Plant tissues

• where are the air spaces within the plant?


  in the spongy mesophyll
• where is the epidermal tissues found?


  covers surface of the whole plant
• what are the main functions of the epidermal tissues?


  protection/ prevent water loss
• where is the palisade mesophyll found?


  in the upper layer of the leaf
• what are the main functions of the palisade mesophyll?


  photosynthesis
• where is the spongy mesophyll found?


  the lower layer of the leaf
• main functions of the spongy mesophyll?

  allow diffusion of CO2 through leaf for photosynthesis
• how to remember what xylem and phloem do?


  "ph" makes an f sound, so f for food, which is glucose
• what does phloem do?


  transport products of phtosynthesis. glucose + oxygen
• what does xylem do?


  transports water and minerals
• where is meristem tissue located?


  growing tips of roots and shoots between xylem and phloem
• what does the meristem tissue do?


  is able to differentiate into lots of different types of plant cell allowing the plant to grow.
• how do oxygen and co2 enter the plant?


  diffusion through stomata and air spaces
• How do root haair cells uptake water?

  by osmosis
• Where does the water enter the plant?


  through the roots
• what surrounds the guard cells?


  epidermis cells
• where is the meristem tissue of a plant found?

  growing tips of roots and shoots
