In this lesson, students will investigate leaves up close to look for the structures responsible for gas exchange. Objectives. In this activity, students will: observe the structures that make up the surface of a leaf. find the pores, called stomata, that let gasses in/out of a leaf.
Leaf Stomata Microscopy Lab. This lab is easy and yields satisfying results. Materials: Fresh leaves---different leaves have different patterns of stomata distribution. Use leaves from several different plants or trees can compare the differences you see. Compound microscope.
observe the structures that make up the surface of a leaf. find the pores, called stomata, that let gasses in/out of a leaf. explore the ways that plants gain mass.
To prepare a temporary mount of a peel of a leaf in order to display the stomata of the leaf. Stomata is a tiny pore where gas exchange takes place, located on the under-surface of leaves.
Learn how leaves get their colors with leaf experiments. Use a microscope to study photosynthesis, chloroplasts, chlorophyll, plant growth, and pigments.
1. Lay the leaf flat on the table, with the side that you want to examine under the micrscope print facing up. 2. Paint a thin layer of clear nail polish on the leaf. 3. Wait a few minutes, then gently test a corner of the nail polish to make sure it is completely dry. 4. If dry, take a small piece of tape and put it directly over the nail
How To View Stomata Under The Microscope. Viewing stomata is a fun one-day lab during your photosynthesis or plant unit. The first time I had students do this lab, I got out razor blades (I know) and tried to have students cut off thin slices of the leaf.
