Which of the following is a list of parts included in the stem tissue?

The correct answer, which identifies the components of stem tissue as epidermis, cortex, xylem, phloem, and cambium, is accurate because these parts are fundamental to the structure and function of plant stems.

The epidermis is the outer layer that protects the stem and regulates gas exchange. The cortex, located beneath the epidermis, serves as a storage area and contributes to the transport of nutrients. Xylem is critical for transporting water and minerals from the roots to other parts of the plant, while phloem carries organic nutrients, particularly sugars, produced through photosynthesis. Cambium is a layer of actively dividing cells that contributes to secondary growth, allowing the plant to increase in diameter over time.

Each of these structures plays a vital role in the overall health and efficiency of a plant's vascular system, which is essential for its growth and development. The other options include terms that either do not pertain directly to the stem tissue structure or mix terminology from different plant components rather than providing a list of specific parts of the stem itself.
