the leaf Flashcards
what is the epidermal tissue
covers the entire plant and has a waxy cuticle that prevents water loss by evaporation
what is the stomata
small hole that allows carbon dioxide and oxyegen to exit the leaf
what are the guard cells
control the stomata and close when too much water is being lost or gained
what is spongy mesophyll
cells not packed closely together so carbon dioxide and and oxygen can diffuse through the leaf and reach cells
what is the palisade mesophyll tissue
upper layer of leaf where photosynthesis takes place
what is xylem
movement of water and mineral ions
what is phloem
movement of food substances
what is translocation
methods of which plants use to transport food molecules through the phloem and around the plant
what is transpiration
loss of water from a plant
