A stem with a large pith region that typically lives 1-2 years is called what?

• A. Twig
• B. Branch
• C. Cane
• D. Shoot

Answer: (C)

When evaluating stems of perennial plants, a cane refers to a long, slender stem that is typically one to two years old and remains flexible rather than becoming permanent wood. The central portion, or pith, is relatively large, giving the stem a soft, light feel compared with woody branches. These canes aren’t long-lived permanent wood; after about one to two years they die back or are replaced by new growth from the base or from a rhizome. This distinguishes a cane from a twig, which is a smaller, younger shoot, and from a branch, which is a larger, more durable limb. A shoot is a general term for new growth, but the described stem fits cane due to its size, pith, and typical lifespan.
