Key Questions:

1. How do the structures of each plant tissue relate to their function?
   • The epidermis tissue within a plant is thin and transparent in order to let light to reach the palisade layer. The palisade mesophyll tissue has many chloroplasts as it is the main site of photosynthesis. The spongy mesophyll tissue has large gaps to allow for gas exchange. The xylem is made of a column of dead Cells which are waterproof. Phloem is made of live Cells protected in the middle of the plant so they can transport glucose. The meristem tissue is made of stem Cells which allow for rapid growth and repair.
2. What tissues are found within the plant?
   • Plant tissues include: - epidermal tissues - palisade mesophyll - spongy mesophyll - xylem and phloem - meristem tissue found at the growing tips of shoots and roots.
3. What level of organisation do plant leaves fall into?
   • The leaf is a plant organ.
