Read the given statements. Choose the correct set of code that represents two correct statements:
A. During embryogeny, suspensor is an ephemeral structure found at the radicular end of embryo-sac.
B. During grass-embryo development, a very large suspensor is formed.
C. Suspensor attains maximal size at globular/heart-shaped stage of embryo development in a dicot ovule/seed.
D. Suspensor does not plays an important nourishing role during initial stages of new seedling formation.

Correct option is D

Correct Answer: (d)
Explanation:
A — True. The suspensor is generally an ephemeral structure that originates at the micropylar/radicular end of the embryo sac and commonly degenerates as embryo develops.
B — True. In many grasses (some monocots) the suspensor is conspicuous and relatively large compared with that in many dicots.
C — Not universally true. While suspensors may be relatively large in very early stages, saying they attain maximal size specifically at the globular/heart stage for dicots is not a general rule across taxa — suspensor size and timing of degeneration vary.
D — Not true. Suspensor often aids in nutrient transfer in early embryogenesis.
Information Booster:
Suspensor pushes the embryo into nutritive tissue and often helps early nutrient transfer.
It is typically short-lived (ephemeral) and degenerates as the embryo matures.
In some plants (notably many monocots) the suspensor can be more prominent.
Modes of apomixis and embryogenesis show wide variation in suspensor formation and fate.
Terminology: micropylar end ≈ future radicle end in many descriptions.
