Chapter 4b: A Tour of the Cell (4.6-23 Cell Organelles)
Cell Structures Involved in Manufacturing and Breakdown
Describe the structure and functions of the nucleus, endomembrane system, smooth and rough
endoplasmic reticulum, Golgi apparatus, lysosomes, and vacuoles.
Energy-Converting Organelles
Compare the structures and functions of chloroplasts and mitochondria.
Describe the evidence that suggests that mitochondria and chloroplasts evolved by endosymbiosis.
Internal and External Support: The Cytoskeleton and Cell Surfaces
Compare the structures and functions of microfilaments, intermediate filaments, and microtubules.
Relate the structure of cilia and flagella to their functions.
Describe examples of environmental and genetic causes of infertility in men.
Relate the structure of the extracellular matrix to its functions.
Compare the structures and functions of tight junctions, anchoring junctions, and gap junctions.
Relate the structure of plant cell walls to its functions.
Functional Categories of Cell Structures
Describe the four functional categories of organelles in eukaryotic cells.
Describe the three fundamental features of all organisms.
