translocation+transpiration

• sugar transport is translocatio
• water transport is transpiration
• plants make their own sugar through photosynthesis
• photosynthesis happens in the leaves
• photosynthesis happens in the leaves so the plant can make energy
• translocation is achieved through phloem cells
• phloem cells are arranged end on end to form phloem tubes
• phloem cells make phloem tubes
• inbetween phloem cells are pores
• the pores inbetween phloem cells enable movement of cell sap
• pores enable movement of cell sap
• cell sap is a liquid mix of water and sugar.
• pores allow the sugars from leaves to be transported long distance through multiple cells
• once sugar has been transported they can be used directly for energy or stored for later
• phloem can transport substances up and down the plant in andy direction
• next to phloem tubes are xylem tubes
• xylem cells are dead
• xylem cells have no ends between them forming one long hollow tube
• xylem cells form one long hollow tube
• xylem cells have no ends between them
• xylem tubes are strengthened with lignin
• xylem transport water and mineral ions from roots up stem to leaves
• xylem transports water and minerals from roots
• xylem transports water and mineral ions to leaves
• the water from roots can be used for photosynthesis
• translocation evaporates water from leaves of plant
• the transpiration stream drags water molecules up the plant once some water has been evaporated from the leaf
• what are the 4 factors that can effect transpiration?


  light intensity / temperature/ air flow/ humidity
• brighter the light means more photosynthesis
• more light intensity makes more stomata open up to let in carbon dioxide needed for photosynthesis
• light intensity means more water can evaporate
• light intesity causes a higher rate of transpiration
• once it turns night the stomata close meaning there's very little transpiration
• temperature makes transpiration rate higher because its warmer
• warmer highers rate of transpiration
• particles of water gain more energy causing them to evaporate
• warmer weather highers the rate of transpiraion
• the inside of a leaf has a higher concentration of water than outside
• air flow for example windy weather
• water molecules that leave the leaf are quickly going to be blown away on awindy day
