Prokaryotic cell

Simplified 2D textbook illustration of a prokaryotic cell shown in cross-section as a small oval or short rod-shaped bacterial cell. The cell lacks a membrane-bound nucleus and all other membrane-bound organelles. A thin plasma membrane is enclosed by an outer cell wall or smooth cell envelope, surrounding pale beige, light blue, green, tan, pink, or gray-blue lightly granular cytoplasm. Scattered throughout the cytoplasm are many tiny ribosome dots, and near the center is an irregular, diffuse to loosely coiled nucleoid region representing a single circular chromosome as a tangled DNA loop. The overall appearance is simple, smooth, schematic, and uncluttered.
