Root Explanation

**Nucellus** → It is derived from the Latin word "nucella" (meaning a small nut or kernel), which is a diminutive form of "nux" (meaning nut). The term refers to the small central part of a seed or ovule, often containing the embryo. Thus, "nucellus" signifies the small kernel or core within a seed.

Memory Tip

Think of a 'small nut' ('nucella') at the center of a seed, which helps you remember that 'nucellus' refers to the core part of a seed.
