Phloem: In vascular plants, phloem is the living tissue that carries organic nutrients (known as photosynthate), in particular, sucrose, a sugar, to all parts of the plant where needed.

Function: Transportation of food and nutrients from leaves to storage organs and growing parts of plant.

Xylem: is one of the two types of transport tissue in vascular plants (phloem is the other).

Function: Water and mineral transport from roots to aerial parts of the plant.

Protocol:

•          set the microscope
•          get the stem
•           cut horizontally a tiny slice
•          set on the slide the specimen
•          use 4x to watch the specimen
• ·              

Reactive:

•          water
•          oil (immense)
•          blue-methilem

Stomata: a stoma is a pore, found in the leaf and stem epidermis that is used for gaseous exchange. The pore is bordered by a pair of specialized [parenchyma] cells known as guard cells that are responsible for regulating the size of the opening.

Materials:

•         knife
•      pice of leaf
•          microscope
•          slide
•          container
