Tightly packed cells: forms a protective layer over a plant
transparent: lets light get to the tissues where photosynthesis happens
Waxy layer (the cuticle): reduces water loss
Palisade mesophyll tissue structure and function
Tightly packed with cells that contain lots of chloroplasts: where most photosynthesis happens in a leaf
Spongy mesophyll tissue structure and function
Loosely packed cells surrounded by air spaces: allow gases to diffuse in and out of cells for photosynthesis
Xylem structure and function
Made up of hollow tubes: transports water and mineral ions from a plant’s roots to its stem and leaves
strengthened with lignin: helps to support a plant
Phloem tissue structure and function
Made up of tubes of elongated cells with pores in their end walls: transports dissolved sugars from a plant’s leaves to the rest of the plant for use or storage
