If future shoot hidden in a germinating seed is called plumule, then future root of the germinating seed would be ________.
cotyledon
sepal
petal
radicle
radicle
In a germinating seed, the plumule is the embryonic shoot that develops into the plant's stem and leaves. The radicle is the embryonic root that emerges first during germination to anchor the plant and begin absorbing water and minerals from the soil.
In a germinating seed, the plumule is the embryonic shoot that develops into the plant's stem and leaves. The radicle is the embryonic root that emerges first during germination to anchor the plant and begin absorbing water and minerals from the soil.
Think of the radicle as the 'anchor' that creates a foundation for the plant, while the plumule is the 'construction crew' that builds the leafy structure above ground.
During seed germination, the seed absorbs water (imbibition), causing the seed coat to rupture. The radicle is the first part to emerge, exhibiting positive geotropism to grow downward into the soil, followed by the plumule, which exhibits negative geotropism and grows upward toward sunlight to begin photosynthesis.
The radicle is the first part of a seedling (a growing plant embryo) to emerge from the seed during the process of germination.
The radicle grows downwards into the soil, forming the primary root system.
The plumule grows upwards, developing into the stem and leaves of the mature plant.

The radicle is essential for the survival of the seedling as it secures the plant in the soil and provides necessary nutrients.
Option A (cotyledon) refers to the embryonic seed leaf, Option B (sepal) is a floral leaf of a mature flower, and Option C (petal) is a floral part for attraction.
D is correct тАФ The future root of a germinating seed is known as the radicle, which is responsible for anchoring the plant and initial water absorption.
Remember: 'R' in Radicle stands for 'Root'. This mnemonic prevents confusion between plumule (shoot) and radicle (root) during exams.
