You have been assigned the task of identifying the cells in a plant tissue sample.Using your microscope you determine the cells are living and their cell walls vary in thickness.Upon further observation you note that the cells are arranged in strands just below the epidermal surface.What cell type do you determine the cells to be?

The fact that the cells are living and their cell walls vary in thickness is characteristic of collenchyma cells. The arrangement of cells in strands just below the epidermal surface is also typical of collenchyma cells. Parenchyma cells typically have thin, flexible cell walls and are more loosely arranged, while sclerenchyma cells have thick, rigid cell walls and are typically found in regions of the plant that require support or protection. Sieve elements and tracheids are types of cells found in the phloem and xylem, respectively, and would not be expected in the epidermal layer.
