Final answer:
The best slide for a lab technician to choose to show an example of permanent tissue is one that contains xylem tissue or phloem tissue, as they are mature, specialized tissues responsible for the transport of water, nutrients, and sugars within the plant.
Step-by-step explanation:
A lab technician is looking for a slide that shows an example of permanent tissue. The best choice would be either xylem tissue or phloem tissue, as both of these are examples of permanent tissues that are involved in the transport of substances within the plant. Meristem tissues, such as apical and lateral meristems, are regions of active cell division and are therefore not considered permanent tissues but rather growth tissues. In contrast, xylem and phloem, which are part of the vascular system, have cells that are mature and specialized for their functions; xylem for transporting water and nutrients, and phloem for transporting sugars.
Given the options presented, c) Xylem tissue and d) Phloem tissue are correct answers. Both serve essential functions: xylem conducts water and minerals from roots to other parts of the plant, whereas phloem distributes the sugars made during photosynthesis. Therefore, if a technician is preparing microscope slides and is particularly interested in showing transport tissues, they would likely present slides of xylem and phloem.
