Write a single sentence, using no more than 25 words, to summarize each of the following cellular processes:
Diffusion

검증된 단계별 안내
1
Understand the concept of diffusion: it is the passive movement of molecules from an area of higher concentration to an area of lower concentration.
Identify the key components of diffusion, such as concentration gradient, passive transport, and the absence of energy requirement.
Formulate a concise sentence summarizing diffusion, ensuring it is no more than 25 words and includes the essential details of the process.
Review the sentence to confirm it accurately describes diffusion and adheres to the word limit.
Finalize the summary sentence: 'Diffusion is the passive movement of molecules down their concentration gradient, requiring no energy, to achieve equilibrium across a membrane or space.'
