BOTANY

Detailed explanation-1: -Vascular Tissue: The vascular tissue is actually found in the veins of the leaf. The vascular tissues are composed of xylem and phloem which are responsible for the transport of water and food.

Detailed explanation-2: -Veins are composed of xylem and phloem cells embedded in parenchyma, sometimes sclerenchyma, and surrounded by bundle sheath cells. The vein xylem transports water from the petiole throughout the lamina mesophyll, and the phloem transports sugars out of the leaf to the rest of the plant.

Detailed explanation-3: -Generally, leaf base, petiole, and lamina, together form the main parts of a leaf. Leaf Base: This is the part where a leaf attaches to the stem. Leaf base has two small leaf-like structure called stipules.

Detailed explanation-4: -The arrangement of the pattern of veins in a leaf is called venation.

Detailed explanation-5: -Three major venation patterns in simple leaves are “palmate”, “pinnate”, or “parallel” (Figure 17, left to right). Typically there is a prominent central vein (the midrib) running from the leaf base to its tip.
