Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What tissue contains cells where the majority of photosynthesis takes place?
A
spongy mesophyll
B
palisade mesophyll
C
upper epidermis
D
guard cells
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -Palisade cells are column-shaped, forming one part of the mesophyll layer along with the spongy mesophyll. The function of the palisade layer, which is also called the palisade mesophyll, is photosynthesis because it contains most of the chloroplasts in the leaf which maximize energy production during photosynthesis.

Detailed explanation-3: -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-4: -In plants, the process of photosynthesis takes place in the mesophyll of the leaves, inside the chloroplasts. Chloroplasts contain disc-shaped structures called thylakoids, which contain the pigment chlorophyll. Chlorophyll absorbs certain portions of the visible spectrum and captures energy from sunlight.
