You are observing a type of connective tissue that contains a variety of cells in a watery matrix. Based on these observations, what category of connective tissue are you looking at

Ground substances

Explanation:

Ground substance is the background material within which all other connective tissues are embedded. In ordinary connective tissue, the ground substance consists mainly of * water * whose primary role is to * provide a route for communication and transport (by diffusion) between tissues*.

This water is stabilized by a complex of Glycosaminoglycans (GAGS), Proteoglycans and Glycoproteins, all of which comprise only a small fraction of the weight of ground substance.

Ground substance is found in all cavities and cleft between the fibres and cells of the connective tissues. It is soluble in most of the solvents used to prepare-histological sections and therefore not visible in ordinary sections.
