Definition

Noun: 1. The rounded seed capsule of certain plants, especially cotton or flax: A boll is the rounded, protective, seed-bearing fruit or pod of specific plants, most notably the cotton plant.

  • Farmers monitor the bolls closely to determine the optimal harvest time. (Farmers watch the seed capsules to decide the best time for picking.)
  • A single cotton boll contains many seeds surrounded by lint. (One cotton pod holds numerous seeds covered in the raw cotton fibers.)
