Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Loosely packed mesophyll cells, called ____, create air spaces that connect with the outside of the plant through stomata.
A
palisade mesophyll
B
upper epidermis
C
spongy mesophyll
D
cuticle
Explanation: 

Detailed explanation-1: -Spongy mesophyll tissue is packed loosely for efficient gas exchange. The spongy mesophyll cells are covered by a thin layer of water. Gases dissolve in this water as they move into and out of the cells.

Detailed explanation-2: -The cells in the spongy mesophyll layer are not as closely packed as the cells in the palisade mesophyll layer. This creates air spaces inside the leaf to enable gases to move in and out.
