Plant growth is irreversible and results from cell division and enlargement. Primary growth increases length, while secondary growth increases thickness and is common in dicots, not monocots.

Arithmetic growth results in a linear curve, as one daughter cell divides while the other differentiates.

Auxin inhibits the growth of lateral buds, maintaining apical dominance.

Differentiation results in specialized cells with specific functions. Dedifferentiation allows some cells to regain division capacity, but xylem vessels cannot dedifferentiate.

Plasticity is the ability of a plant to produce different structures from the same meristem depending on environmental or developmental conditions.

Reduced trichomes (C) is correct here. This is core Phytohormone ALL: once you know the definition or pathway step, Reduced trichomes is the clear fit. The wrong ones are A) Increased trichomes; B) Normal trichomes; D) Larger leaves. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.

Binding PIFs and blocking transcription (B) is correct here. This is core Phytohormone ALL: once you know the definition or pathway step, Binding PIFs and blocking transcription is the clear fit. The wrong ones are A) Activating PIFs; C) Enhancing GA biosynthesis; D) Activating COP1. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.

B fits best: Downstream of GL1–GL3–TTG1. Keep the Jasmonic acid basics straight and Downstream of GL1–GL3–TTG1 stands out as the precise answer. Avoid: A) Upstream of GL1; C) As JA receptor; D) As JAZ protein. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.

Arabidopsis (C) is correct here. This is core Jasmonic acid: once you know the definition or pathway step, Arabidopsis is the clear fit. The wrong ones are A) Rice; B) Maize; D) Wheat. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.

B fits best: Dark. Keep the Brassinosteriod basics straight and Dark stands out as the precise answer. Avoid: A) Light; C) UV; D) Red light. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.
