Class.. 10 practical class started with the study of stomata. Stomata are the openings found on the surface of leaf which help in gaseous exchange. More number of stomata are distributed on the lower surface of leaf compared to the upper surface to prevent excess transpiration. Each stomata has two bean shaped guard cells surrounded by numerous epidermal cells. The opening is called the stoma or stomata pore through which gaseous exchange takes place.

    That looks like lots of fun! What type of plant leaf were you looking at? Did you make the slide yourself? It can be tricky to get a nice leaf peel. You have made me want to look at a variety of leaves to see if their stomata and other leaf cells look similar! 🙂
