spongy layers
The tissues of a leaf are arranged in layers. Starting from the top, there is the upper epidermis, followed by the palisade mesophyll, spongy mesophyll, lower epidermis, and stomata. These layers work together to carry out photosynthesis, gas exchange, and structural support for the leaf.
Leaf cells are typically multicellular, forming layers of specialized cells in the leaf tissue. Each type of leaf cell plays a specific role in processes like photosynthesis, gas exchange, or structural support within the leaf structure.

The spongy mesophyll and pallisade mosophyl layers form the middle layers of the leaf. The pallisade mesophyl contains many tightly packed cells which do photosynthesis. The spongy mesophyl contains mainly hollow space, allowing for gas exchange.
Earth's compositional layers are the crust, mantle, and core, based on the materials they are made of (silicates vs. metals). Structural layers are based on their physical properties and include the lithosphere, asthenosphere, mesosphere, outer core, and inner core. The main difference is that compositional layers are defined by chemical differences, while structural layers are based on physical properties like temperature and behavior.
It is formed slat rock and covered up with layers and layers of rock and sediment.
It's the top of the leaf which has many layers

The top layer of concrete is called the structural coat. It directly receives the most load which must then be transferred to lower layers.
The portion of a leaf that wraps around the stem at the base of the blade on a grass plant is called the sheath. It helps to provide structural support to the leaf and connects it to the stem.
