Understanding the Analogy: Seed to Sapling

The question presents a word analogy based on a developmental relationship. The first pair is 'Seed: Sapling'.

A Seed is the initial stage from which a new plant begins to grow. A Sapling is a young tree, representing an early stage of growth that develops directly from a seed.

The relationship can be defined as: 'An early stage of development' develops into 'a later, young stage of development'.

Applying the Analogy: Fetus to the Next Stage

The second part of the analogy involves 'Fetus'. We need to find a word from the options that represents the stage following the 'Fetus' stage, similar to how 'Sapling' follows 'Seed'.

Let's analyze the options in the context of human (or animal) development:

• Fetus: This is a stage in prenatal development, typically from the ninth week after conception until birth. It follows the embryonic stage and is characterized by the development of major organs and body systems.
• Embryo: This is an earlier stage of development, generally referring to the period from conception up to about the eighth week of pregnancy. The Fetus develops from the Embryo.
• Infant: This term refers to a very young human child, typically from birth up to one year of age. The transition from Fetus to Infant occurs at birth.
• Child: This refers to a broader age range, usually from infancy up to puberty or the legal age of majority.
• Adult: This refers to a fully grown, mature person.

Identifying the Correct Relationship

Comparing the relationships:

• Seed → Sapling (Plant development: initial stage → young stage)
• Fetus → ? (Human/Animal development: late prenatal stage → early postnatal stage)

The Fetus is the stage just before birth. The stage immediately following birth is the Infant stage.

Therefore, the relationship between Fetus and Infant is analogous to the relationship between Seed and Sapling, representing a progression from an early developmental phase to a subsequent young phase.

The correct answer is the term representing the stage immediately after the fetal stage.

Conclusion

The progression from Seed to Sapling mirrors the progression from Fetus to Infant. Both represent a transition from a developing organism to a young, newly formed individual.
