Final answer:
Sample preparation for observing stomata in a plant cell involves obtaining a leaf, cutting it into sections, removing the waxy cuticle, staining the sections, and observing them under a microscope.
Step-by-step explanation:
Sample preparation for observing stomata in a plant cell involves several steps:
Obtain a leaf from a plant.
Cut the leaf into small sections using a sharp blade or scissors.
Place the leaf sections in a solution of alcohol or acetone to remove the waxy cuticle on the leaf surface.
Rinse the leaf sections with water to remove any traces of the solution.
Stain the leaf sections with a dye such as toluidine blue or iodine solution to make the stomata more visible.
Mount the stained leaf sections on a microscope slide and cover with a coverslip.
Place the slide under a microscope and observe the stomata.
This process allows for the visualization of stomata, which are openings on the surface of leaves that control the exchange of gases and transpiration in plants.
