The function of the cork cambium is to produce

The cork cambium produces cork and phelloderm.

Explanation:

Cells' structural components decide their function. Cells arrange themselves into tissues, where specialized cell types carry out their functions in tandem. As cells mature, their function may even change over time, as they undergo certain subcellular changes in protein expression and signaling.

In larger plants, rigid tissues are needed to help support their modified stems, and transport water, minerals, other nutrients and food to different regions. Cork cambium is an unspecialized tissue found in the outermost plant layers. These act as meristematic regions; here, new tissues arise, growing outwards- these include:

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a
