Q40: Given below are two statements Statement (I): Hypodermal cells are... - Nematode Taxonomy and Morphology - Plant Pathology- ICAR JRF/SRF 2024 | Agrigyan

• Hydrostatic Skeleton and Turgor in Nematodes:
• Body Turgor Mechanics: Nematodes maintain a high internal hydrostatic pressure ($7.5-15\text{ kPa}$, up to $45\text{ kPa}$) in the pseudocoelomic fluid, which acts against the rigid, non-elastic multi-layered collagenous cuticle to maintain cylindrical body shape and power sinusoidal locomotion.
• Evaluation of Statements:
• Statement (I) is incorrect because hypodermal cells secrete cuticle and store glycogen/lipids, but do not directly generate internal body turgescence.
• Statement (II) is evaluated: while pseudocoelomic hydrostatic pressure provides the physical turgor, in examination keys both statements were judged incorrect regarding the cellular origin of turgor (Option 2).

Correct option: (2) Both Statement (I) and Statement (Il) are incorrect
