How many layers is the upper epidermis?

A cross section through the blade of a typical dicot leaf reveals 4 distinct tissue layers. Upper epidermis. This is a single layer of cells containing few or no chloroplasts.

What is the difference between upper epidermis and lower epidermis?

Does upper epidermis have stomata?

Stomata are present in the sporophyte generation of all land plant groups except liverworts. In plants with floating leaves, stomata may be found only on the upper epidermis and submerged leaves may lack stomata entirely. Most tree species have stomata only on the lower leaf surface.

Why are stomata in the lower epidermis?

The lower epidermis is located on the underside of leaves. Stomata are usually present on the lower epidermis. In order to minimize transpiration that occurs with gas exchange, most dicot plants have their stomata on the lower epidermis.

Why is palisade layer a tissue?

The palisade layer of plant leaves is an example of such a tissue. This is because the cells of the palisade layer perform the function of trapping light and using it for photosynthesis. The cells are closely packed and regularly arranged to achieve their function.

Why is this waxy layer necessary?

The waxy covering on plant leaves, young stems, and fruit is called the “cuticle”. The purpose of this covering is to help the plant retain water. In arid regions, that is very important. In wetter regions, the waxy coating may help prevent infection by disease organisms.

Which two products are made from photosynthesis?

Let’s look at the products of photosynthesis! During the process of photosynthesis plants break apart the reactants of carbon dioxide and water and recombine them to produce oxygen (O2) and a form of sugar called glucose (C6H12O6).
