In synthetic seed technology, preserved somatic embryoids (after encapsulation or storage) are commonly termed:

Introduction / Context:
Synthetic seed technology packages somatic embryos into bead-like units that mimic true seeds for handling, storage, and sowing. The terminology helps standardize communication between labs and nurseries.

Given Data / Assumptions:

• Somatic embryos are produced via tissue culture (not from fertilization).
• Encapsulation uses hydrogels such as sodium alginate–calcium chloride systems.
• Objective: seed-like handling and potential direct planting.

Concept / Approach:
Once embryoids are encapsulated or preserved for later use, they are referred to as synthetic seeds. The term emphasizes their functional analogy to zygotic seeds while acknowledging their somatic origin and artificial coating.

Step-by-Step Solution:

Verification / Alternative check:
Protocols across horticultural species use “synthetic seeds” to denote encapsulated somatic embryos; no equivalent natural seed coat is present.

Why Other Options Are Wrong:

• B: “Semi-synthetic” is not standard.
• C/D: Natural or fermented seeds do not describe tissue-culture-derived embryoids.
• E: Spores are different reproductive structures.

Common Pitfalls:
Confusing somatic embryos with zygotic embryos; the presence of a protective gel does not create a true seed coat.

Final Answer:
Synthetic seeds
