All bacterial cells are prokaryotic cells, so they lack a nucleus and the membrane-bound organelles seen in eukaryotes. That one sentence answers most homework prompts, quiz items, and lab checkoffs. Still, the terms can feel slippery when you start naming cell parts. This page keeps it clean, then builds the full picture without the fluff.

No, bases aren’t always negatively charged; many are neutral, while many conjugate bases carry a negative charge. If you’ve seen hydroxide written as OH−, it’s easy to link “base” with “negative.” That link is half right, half a trap. In chemistry, “base” describes what a substance does in a reaction, not a single charge it

Yes, ball pythons are constrictors that subdue prey by coiling and applying pressure, not by venom. People call ball pythons “gentle” snakes, yet they still hunt with a coil. If you typed are ball pythons constrictors? into a search bar and got mixed answers, the confusion usually comes from how the word “constrictor” gets used.

No, bacteriophages that target bacteria aren’t known to infect humans, but contaminated products and immune reactions can cause issues. Bacteriophages (often called phages) are viruses that infect bacteria. They’re common on food, in water, and inside the human gut. If you’re asking whether they can hurt people, the usual answer is calm: a typical phage

Yes, bacteria are single-celled organisms, even when many cells stick together in colonies, films, or chains. You’ve seen it in textbooks: bacteria are “one-celled.” Then you spot a petri dish with a thick mat, or a microscope view packed with threads, and the question pops up again: are bacteria single celled organisms? The answer is

Bacteria are usually larger than viruses, often by 10× to 100× in width, with a few rare outliers at each end. If you’ve ever mixed up bacteria and viruses because both are “too small to see,” you’re not alone. If you typed are bacteria smaller than viruses?, this clears it up. They live on different

No, bananas are mostly simple carbs, with fiber and resistant starch that behave more like complex carbs. Bananas sit in a funny spot in carb talk. If you’re asking “are bananas a complex carbohydrate?”, you’ve heard mixed takes. They’re a fruit, so many people file them under “sugar.” Yet you’ll also hear bananas called a

Bacterial cells are prokaryotic cells, which means they don’t have a membrane-bound nucleus or membrane-bound organelles. If a worksheet asks “are bacterial cells eukaryotic or prokaryotic?”, the safest move is to lock onto one trait: bacteria lack a true nucleus. The terms can feel like “simple” versus “complex,” and that mental shortcut leads people astray.

Yes, bacteria are made of cells—each bacterium is one living cell that can grow, take in food, and divide. You’re not alone if this question trips you up. Bacteria are tiny, so it’s easy to lump them in with “germs” as a single idea. Science draws a sharper line: some germs are cells, some aren’t,

Most bacteria carry a circular chromosome, but some species use linear chromosomes, so the shape depends on the bacterium. You’ve probably seen the textbook line: bacteria have a single circular chromosome. It’s a tidy rule, and it’s often true in labs and in genome browsers. Biology still makes room for exceptions.
