Answer:
Explanation:
A correct Answer is an option: A) Palisade parenchyma.
Palisade is a layer of cells inside of the of leaves, comprising loosely oriented, irregularly shaped cells that possess chloroplasts.
The spongy parenchyma comprises a number of spaces between cells to facilitate the circulation of air with gasses and exchange themselves adequately.
