Plant Transportation

• Phloem transports food
• Xylem takes water up the plant and transports it to the leaves and other parts of the plant
• Osmosis is the movement of water molecules from a region of high water concentration to a region of low water concentration
• Active transport is the movement of molecules from an area of low concentration to an area of high concentration against a concentration gradient
• Transpiration is the loss of water vapour from the stomata of a plant
• Diffusion is the net movement of particles from an area of high concentration to an area of low concentration.
• Diffusion takes place in liquids and gases because the particles are able to move freely
• Diffusion happens because of the random movement of particles
• Independent variable - Something we change
• Dependent variable - What we measure
• Active transport requires energy from respiration to move substances against their concentration gradient.
• In soil, there is a low mineral concentration, so the mineral molecules require energy to move into the cell using lots of energy from respiration
