The iris is an example of which plant category?

• A. Dicotyledon
• B. Monocotyledon
• C. Gymnosperm
• D. Angiosperm

Answer: (B)

Understanding monocots helps identify iris. Iris is a monocot because it shows the traits typical of monocots: a single seed leaf (cotyledon) in the seed, leaves with parallel veins, and flower parts in threes. In iris, the leaves are long and narrow with parallel veins, and the blossoms are arranged in groups of three petals and three sepals, which aligns with monocot patterns. These features contrast with dicotyledons, which usually have net-like leaf venation and flower parts in multiples of four or five, and with gymnosperms, which do not produce flowers at all. While iris is indeed an angiosperm (a flowering plant), the distinguishing characteristic that pins it down to this specific group is that it is a monocot. Therefore, the best classification is monocotyledon.
