Fundamental Characteristics of prokaryotic cell.
Don’t have organized nucleus and other membrane-bound organelles.
DNA is found in a central part of the cell called the nucleoid.
The cell wall of a prokaryote acts as an extra layer of protection, helps maintain cell shape, and prevents dehydration.
Prokaryotic cell size ranges from 0.1 to 5.0 m in diameter.
The small size of prokaryotes allows quick entry and diffusion of ions and molecules to other parts of the cell.
Primary properties that define life and living things
Cellular organization, Reproduction, Metabolism, Response to stimuli, Growth and development, and Adaptation through evolution are the important properties that define life and living things.
