Most leaves have

Answer :

As the primary objective of leaves are to allow for photosynthesis so that the plant will have a source of food, the leaves will need to have a green pigment called chlorophyll as chlorophyll allows photosynthesis to take place as it converts light energy, in other words, sunlight, into chemical energy which is of use to the plant.


The upper part of the leaf is made up of palisade mesophyll cells which are tightly packed and have chloroplast in abundance.

The lower part of the leaf has spongy mesophyll cells which are not so tightly packed and have comparatively less chloroplast than palisade cells.

Chloroplast contains a green pigment called chlorophyll, due to which the leaves appear green.

Since the upper part of the leaf has cells that have chlorophyll in abundance, the upper part of the leaf appears darker.
