Observe a prepared slide of a hydrophyte, such as Nymphaea, commonly called a water lily. Note the thin epidermal layer and the absence of stomata in the lower epidermis. In the spongy mesophyll, there are large pockets where air can be trapped.

Parts of a Leaf Diagram 1. Petiole It is the stalk that connects a leaf to the stem of the plant, it is made of complex conducting tissues called vascular tissues. Functions Providing support to the leaf and keeps it erect Transporting water and nutrients absorbed by the roots to the leaves Read the plant definitions below, then label the simple leaf morphology diagram below. axil - the angle between the upper side of the stem and a leaf or petiole. lamina - the blade of a leaf. leaf apex - the outer end of a leaf; the end that is opposite the petiole. midrib - the central rib of a leaf - it is usually continuous with the petiole.

The air space found between the spongy parenchyma cells allows gaseous exchange between the leaf and the outside atmosphere through the stomata. In aquatic plants, the intercellular spaces in the spongy parenchyma help the leaf float. Both layers of the mesophyll contain many chloroplasts. Figure 30.10. 1: Mesophyll: (a) (top) The central.

A leaf is a highly organized factory - an organ constructed of several kinds of specialized tissues, each of which has its own duties. The leaf blade is composed of tissue layers, each having an important part to play in a functioning leaf. Find these structures on the attached diagram of cellular leaf tissues.

Many leaves consist of a stalk-like petiole and a wide, flat blade (lamina). The midrib extends from the petiole to the leaf tip and contains the main vein. Each leaf typically has a leaf blade called the lamina, which is also the widest part of the leaf.Some leaves are attached to the plant stem by a petiole.Leaves that do not have a petiole and are directly attached to the plant stem are called sessile leaves. Small green appendages usually found at the base of the petiole are known as stipules.Most leaves have a midrib, which travels the length.
