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.

The spaces between leaf veins are called interveinal areas. These areas are usually filled with chloroplasts, which are responsible for photosynthesis. The arrangement of veins and interveinal areas in leaves is important for nutrient and water transport.
The air spaces in the spongy mesophyll connect with the exterior of the leaf through small pores called stomata. Stomata are located on the underside of the leaf and allow for gas exchange between the interior of the leaf and the surrounding environment.
The majority of a leaf is composed of mesophyll tissue, which contains two types: palisade mesophyll and spongy mesophyll. Palisade mesophyll is located near the upper surface of the leaf and is responsible for most of the photosynthesis, while spongy mesophyll is found below and aids in gas exchange and nutrient storage.

Leaves have spongy tissue to facilitate gas exchange and photosynthesis. This tissue, located in the mesophyll layer, contains loosely arranged cells with air spaces that allow carbon dioxide to diffuse into the leaf and oxygen to exit. Additionally, the spongy tissue helps in retaining moisture and provides structural support, ensuring the leaf can efficiently capture light and perform its vital functions.

Spongy tissue in leaves has loosely packed cells with large air spaces between them, facilitating gas exchange. In contrast, other leaf tissues like palisade mesophyll have tightly packed cells arranged in columns for efficient photosynthesis. Spongy tissue is located beneath the palisade layer and aids in maximizing gas diffusion within the leaf.
The cellular material inside a leaf is arranged with various spaces and gaps between the cells. These spaces allow for the movement of gases, such as carbon dioxide and oxygen, as well as water and nutrients throughout the leaf. This arrangement is crucial for photosynthesis and overall leaf function.
Intercellular air in leaves allows for gas exchange between the leaf cells and the atmosphere, facilitating photosynthesis and respiration. This also helps in maintaining optimal levels of oxygen and carbon dioxide within the leaf for metabolic processes. Additionally, intercellular air spaces provide structural support and buoyancy to the leaf tissue.
