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 mesophyll cells are tightly packed, contain many chloroplasts, and are located near the upper leaf surface to maximize light absorption for photosynthesis. Spongy mesophyll cells have air spaces between them to facilitate gas exchange, allowing for efficient transport of gases needed for photosynthesis. The structural features of both cell types are adapted to their specific roles in photosynthesis - palisade mesophyll for light capture and spongy mesophyll for gas exchange.
The palisade mesophyll is located directly beneath, and then the spongy mesophyll is located beneath that. Both contain large amounts of chloroplasts which carry out photosynthesis.
A typical dorsiventral leaf has a petiole, leaf blade, mid rib and large number of veins. The leaf blade can be differentiated into palisade and spongy parenchyma. Both these tissues are surrounded by an epidermis which is interspersed by stomatal pores. The mid rib and its associated veins are provided with vascular bundles.
Bifacial leaves are leaves that have photosynthetic cells on both the upper and lower surfaces, allowing them to capture sunlight from both sides for increased efficiency. This adaptation is often seen in plants that grow in low-light environments or have a need to maximize their photosynthetic potential.
Their are two types of leaves- Iso-bilateral and dorsi-ventral. In isobilateral leaves mesophyll on both sides (dorsal & ventral) remain similar but in dorsiventral leaves it consists of columnar palisade cells on dorsal side and of spongy parenchyma on the ventral side. The spongy parenchyma contains lots of air spaces however in isobilateral leaves the mesophyll may or may not contain the air spaces.
A succulent and a cactus both store water in their spongy stem or leaves.

The palisade mesophyll is located directly beneath, and then the spongy mesophyll is located beneath that. Both contain large amounts of chloroplasts which carry out photosynthesis.
Because it contains air spaces which help regulate gas exchange in leaves and because most of the chloroplast are located in the palisade layer, it is here where the photosynthesis mainly takes place.
Both red and white blood cells are produced in the spongy bone marrow.
They are both shades of purple and blue

The fishhook barrel cactus is found in both the Chihuahuan Desert and the Sonoran Desert.
The plural forms for cactus are cacti or cactuses, both are accepted.
