Thorns are best described as which of the following?

• A. Modified Leaves
• B. Woody, Straight, Pointed Structures
• C. Modified Roots
• D. Modified Flowers

Answer: (B)

Thorns are best understood as sharp, defensive plant organs that are typically modified stems. They are usually woody and rigid, giving them a straight, pointed form that can resist being bent or broken. This makes sense because many thorns develop from the plant’s stems and become lignified, helping protect the plant from herbivores. It’s helpful to distinguish them from related structures: spines are modified leaves or leaf parts (not stems), while prickles are outgrowths from the epidermis rather than true stem modifications. So the description “woody, straight, pointed structures” captures the essence of thorns as sturdy, stem-derived defenses.
