Question

What is the difference between Veins and Lamina in plants?​

Answer 1

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. ... The arrangement of veins in a leaf is called the venation pattern. Monocots and dicots differ in their patterns of venation.

Answer 2

Answer:

Veins:

• 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.

Lamina:

• Lamina consists of a central tissue, called the mesophyll, surrounded on either side by upper and lower epidermis.
• Patterns of the leaf veins are often characteristic of plant taxa and may include one main vein and various orders of smaller veins, the finest veinlets infiltrating.
• Lamina is also called as Leaf blade
