Document Summary
Q: one thing that e. coli and other bacteria have in common with eukaryotes is the presence of: chloroplasts, mitochondria, nucleus, ribosomes. Concept 27. 1: structural and functional adaptations contribute to prokaryotic success. The three most common are spheres (cocci), rods (bacilli), and spirals (spirilli) Maintains cell shape, provides physical protection, prevents cell from bursting in a hypotonic environment. A capsule (a sticky layer of polysaccharide or protein) may cover the cell wall of many prokaryotes. Fimbriae and pilli allow prokaryotes to stick to their substrate or other individuals in a colony. Q: gram-negative bacteria have ___ peptidoglycan than gram-positive cells and their cell walls are ___ complex structurally: more; more, more; less, less; less, less; more. In a heterogeneous environment bacteria exhibit taxis (ability to move toward or. Structurally different from eukaryotic flagella away from certain stimuli) Some do have specialized membranes that perform metabolic functions. Prokaryotic chromosome (circular dna found in the nucleoid region)
