Which of the following statements is always true?
a. All cells have a cell wall.
c. All cells contain a chloroplast.
b. All cells contain a nucleus.
d. All cells have a cell membrane.

Sagot :

The answer is letter D, the cells have a cell membrane . Not all cell have a cell wall, (only plant cell contains cellwall) . Not all cells contains chloroplast ( chloroplast present only in plant cell ) not all cell contains nucleus (prokaryotic cell is not containing nucleus) so, the always true is letter D, because it is known as semi permiable barrier and fluid mosaic model.
