Which of the following plays the major role in providing support to young herbaceous parts of the plant?
Correct answer: D. All of these
- A. Higher turgor pressure
- B. Cortex and pith with higher turgor pressure
- C. Collenchyma cells
- D. All of these
Explanation
Option A: A Higher turgor pressure: The pressure exerted by the fluid inside plant cells against the cell wall, providing support to young herbaceous parts. Option B: Cortex and pith with higher turgor pressure: The regions in the stem containing parenchyma cells that store water and contribute to the rigidity and support of young herbaceous parts. Option C: Collenchyma cells: Elongated cells with thickened cell walls that provide mechanical support and flexibility to growing herbaceous parts of a plant. Option D: All the options listed play a role in providing support to young herbaceous (soft and nonwoody) parts of the plant.

About Support and Movement
Support and movement covers the axial and appendicular skeleton, bone structure, joints and the arrangement of skeletal muscles. Muscle contraction is explained through actin, myosin, sliding filaments, calcium ions and ATP, while arthritis is distinguished as a disorder of joints rather than a normal part of movement.
