Lesson: Active Transport Biology

Students will be able to

• define active transport as the movement of particles from an area of low concentration to an area of high concentration,
• define the term concentration gradient and understand that active transport moves particles against their concentration gradient,
• recall that active transport requires an input of energy,
• describe examples of active transport in organisms, including the movement of mineral ions from the soil into plant roots and the movement of glucose from the cells of the small intestines into the blood,
• compare and contrast the movement of particles by active transport and diffusion.
