Which type of tissue is made up of phellem cells along with other specialized cells?

The type of tissue that includes phellem cells, often referred to as cork cells, is specifically known as cork or phellem tissue, typically categorized under a broader classification of protective tissues. This type of tissue serves a vital role in protecting plant structures and preventing water loss.

Meristematic tissue consists of undifferentiated cells capable of division, playing a crucial role in plant growth. Parenchyma tissue is a fundamental type of plant tissue involved in various functions, such as storage and photosynthesis, but does not include phellem cells. Vascular tissue consists of xylem and phloem, responsible for the transport of water, nutrients, and sugars throughout the plant.

The term "Meritism" appears to be a typographical error or non-standard term as it does not correspond to any recognized category of plant tissues. Therefore, the context of phellem cells specifically points to a tissue type that is distinct from those listed in the other options.
