Answer 1

Explanation:

Summary. Bacteria are unicellular organisms that have a variety of sizes, shape, and envelope structures. The minimal requirements are cytoplasm, a cell membrane that surrounds the cytoplasm, and a DNA chromosome. A few have internal structures such as vacuoles and storage bodies but none have true organelles.Bacteria are prokaryotes, lacking well-defined nuclei and membrane-bound organelles, and with chromosomes composed of a single closed DNA circle. They come in many shapes and sizes, from minute spheres, cylinders and spiral threads, to flagellated rods, and filamentous chains.
