Difficulty: Easy
Choose an option
-
ABoth internal hormones (auxins, gibberellins, cytokinins, ABA, ethylene) and environmental factors (light, temperature, gravity, water, nutrients)
-
BOnly temperature
-
COnly water availability
-
DOnly mineral nutrients
Answer
Correct Answer: Both internal hormones (auxins, gibberellins, cytokinins, ABA, ethylene) and environmental factors (light, temperature, gravity, water, nutrients)
Explanation
Given data & Concept
- Plant development depends on intrinsic signals (phytohormones such as auxin, GA, cytokinin, ABA, ethylene) and extrinsic cues (light/photoperiod, temperature/vernalization, gravity, water, nutrients).
ApproachSelecting the comprehensive option reflects the integrated regulation of growth, differentiation, and morphogenesis in plants.
Final AnswerBoth hormones and environmental factors influence plant development.
