According to GeeksforGeeks, plants absorb essential mineral elements from the soil through their roots, utilizing both active and passive transport mechanisms. Active absorption of nutrients is a fundamental biological process where organisms expend metabolic energy to take up substances, ensuring vital nutrients are acquired even when scarce.

Vitamin C absorption is a multi-layered process, and studies show that the body's efficiency at absorbing it declines significantly at doses over 1 gram. To fully answer the question of whether vitamin C uses facilitated diffusion, it is crucial to understand that its two forms, reduced ascorbic acid and oxidized dehydroascorbic acid, use different transport methods to enter cells.
