Q. Arrangement of leaves in a plant is called as ____: Answer:
Phyllotaxy
Notes: The pattern of arrangement of leaves on the stem is called Phyllotaxy. As a stem grows at its apex, new leaf buds form along the stem by a highly controlled developmental process. Leaf arrangement along the plant stem depends on the species and is an important identifying characteristic. There are four basic types of phyllotaxy: alternate, spiral, opposite and whorled.
