Which of the following tissues is not found in the stem and root of monocotyledons?
Answer Details
Cambium is not found in the stem and root of monocotyledons.
Cambium is a type of tissue found in the stems and roots of dicotyledonous plants, which are plants with two cotyledons or seed leaves. Cambium is responsible for the growth in diameter of the plant stem or root, which allows for the formation of new xylem and phloem tissues.
In contrast, monocotyledonous plants, which are plants with only one cotyledon or seed leaf, do not have cambium tissue in their stems and roots. Instead, monocots have a different type of tissue called a ground tissue, which includes the pith and cortex. The pith is the central portion of the stem, while the cortex is the outer layer of the stem.
Monocots also have a type of tissue called the pericycle, which is responsible for the formation of lateral roots. The xylem tissue, which is responsible for transporting water and nutrients from the roots to the rest of the plant, is also found in the stems and roots of monocots, but it is arranged differently than in dicots. The xylem tissue in monocots is scattered throughout the stem or root, rather than forming a distinct ring as it does in dicots.
