Which of the following is NOT a type of tissue found in plants?

In plant biology, tissues are categorized based on their functions and characteristics. Dermal tissue serves as a protective outer layer for plants, guarding against physical damage and water loss. Vascular tissue is essential for the transport of water, nutrients, and food throughout the plant, with xylem and phloem serving as primary components. Ground tissue encompasses various types of cells that provide support, storage, and photosynthesis functions.

The term "non-living" does not fit into the categorization of plant tissues because all recognized plant tissues—dermal, vascular, and ground—are composed of living cells or can contain living cells at certain stages. While some components (such as the dead cells found in vascular tissue, like xylem) may serve a supportive or conducting role, the classification itself focuses on tissue types rather than on their living or non-living status. Thus, "non-living" does not represent a distinct type of tissue in plants.
