Answer:
1. Method of energy production
2. Size
3. Motility
4. Shape
Step-by-step explanation:
Prokaryotes are the unicellular organisms that lack a well-defined nucleus and other membrane-bound organelles. However, they differ from each other significantly. Prokaryotes may be aerobic or anaerobic that derive the energy by aerobic cellular respiration or fermentation. The aerobic prokaryotes may be obligate or facultative aerobes. Likewise, anaerobic prokaryotes may be obligate or facultative anaerobes.
The size of prokaryotes ranges from 0.1 to 5 micrometers. various species of prokaryotes differ significantly from each other in their size and shape. For example, bacteria may be rod-shaped bacillus, spiral, spherical coccus, etc. Prokaryotes may be motile or non-motile. The motile prokaryotes may move through gliding, swimming, swarming or floating and may use various appendages such as flagella, pili, etc.
