Take a plant stem and with the help of your teacher cut into very thin slices or sections.
Now, stain the slices with safranin. Place one neatly cut section on a slide, and put a drop of glycerine.
Cover with a cover-slip and observe under a microscope. Observe the various types of cells and their arrangement.
Answer the following on the basis of your observations:
(a) Are all cells similar in structure?
(b) How many types of cells can be seen?
(c) Can we think of reasons why there would be so many types of cells?
(a) No, all cells are not similar in structure, we see variety of cells with different shape and size.
(b) We can see at least ten different types of cells in the slide.
(c) Yes, there are variety of cells so that each group of cell does a specific role in the overall growth of plant.
