A leaf is a plant organ that is flat, thin and usually green in color. (ii) Leaf-blade is enriched with reticulate venation. MEMORY METER. Monocot and Dicot Leaf: Type # 1. The presence of pigment ‘chlorophyll’ makes the leaf green in color that helps to prepare food in plants through photosynthesis.Collectively, green … axil - the angle between the upper side of the stem and a leaf or petiole. They absorb sunlight energy to make food. It consists of the upper and lower epidermis, which are present on either side of the leaf. So, the correct answer is ‘Petiole’ Q2. The outermost layer of the leaf is the epidermis. Leaf base has two small leaf-like structure called stipules. Some leaves are attached to the plant stem by a petiole.

Each leaf typically has a leaf blade called the lamina, which is also the widest part of the leaf. epidermis, mesophyll, and vascular bundle. Botanists call the upper side the adaxial surface (or adaxis) and the lower side the abaxial surface (or abaxis). 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. Identifying characteristics of the internal structure of dorsiventral or dicot leaf: (i) It is green, compressed with a wide lamina. Structure of a Typical Leaf. % Progress . In petiolate leaves, the leaf stalk is long. Epidermis. The epidermis aids in the regulation of gas exchange. shows prominent ridges and grooves and reveals the following tissues: Epidermis: 1. Leaf Base: This is the part where a leaf attaches to the stem. 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 cv+ìcÏe V lìsaåe pvsophy//4— veins a-f-ffo¿s ! ADVERTISEMENTS: The following points highlight the top two types of monocot and dicot leafs. stem - (also called the axis) the main support of the plant. 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. leaf apex - the outer end of a leaf; the end that is opposite the petiole. Q1. Click Create Assignment to assign this modality to your LMS. The internal structure of a leaf: Leaves are very important structures. List the la ers of the leaf starting at the upper cuticle all the way to the lower cuticle. Leaf Structure and Function. Leaves that do not have a petiole and are directly attached to the plant stem are called sessile leaves. midrib - the central rib of a leaf - it is usually continuous with the petiole. It is … Answers: Petiole is the stalk of a leaf that attaches the blade to the stem. It is mostly found above the ground and remains attached to the stem. Two epidermal […] 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. (iii) Mesophyll tissue is present and is composed of palisade parenchyma and spongy parenchyma. Leaf Structure and Function. ( i ) it is the structure of a leaf outer end of a leaf stalk long.
