Leaves consist mostly of tissue called mesophyll, which is made up of loosely arranged cells with spaces between them. The spaces are filled with air, from which the cells absorb carbon dioxide and into which they expel oxygen.
Lying just beneath the cuticle layer on a leaf, the palisade layer resides very close to the surface. The palisade layer is critical to growth because it is the layer of the leaf that contains the chloroplast.
The spongy layer or mesophyll has many air spaces.
The spongy layer of a leaf, which lies beneath the palisade layer, consists of cells that are irregular in shape and loosely packed. Their main function seems to be the temporary storage of the sugars and amino acids that were synthesized in the palisade layer. The spongy layer also aids in the exchange of gases between the leaf and the environment.
The region in the leaf that has air spaces to facilitate the movement of gasses is the mesophyll region. This region is composed of layers of cells.
The troposphere is the layer of the atmosphere that contains people and weather. The troposphere is the only layer of the atmosphere that contains breathable air.
the spongy layer has alot of air spaces so gases can diffuse in and out of the leaf easily

Beneath the palisade layer of a leaf is the spongy mesophyll layer. This layer contains loosely packed cells with air spaces between them that allow for gas exchange, such as the intake of carbon dioxide and the release of oxygen during photosynthesis.
The air spaces in the mesophyll layer of a leaf help facilitate photosynthesis by allowing for the exchange of gases, such as carbon dioxide and oxygen. This enables the leaf to take in carbon dioxide needed for photosynthesis and release oxygen as a byproduct. The air spaces also help regulate the movement of water vapor, maintaining the proper balance of gases within the leaf for efficient photosynthesis to occur.
A layer underground that is impermeable and contains no void spaces for water or air is known as an impermeable layer or aquitard. This layer restricts the flow of water or gases through it due to its low permeability.

It contains air spaces (aerenchyma) within the cells of the petiole
There are large spaces in a leaf because it is for storing water and carbon dioxide which will be used for photosynthesis. The large air spaces are usually found in the spongy layer of the mesophyll.
Air spaces in the spongy layer of a leaf facilitate gas exchange by allowing for the movement of oxygen and carbon dioxide between the leaf cells and the external environment. This helps in photosynthesis by providing a pathway for carbon dioxide to reach the chloroplasts and for oxygen to exit the leaf during respiration.
Gas exchange
The layer underground where there are no empty spaces for water or air is known as the impermeable layer. This layer prevents the movement of fluids such as water or air because it is tightly compacted and does not allow permeation.
