Identify the wrong statement in the context of heartwood.

Options

  1. AOrganic compounds are deposited in it
  2. BIt is highly durable
  3. CIt conducts water and minerals efficiently
  4. DIt comprises dead elements with highly lignified walls

Correct answer

C. It conducts water and minerals efficiently

Step-by-step solution

Heartwood is physiologically inactive due to the deposition of organic compounds and tyloses formation, so this will not conduct water and minerals. Heartwood is the central cylinder found in tree trunks. Heartwood forms as the tree ages, and the inner xylem cells lose the capacity to transmit water. Heartwood tends to be darker in colour than sapwood since it is normally filled with various types of oils, dyes, and sugars. The primary function of heartwood is to provide adequate support to the tree.
