Detailed explanation-1: -The thick an-like leaves, that have long palisade cells and the greater amount of chloroplasts per unit area, are clearly beneficial to plants that are always exposed to strong light, for example the climbing plants.

Detailed explanation-2: -There was a surprisingly large range of palisade cell diameter, even within a single piece of leaf, from approx. 27 to approx. 7 µm, and a corresponding range of cell number per standard field (approx. 20 to approx.

Detailed explanation-3: -The palisade parenchyma tissue usually is located on the upper side of the leaf, and the spongy parenchyma on the lower side. There may be only a single layer of palisade cells perpendicularly arranged below the upper epidermis, or there may be as many as three layers.
