Exercise II Histology of the Leaf PART A. MESOMORPHİC LEAF: SYRINGA VULGARIS Examine a prepared slide containing a transverse section of a Syringa (lilac) or another mesomorphic leaf. At first, use the microscope's 10x objective, then switch to the 43x objective. With the 10x objective in place, note the variation in size and orientation of the veins (vascular bundles), which contain the two vascular (conducting) tissues, xylem and phloem. The centrally located largest vein is the midvein. The midvein and...

3. Now examine a prepared slide of a Psilotren stem cross Section Notice the epidermis with its well-developed cuticle. Stomata are present here as well. The cortex is relatively large and has three regions. Beneath the epidermis is a region of parenchyma cells that contain chloroplasts (chlorenchyma). Adjacent to the chloren- chyma is typically a zone of sclerenchyma cells that give the stem support. The innermost portion of the cortex consists of another region of parenchyma...

The figure shows the cross section of a wall made of three layers. The thicknesses of the layers are L_1, L_2 = 0.600 L_1, and L_3 = 0.200 L_1. The thermal conductivities are k_1, k_2 = 0.900 k_1, and k_3 = 0.620 k_1. The temperatures at the left and right sides of the wall are T_H = 24 degree C and T_C = -20 degree C, respectively. Thermal conduction is steady. (a) What is the temperature difference Delta T_2, across...

Draw the slide under 400X. Indicate the cell type, magnification, and estimate the cell size. 14. Elodea 1. Prepare a wet mount of an Elodea leaf (Anarcharis). You will use one glass slide and cover slip for this entire lab. After preparing each slide, remove the specimen and throw it into the trash. Wash the slide in the sink. Dry the slide with a paper towel very carefully and pat the cover slip dry so that the plastic does not...

The figure shows the cross section of a wall made of three layers. The thicknesses of the layers are L1, L2 0.600 L1, and L3 0.400 L1. The thermal conductivities are k1, k2 0.820 k1, and k3 0.660 k1. The temperatures at the left and right sides of the wall are TH = 30 °C and Tc =-10 °C, respectively. Thermal conduction is steady. (a) What is the temperature difference AT2 across layer 2 (between the left and right sides...

The micrographs in this document are from a cross-section of the small intestine. This image is part of the field of view using a 10X eyepiece and a 4X objective, providing a total magnification of 40X. The digital camera image here is approximately 2/3 of the visual field of view, giving an actual magnification of about 60X. What tissues are visible here? For a closer look, change the size of the...

Lab Instructor: Lab Section: R03 Use the information in Figure 2 (your graph) and Table 1 to answer the following questions. 1. Describe the function of the cuticle and stomata in terrestrial plants. (2 marks) The function of a cuticle in terrestrial plants is to control and minimize cellular transpiration as much as possible to conserve water in the cells. The function of a stomata in terrestrial plants is to allow a passage for gas exchange through the cuticle from...
