Question

Quizplus · Accepted Answer

Cells help to protect fragile biological molecules from the outside environment. A protective barrier is needed to keep molecules from diffusing away or being damaged by harsh environmental conditions. Cells are enclosed by a membrane that separates the interior of the cell from the outside environment, creating a controlled chemical environment. This enables chemical reactions to occur within the cell without interference from external factors.
