How does the arrangement of cells in the palisade mesophyll help with photosynthesis?
The loosely packed cells provide space for gas exchange.
The cells are tightly packed with many chloroplasts to absorb more light.
The cells transport water quickly to the leaf.
The arrangement blocks excess light from reaching the leaf.

Explanation

The tightly packed arrangement maximizes light absorption.
