Subject: Biology
Level: Key Stage 4
Resource type: Whiteboard presentation
Teaching type: Multimedia lesson

Description

At the end of this activity, students should be able to:
– discuss the structure of phloem and indicate its location in a plant
– name the organic compounds produced during photosynthesis and stored in plants
– describe the transport of organic compounds from the leaves to other plant organs
– name examples of storage organs in plants.

Diffusion is the spreading of the particles of a gas, or of any substance in solution, resulting in a net movement from a region where they are of a higher concentration. Oxygen required for respiration passes through cell membranes by diffusion. Water often moves across boundaries by osmosis. Osmosis is the diffusion of water from a dilute to a more concentrated solution through a partially permeable membrane that allows the passage of water molecules. AQA GCSE Biology (4411) III.Biology 2 2. How do dissolved substances get into and out of cells? Dissolved substances can move into and out of cells by diffusion and osmosis. Water often moves across boundaries by osmosis. Osmosis is the diffusion of water from a dilute to a more concentrated solution through a partially permeable membrane that allows the passage of water molecules. III.Biology 3 1. How do dissolved materials get into and out of animals and plants? The surface area of the roots is increased by root hairs and the surface area of leaves by the flattened shape and internal air spaces. Plants lose water vapour from the surface of their leaves (transpiration). Most of the transpiration is through stomata. If plants lose water faster than it is replaced by the roots, the stomata can close to prevent wilting.
