Answer Details

Plants that show secondary growth are usually found among the dicotyledons. Secondary growth refers to the increase in girth or thickness of a plant stem or root. It occurs due to the activity of lateral meristems, which produce new cells that differentiate into secondary tissues such as secondary xylem and phloem. These tissues provide mechanical support and conduct water and nutrients throughout the plant. Dicotyledons are a group of flowering plants that have two seed leaves (cotyledons) when they germinate. They typically have a taproot system and their stems show secondary growth, resulting in the formation of a woody stem. This is in contrast to monocotyledons, which have a fibrous root system and lack secondary growth in their stems. Therefore, based on these characteristics, it can be concluded that plants that show secondary growth are usually found among the dicotyledons.
