Lesson: Absorbing Minerals Biology • Second Year of Secondary School

Students will be able to

• state that the essential nutrients of plants can be divided into macronutrients and micronutrients, with examples of each,
• state the roles of some macronutrients and micronutrients in plants,
• describe the process of diffusion as a mechanism of mineral absorption,
• describe how membranes of plant cells are partially permeable or semipermeable to allow the transport of particular minerals,
• describe active transport as a mechanism of mineral absorption,
• describe experiments carried out on Nitella algae to demonstrate the absorption of minerals,
• suggest what may happen to plants that do not obtain enough minerals.
