Answer:
Simple cuboidal epithelia are found in areas that stretch.
Explanation:
The simple cuboidal epithelium consists of a single layer of cuboid cells with a centrally located nucleus. The cells of this epithelial tissue are mostly involved in secretion and absorption and therefore, are found in the lining of ovaries, lining of kidney tubules and gland ducts.
Transitional epithelium is like a stratified cuboidal epithelium when not stretched. Its cells become flatter when the tissue is stretched. It has multiple cell layers and elasticity and therefore, is found in the lining of the urinary bladder and parts of ureter and urethra to allow stretching of these organs.
