Final answer:
The correct answer is Option 1: Growing Point; Primordia; Leaves. In leaf development, the growth point, or apical meristem, continuously forms leaf primordia, which eventually develop into fully expanded leaves.
Step-by-step explanation:
The correct answer is Option 1: Growing Point; Primordia; Leaves.
In leaf development, the process starts with the growth of a leaf primordium, which eventually develops into fully expanded leaves. The growth point, or apical meristem, continuously forms leaf primordia, and these primordia go on to form fully expanded leaves.
For example, in the case of dandelion, branch primordia are initially produced, but they are only activated to grow after being transformed into flower primordia. When activated, they produce a leaf-less dandelion 'flower'.
