By learning how to recognize parallel, pinnate, palmate, and other vein patterns you gain access to powerful tools for identifying plants even outside flowering seasons. The epidermis, mesophyll (modified parenchyma cells that conduct photosynthesis), and vascular bundles (veins) You'll learn how to remove leaf tissue so that their veins show.
I found a leaf that is half veins-only. : mildlyinteresting
The leaf veins are small channels or capillaries that transport water and minerals to and from the leaf of a plant
They are vascular tissues composed of xylem and phloem cells embedded mainly in the parenchyma and sometimes sclerenchyma cells
The outer layer of veins is made of bundle sheath cells. In the classical concept of a microphyll, the leaf vein emerges from the protostele without leaving a leaf gap Leaf gaps are small areas above the node of some leaves where there is no vascular tissue, as it has all been diverted to the leaf Megaphylls, in contrast, have multiple veins within the leaf and leaf gaps above them in the stem.
There are three main tissue types in the leaf
