Monera, peptidoglycan
Which specific characteristic of algin in Phaeophyceae contributes significantly to its commercial applications as a stabilizing agent?
Its high cellulose content providing structural rigidity
Its ability to form viscous gels in the presence of divalent cations
Its potent antimicrobial properties preventing spoilage

Which of the following is NOT a characteristic feature of collenchyma cells?
Presence of lignin in cell walls
Unevenly thickened cell walls
Living cells at maturity
Provides flexible support to the plant
Which statement BEST describes the relationship between collenchyma and sclerenchyma?
Both are composed of living cells at maturity.
Both have evenly thickened cell walls.
Both contain lignin in their cell walls.
Both provide structural support, but collenchyma provides flexible support in growing regions while sclerenchyma provides rigid support in mature regions.
Which component is primarily responsible for the thickening of collenchyma cell walls?
Pectin
Lignin
Suberin
Cutin
