What is the mesohyll?

Answer 1

The mesohyl, formerly known as mesenchyme, is a gelatinous matrix within a sponge. The mesohyl resembles a type of connective tissue and contains several amoeboid cells, fibrils, and skeletal elements. For hundred of years, it has been largely accepted that sponges lack true tissue, but it is currently debated as to whether mesohyl and pinacoderm layers are in fact tissues

Answer 2

The mesophyll is a tissue found in plant leaves that is responsible for photosynthesis. It is divided into two layers: the palisade mesophyll, which is located closer to the upper epidermis and contains densely packed chloroplasts for light absorption, and the spongy mesophyll, which is located beneath the palisade layer and has air spaces for gas exchange.
