Here is all the labellings in the given picture below.
The epidermis covered with cuticle ( a waxy layer)
Abaxial lower surface have stoma ( atleast 1) .
Xylem is towards the adaxial surface (The xylem tissue is closest to the adaxial surface, because, when the vascular tissue bends over from the stem into the leaf, the xylem, which is closer to the center of the plant in each vascular bundle than the phloem)

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...

Exercise 3 Root Cross Section Examine the microscope slide containing the monocot and dicot root cross sections. Compare your cross section to the text diagram and the model. Find all the structures required. Draw and label each, side-by-side, so that visual comparisons can be made.

Examine the prepared slide, which is a cross-section of the
sponge Grantia. Look for incurrent canals, which allow
water to enter from the outside environment. Find the flagellated
canals that open to the spongocoel, the space
inside the sponge. Where would you expect to find choanocytes?
Sketch what you observe, labeling the key features. Draw an arrow
to show how water would move through the sponge.
