Rhoeo, including Rhoeo discolor andRhoeo spathacea, is a plant of many names. Depending on where you live, you may call this plant moses-in-the-cradle, moses-in-a-basket, boat lily and oyster plant.
Experiment:
Objective:
To prepare a temporary mount of a leaf peel to show stomata.
Apparatus and Materials Required:
A potted Tradescantia or Bryophyllum plant, forceps, needles, watch glasses, glass slides, a dropper, coverslips, a brush, blotting paper, safranin, glycerine and a compound microscope.
Theory:
Stomata are small openings found widely scattered on the epidermis of leaves and young stems. They are mostly found on the lower surface of a dicot leaf and on both the surfaces of a monocot leaf. Stomata regulate the exchange of gases and water vapour between the atmosphere and leaves.
Procedure:
1. Remove a healthy leaf from the potted plant.
2. Remove a part of the peel from the lower surface of the leaf. You can do this by folding the leaf over and gently pulling the peel apart using forceps. Keeps the peel in a watch glass containing water.
3. Put a few drops of safranin stain in a watch glass.
4. After 2-3 minutes take out the peel and place it on a clean glass slide.

The rheo plant's leaves are used in this experiment because the Rheo leaf has coloured cell sap,which can be examined clearly under a compound microscope.
