Prokaryotic VS Eukaryotic: Unit 1 Cell Structure (Chapter 4)

Plasma / Cell Membrane: Prokaryotic (1/9)

Controls entry/exit; maintains homeostasis 

Cell Wall: Prokaryotic (2/9)

Provides shape, protection, prevents bursting

Slime Layer / Capsule: Prokaryotic (3/9)

Protects from drying; aids attachment; shields from immune system 

Sex Pili (Pilus): Prokaryotic (4/9)

DNA transfer (conjugation); attachment

Cytoplasm: Prokaryotic (5/9)

Site of chemical reactions; holds molecules and ribosomes

Nucleoid: Prokaryotic (6/9)

Stores genetic information; controls cell activities

Plasmid (DNA): Prokaryotic (7/9)

Extra genes (e.g., antibiotic resistance); transferable

Ribosomes (70S): Prokaryotic (8/9)

Protein synthesis

Flagellum: Prokaryotic (9/9)

Movement; propels the cell
