Stomata Leaf Peel Count

To count the number of pore leaves Purpose: • Check the epidermal pores and leaf epidermis. · Find out which side has more reasons. Prediction: Since the maximum amount of sunlight can enter the leaves without clogging, we predict that the pores under the leaves (lower epidermis) are larger than the upper epidermis. In addition, a smaller number of pores increases the surface area, thereby increasing the area available for light irradiation.

The number of pores on the surface of the leaves varies greatly depending on the plant species. There is a tendency that the total amount of the epidermis under the leaf is larger than the upper surface. The average number of vents is about 300 per square millimeter of leaves. The minimum number found in Tradescantia leaves is 14 per square millimeter. The maximum number of holes per square millimeter above the spanish oak leaves. Ostomate needles and ostomy found on broad leaves of angiosperms

The photograph shows the percutaneous, sunken and shaded leaves of the sun and shadow, and the number of each pore. Transcutaneous sections of sunlight leaves indicated epidermal cells did not notice pores or veins. Shaded leaves have epidermis and veins. The cross section of the sun shows epidermis, small cuticle and some leafy meats. The shaded cross section shows epidermis, subcutaneous, epidermis and thick mesophyll. Each leaf has no pores in leaves or parietal lobes. The number of pores in sunrise was 109, 107, 98, 111, 106. The average number of vents was 106.2. The number of pores in the shaded leaves were 113, 97, 121, 108, and 114, respectively, the average was 111, the area of ​​the leaves was divided by the area of ​​400 times, and then the number was multiplied by the number of pores The proportion of the skin was determined by things. The ratio of the epidermis to the pore of the sun leaves is 0.283. The proportion of leaves with shade is 03

Collect the leaves, place a thin layer of manicure on the underside of the leaves and let it dry. Put a strip of tape on top of dry manicure and gently remove the leaves. Observe the impression obtained with a microscope and calculate the number of pores per square millimeter.

Apply a thick layer of varnish nail polish to the top of the leaves. Make sure the leaves are completely dry. After drying, bond a single Scotch tape to the nail polish and gently and carefully peel off. Put the leaf impression on a clean slide glass and peel off the extra tape. Mark the slide appropriately. Focus the image at 400x magnification and calculate the number of holes present. Please change the view and explain. Repeat the epidermis beneath the leaves. Please carefully measure the diameter of the field of view using ocular graduation. The field diameter (μm) was calculated using a calibration table. The radius is calculated by dividing the diameter by two. Calculate the area using an expression. A = πr ". We convert the answer to centimeters by dividing the answer by 104. Since we calculate the number of pores per square centimeter we use the following formula to calculate the density.
