Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
what is the major photosynthetic region of the leaf?
A
palasade mesophyll layer
B
spongy layer
C
guard cells
D
stomata
Explanation: 

Detailed explanation-1: -Abstract. Cells of the mesophyll make up the bulk of internal leaf tissue and are the major site of photosynthesis in a plant by virtue of containing large populations of chloroplast organelles.

Detailed explanation-2: -Cells in the mesophyll of the leaf have numerous chloroplasts. In leaves, cells in the mesophyll (the tissue between the upper and lower epidermis) are uniquely suited to carry out photosynthesis on a large scale. This is due to their high concentration of chloroplasts, which are the sites of photosynthesis.

Detailed explanation-3: -There are two types of mesophyll cells in the leaves namely palisade mesophyll and spongy mesophyll. Mesophyll cells are provided with a large number of chloroplast. Photosynthesis occurs in the chloroplast. Hence mesophyll cells of leaves are the principal centre of photosynthesis.

Detailed explanation-4: -The palisade mesophyll layer is where most of the photosynthesis occurs in the leaf. The palisade cells contain a lot of chloroplasts to help them perform this photosynthesis. The palisade cells are closely packed together to maximize light absorption.

Detailed explanation-5: -The palisade mesophyll layer is made up of closely-packed, elongated cells located just below the upper epidermis. They contain chloroplasts and carry out most of the photosynthesis.
