There are 4 layers to the typical leaf; the upper epidermis, palisade layer, spongy layer and lower epidermis. ref http://users.rcn.com/jkimball.ma.ultranet/Biology/Pages/L/Leaf.html
The spongy layer is located beneath the upper epidermis in the mesophyll tissue of plant leaves. It is made up of loosely packed cells with air spaces between them, allowing for gas exchange and photosynthesis to occur more efficiently.
No, cacti do not have a spongy and palisade layer in their leaves like pine trees do. Cacti have specialized structures called spines and glochids instead of leaves, which help reduce water loss in arid environments. Pine leaves have a spongy layer that helps with gas exchange and a palisade layer for photosynthesis.
Palisade cells, spongy mesophyll cells, and guard cells contain chloroplasts in leaves. Palisade cells are located in the upper leaf epidermis, spongy mesophyll cells are below the palisade layer, and guard cells surround the stomata.
The layer of bone tissue you are referring to is spongy bone. It is made up of trabeculae, which are spiky structures that create open spaces filled with bone marrow. Spongy bone is important for providing structural support and flexibility to bones.

Yes
The spongy layer in a plant leaf facilitate better gaseous exchange for photosynthesis and respiration.
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 palisade layer and the spongy layer.
Aquifer?
Spongy Layer - A layer of the mesophyll. The spongy layer consists of chloroplasts and parenchyma cells, and relatively large intercellular spaces. It is far less ordered than the palisade layer, and the intercellular spaces are important in gas exchange and transpiration.
Spongy Layer
The spongy layer in plant leaves helps with gas exchange, allowing for the exchange of carbon dioxide and oxygen during photosynthesis.
Cacti lack a spongy layer in their stems because they have adapted to hot, dry environments with limited water availability. The absence of a spongy layer reduces the surface area for water loss through transpiration, helping cacti conserve water and survive in arid conditions.
The spongy bone which is the soft inner layer that has little holes and looks like a spongy hence the term spongy bone then the outer layer that everyone sees is the compact bone but the spongy bone is the most important because it cushions the bones when it gets squished and then it wont break
Spongy inner layer called cancellous bone. Spongy bone is lighter and less dense than compact bone
