Transporte en las Células: Difusión y Ósmosis

The video tutorial explores how substances move across cell membranes through diffusion, osmosis, and active transport. It explains diffusion as the movement of particles from high to low concentration, with examples like gas exchange in lungs and nutrient absorption in intestines. Osmosis, a similar process for water, is discussed, highlighting its effects on animal and plant cells. Specialized exchange surfaces in organisms, such as alveoli and root hairs, are also mentioned.

What role do specialized exchange surfaces play in the transport of substances?
