Please someone tell that how to stain a plants leaf to observe stomata yaar Sahi answer Dena plz |
| Answer» TION:Material RequiredA potted plant of Bryophyllum or TradescantiaNeedlesForcepsWatch glassDropperGlass slidesA brushCoverslipsBlotting paperSafraninCompound microscopeGlycerineProcedurePick a healthy leaf from the potted plantFold the leaf to gently pull the peel apart to separate a peeled section from the lower surface of the leaf. Use the forceps to perform this step. Allow the peel to remain in a watch glass holding water for some time.In the watch glass, stain the sample by adding some drops of safranin through a dropper.Take the peel out after 2-3 minutes. Set it on a clear glass slideAdd a drop of glycerin on the peel. Put a clear coverslip over it gently using a needle.Excess glycerin and stain can be REMOVED using blotting paperExamine the slide first under a low-power and then under a high-power magnification of a compound microscope.Diagram Stomata OPENING and closureObservationVisible epidermal cells. The cells in their outline are irregular with no intercellular spacesSmall openings, stomata are scattered through the epidermal cellsGuard cells are observed which have chloroplasts and nucleusGuard cells are observed having a THIN outer covering and a thick inner boundary(concave)Guard cells control the closing and opening of the stomata.ConclusionsEpidermal cells are found containing stomata on the lower surfaces of the leaf.PrecautionsAvoid folding the leaf too much. The peel should be snipped to a proper sizeThe peel should always be placed at the centre of the slide and the slides should be held from the sides.The peel should neither be overstrained nor under strainedA brush should be used to handle the peel, otherwise would damage cells.Glycerin should be used in order to prevent drying of the peelCoverslip NEEDS to be placed in such a way that air bubbles are avoidedBlotting paper can be used to remove excess stain | |
