Question

What are veins and veinlets of a leaf ?​

Answer 1

Explanation:

Veins, which support the lamina and transport materials to and from the leaf tissues, radiate through the lamina from the petiole. The types of venation are characteristic of different kinds of plants: for example, dicotyledons have netlike venation and usually free vein endings; monocotyledos.

veinlet is a small or secondary vein, especially on the wing of an insect while vein is (anatomy) a blood vessel that transports blood from the capillaries back to the heart.

Answer 2

$\mathfrak \purple{Veins}$

• 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.
