Question

diagrams - any of the following diagrams (or similar diagrams) could potentially be on your final exam. they could be part of a mc question, part of a short answer question, or be a diagram to be labeled. there will be a wordlist provided with the diagrams.

Explanation:

Identify prokaryotic cell structures (left diagram)

• A: Capsule / Cell wall (outer protective layers)
• B: Pili / Fimbriae (hair-like appendages)
• C: Flagellum (tail-like structure for movement)
• D: Cell membrane / Plasma membrane (inner boundary layer)
• E: Ribosome (small dots in cytoplasm)
• F: Nucleoid / DNA (circular genetic material)
• G: Cytoplasm (fluid filling the cell)

Identify eukaryotic cell structures (right diagram)

• A: Nucleus (nuclear envelope/membrane)
• B: Nucleolus (dense region inside nucleus)
• C: Chromatin / DNA (inside nucleus)
• D: Rough Endoplasmic Reticulum (studded with ribosomes)
• E: Golgi apparatus (stacked membrane structure)
• F: Cytoplasm / Cytosol (fluid matrix)
• G: Lysosome / Peroxisome (small vesicle)
• H: Ribosome (free-floating or on ER)
• I: Mitochondrion (oval with folded inner membrane)
• J: Plasma membrane (outer boundary)
• K: Microtubules / Cytoskeleton (structural fibers)
• L: Centrosome / Centriole (barrel-shaped organelle)
