Cells with cell chemicals and genetic material having no defined organelles and are all enclosed within a cell wall are called prokaryotes. Organisms in this group are small in size and are mainly bacteria. Ribosomes in these small cells are also small and ‘free floating’. DNA in prokaryotic cells is in the form of a circular strand and not as a chromosome.
Have an awesome day! :)

It is a survival mechanism evolved by the body used in the objective to escape danger.
The most characteristic of the plants which can fulfill is the use of energy, maintain homeostasis,and composed of the cells.
<u>Explanation:</u>
HOMEOSTASIS: It is the property of the living organisms in which the internal system is kept in balance. Plants stay cools in the desert heat through their reflective surface, reduced leaves or the leaves that are parallel to the sun.
USES OF ENERGY: The plant uses the energy of the sun to change the water and the carbon dioxide into the sugar called glucose and it is used by the plants for the energy.
CELLS: It has cell walls, cell membranes, and it is composed of cellulose, pectin, hemicellulose. The cell in the plants varies from species to species.
