Agriculture Mcqs 7387 MCQs [All-Courses]

thumb

Agriculture MCQs cover fundamental and applied concepts related to farming, crop production, soil science, irrigation, fertilizers, plant breeding, pests, and agricultural economics. This topic is designed to strengthen conceptual understanding and problem-solving skills through objective questions. It is especially useful for competitive exams such as PPSC, FPSC, KPPSC, BPSC, NTS, OTS, and other testing services, helping candidates prepare with exam-oriented and up-to-date agricultural knowledge.

Mechanical tissues and xylem are highly reduced in Hydrilla because:
A Water provides the support and there is no problem for the absorption and conduction of water
B Otherwise the weight of these tissues would drown the plant
C Of the anaerobic conditions created by submergence
D Otherwise translocation of food would have been interrupted
Correct Answer: Water provides the support and there is no problem for the absorption and conduction of water
