What would be the advantages or having no chloroplast in the cell of the spongy mesophyll

The advantage of having no chloroplast in the cell of the spongy mesophyll is:

A chloroplast is an organ in the cell of a living plant which enables it absorb sunlight and convert it to oxygen and food.

As a result of this, when there is little chloroplast in the spongy mesophyll, then there will be a change in the function of the waxy cuticle which helps to prevent dehydration in the cell.

The main advantage of the absence of the chloroplasts in the spongy mesophyll is that, it can keep the water molecules, prevents it from dehydration inside the leaf cell by the help of its waxy cuticle.

Explanation:

Less chloroplasts are present in the spongy mesophyll as maximum chloroplast present in the palisade side absorbs the light energy. Keeping the water molecules inside the leaf cell through the waxy cuticle.  The waxy cuticle protects the cell from getting dehydrated or couldn't lose much moisture. The spongy mesophyll on the other hand helps in regulation of the products as well as the reactants. Inside the spongy mesophyll the chloroplasts are located far apart from the surface i.e. they should actually present.

several tissues working together form an organ, and several organs together make up an organisms.

the group of cell that carries out special jobs are tissue.
