Support, Use in Photosynthesis, Transport of Minerals 1 of 9 How does water support the structure of the plant? Vacuoles push against the cell walls keeping them turgid 2 of 9 How do plants uptake water? Areas of high water concentration to areas of low water concentration through a partially permeable membrane (Osmosis) 3 of 9 How do plants uptake mineral salts? From areas of low to high concentration (Active Transport). Requires energy which is released during respiration 4 of 9 What is significant about root hair cells? Increased surface area allows for more absorption 5 of 9 What are the functions of Phloem? Carry sugar from photosynthetic areas of plant to less photosynthetic areas 6 of 9 What is the sugar used for? Converted to starch for storage and in respiration 7 of 9 Name 2 functions of Xylem Support, Transport of Minerals, Transport of Water 8 of 9 What is the function of stomata? Open and close to regulate transpiration 9 of 9
