular stress
Golgi complex: Structure
- Flattened, smooth membranes
- Secretory vesicles and cisternae
- Proteins from the endoplasmic reticulum that are packaged in the Golgi complex
- Clathrin-coated vesicles
Golgi complex: Function
- "Refining plant" and directs traffic
- Processes, secretes, and releases substances, especially protein from cells
