Match each plant growth feature or developmental phenomenon on the left with its correct biological description on the right.
- Apical meristemTissue responsible for primary growth and extension in length at root and shoot tips
- Hypogeal germinationGermination type where cotyledons remain below the soil surface due to epicotyl elongation
- EcdysisPeriodic shedding of the chitinous exoskeleton to enable increase in body size
- Sigmoid growth curveGrowth pattern comprising lag, exponential, decelerating, and stationary phases
Cevap
Apical meristem matches with tissue responsible for primary growth at root and shoot tips; Hypogeal germination matches with germination where cotyledons remain below soil level; Ecdysis matches with periodic shedding of exoskeleton; Sigmoid growth curve matches with S-shaped growth pattern consisting of lag, exponential, decelerating, and stationary phases.
Each developmental term correctly pairs with its unique physiological mechanism: apical meristems facilitate primary terminal elongation, hypogeal germination maintains cotyledons sub-surface, ecdysis allows arthropod growth by molting the exoskeleton, and the sigmoid curve represents the standard four-stage growth kinetic trajectory.
