They move from a high con to a low con. 3 of 12 Osmosis Transferring fluid between molecules. It's the movement of water from a less con to more con solution. 4 of 12 Solute The substance that dissolves in a liquid to form a solution. 5 of 12 Active transport The movement of ions/molecules across a cell membrane into a region of high con assisted by enzymes and they require energy. 6 of 12 Partially Permeable A membrane that allows small particles such as water molecules through it, but no larger particles such as sugar/glucose and ions from salts 7 of 12 Semi Permeable It will only allow certain molecules or ions to pass through it by diffusion or active transport. 8 of 12 biomass The total mass in living organisms, usually shown as the mass after drying 9 of 12 Cellulose Plant cell walls are made of tough cellulose, which support the cell and allow it to keep its shape. 10 of 12 Chlorpolast A green disc containing chlorophyll, found in plant cells. This is where the plant makes glucose through photosynthesis. 11 of 12 Food chain A diagram that uses arrows to show the flow of energy through organisms that depend on each other for food. 12 of 12
