Anatomy of Dicot Leaf. Anatomy of Monocot Leaf 2. epidermis, mesophyll, and vascular bundle. Blade – the main collecting structure of the leaf; Has a large, broad surface Has many layers which help the plant move and store photosynthetic materials and by - products Q1. The stalk of leaf is called A. Sessile B. Plumule C. Stipule D. Petiole. Some leaves are attached to the plant stem by a petiole. It is the structure through which products of photosynthesis are moved from leaves to the entire plant. Botanists call the upper side the adaxial surface (or adaxis) and the lower side the abaxial surface (or abaxis). The presence of pigment ‘chlorophyll’ makes the leaf green in color that helps to prepare food in plants through photosynthesis.Collectively, green … (iii) Mesophyll tissue is present and is composed of palisade parenchyma and spongy parenchyma. Anatomy of Monocot Leaf: Triticum-Leaf: ADVERTISEMENTS: T.S. The internal structure of a leaf: Leaves are very important structures. Identifying characteristics of the internal structure of dorsiventral or dicot leaf: (i) It is green, compressed with a wide lamina. Leaves that do not have a petiole and are directly attached to the plant stem are called sessile leaves. Leaf Structure and Function. Model 2 — Cross Section of the Internal Structure of a Leaf Cuticle Upper epidermis Chloroplast palisade mesophyll Air Space Lower epidermis Vein Spongy mesophyll Cuticle Guard cell f Stoma 8. Click Create Assignment to assign this modality to your LMS. ADVERTISEMENTS: The following points highlight the top two types of monocot and dicot leafs. The upper layer of a leaf is called the upper epidermis. Two epidermal […] Leaf Base: This is the part where a leaf attaches to the stem. It is mostly found above the ground and remains attached to the stem. : petiole - a leaf stalk; it attaches the leaf to the plant. Describes how leaves are made of several different kinds of specialized tissues. lamina - the blade of a leaf. List the la ers of the leaf starting at the upper cuticle all the way to the lower cuticle. The structure of a leaf is described below in detail : Parts of a Leaf. midrib - the central rib of a leaf - it is usually continuous with the petiole. The types are: 1. A leaf is a plant organ that is flat, thin and usually green in color. MEMORY METER. It is … Each leaf typically has a leaf blade called the lamina, which is also the widest part of the leaf. % Progress . It consists of the upper and lower epidermis, which are present on either side of the leaf. Leaf Structure and Function. Under a powerful microscope, we can see three main internal parts of a leaf, i.e. The internal structure of cacti stems conforms to the pattern of broad-leaved angiosperms; a cambium layer of dividing cells, located between the woody inner tissues and those near the outside of the stem, is present. shows prominent ridges and grooves and reveals the following tissues: Epidermis: 1. Describes the structure and function of leaves. Leaf base has two small leaf-like structure called stipules. leaf apex - the outer end of a leaf; the end that is opposite the petiole. Generally, leaf base, petiole, and lamina, together form the main parts of a leaf. stem - (also called the axis) the main support of the plant. Answers: Petiole is the stalk of a leaf that attaches the blade to the stem. So, the correct answer is ‘Petiole’ Q2. Petiole – is known as the leaf stem; It is not exactly like a stem, but it does hold xylem & phloem; Holds the blade away from the stem 7. (ii) Leaf-blade is enriched with reticulate venation. The outermost layer of the leaf is the epidermis. The epidermis aids in the regulation of gas exchange.
