The middle stone age and the later stone age corresponds to the middle and the late pleistocene.
Cultural evolution during the middle and the late pleistocene :-
In southwestern Asia as well as northern and southern Africa, personal ornaments in the form of perforated seashells are recorded from the early Late Pleistocene. In the Old World, Neanderthals and anatomically modern humans are linked to a range of personal ornamentation by about 40,000 years ago (Ka). These include fully created ornaments as well as organically modified things. The appearance of figurative art, mythical imagery, and other types of items, like as musical instruments, at various times in history suggest that completely modern behavior began to emerge more gradually towards the middle of the Late Pleistocene and most definitely no later than 40 Ka. Many, but not all, of the lengthy and rigorous history of study might well have helped to the relevant data come from Europe.

Answer:
Palisade cells contain the largest number of chloroplasts per cell, which makes them the primary site of photosynthesis in the leaves of those plants that contain them, converting the energy in light to the chemical energy of carbohydrates
It tends to happen in capillaries
for example in the lungs avioli are coverd in capilarries so to facilitate the diffusion (exchange) of oxygen in to the blood stream and carbon dioxide out of the blood stream
