Collenchyma occurs in:
Correct answer: C. Climbing stems
- A. Herbaceous climbers
- B. Woody climbers
- C. Climbing stems
- D. Water plants
Explanation
Collenchyma occurs in climbing stems. Collenchyma occurs in the stem and petioles of dicot herbs. Due to the deposition of pectin, it has high water-retaining capacity. Since pectin appears at the angles, it becomes a spongy tissue. The collenchyma is a mechanical tissue that gives tensile strength to the plant.

About Growth and Development
Embryonic development covers fertilization, cleavage, formation of the blastula and gastrula, germ layers, organ formation and differentiation. Regeneration describes the replacement of lost tissues or body parts, whereas ageing involves gradual cellular and physiological changes linked to reduced repair, altered metabolism and declining organ function.
