What shape do Mimosa leaves
take? (A) Rosette, (B) deltoid, (C)
circular, (D) trifoliate, or (E) pinnate.
This question is asking us to
determine the shape of the leaves of the Mimosa plant.
The leaves of the Mimosa
plant are called compound leaves. This means that each leaf is made
of several distinct leaflets, which is the name given to the smaller leafy
subdivisions of the leaf. The stalk of the leaf is called the
petiole. The petiole branches into four
slender extensions called rachises. The multiple small leaflike
structures attached to each rachis are called pinnules or sometimes leaflets. Each rachis along with its pinnules
compose a single pinna. The pinnae give the shape of the
leaf its name: a pinnately compound leaf.
So the correct answer is (E). Mimosa leaves take a pinnate
shape.
