 
 <prompt> Which one get plenty pass, bacilli or bacillus? Given di previous question, write a context wey contain di answer. E fit be 1 - 20 sentences. Context: <response>: Most bacterial species dey either spherical, wey dem dey call cocci (singular coccus, from Greek kókkos, grain, seed), or rod-shaped, wey dem dey call bacilli (singular bacillus, from Latin baculus, stick). Elongation dey linked to swimming. Some bacteria, wey dem dey call vibrio, get shape like slightly curved rods or comma-shaped; others fit be spiral-shaped, wey dem dey call spirilla, or tightly coiled, wey dem dey call spirochaetes. A small number of species even get tetrahedral or cuboidal shapes. More recently, some bacteria wey dey deep under Earth's crust don dey discovered wey dey grow as branching filamentous types with a star-shaped cross-section. The large surface area to volume ratio of this morphology fit give these bacteria advantage for nutrient-poor environments. This wide variety of shapes dey determined by the bacterial cell wall and cytoskeleton, and e dey important because e fit influence the ability of bacteria to acquire nutrients, attach to surfaces, swim through liquids and escape predators.
