List three morphological characteristics used to identify woody shrubs.

List three morphological characteristics used to identify woody shrubs.

• A. Leaf arrangement (opposite vs. alternate), leaf margin (serration, lobing), twig characteristics (bud scales, lenticels) and bark texture
• B. Flower color, fruit size, scent, growth rate
• C. Root depth, drought tolerance, leaf thickness
• D. Seed type, leaf color, stem height

Answer: (A)

Identifying woody shrubs relies on observable physical features—morphology—that you can see on the plant itself. The most useful set includes how leaves are arranged on the stem (opposite vs. alternate), the edges of the leaves (serration or lobing), and specific twig traits such as bud scales and lenticels, along with the texture and appearance of the bark. Together, these characteristics are consistently visible across seasons and are commonly used in field guides to distinguish species.

Other traits shown in the options—flower color, fruit size, scent, and growth rate—depend a lot on the plant’s environment and season and aren’t as reliable for identifying shrubs when they aren’t flowering. Traits like root depth, drought tolerance, and leaf thickness are more about physiology or adaptation than a quick, field-identifiable look. Seed type, leaf color variability, and stem height can vary with age and conditions and aren’t as diagnostic as the visible combination of leaf arrangement, leaf margins, twig features, and bark texture.

So, focusing on leaf arrangement, leaf margin, twig characteristics, and bark texture gives the strongest, most practical set of morphological clues for identifying woody shrubs.
