Final answer:
A single layer of cube-like cells represents a simple cuboidal epithelium, which is involved in secretion and absorption and is found in glandular tissues as well as the kidney and liver.
Step-by-step explanation:
A single layer of cube-shaped cells with a central nucleus is known as a simple cuboidal epithelium. This type of epithelium is primarily involved in functions such as secretion and absorption. The cuboidal epithelial cells are most commonly found lining the ducts and tubules of glands, as well as the kidney and liver.
They form a simple epithelium since they are organized in a single layer, with each cell resting on the basal lamina, providing an efficient structure for the glandular functions they perform.
