IV) Mechanical tissues are well developed in submerged water plants.

• A. I and II
• B. III and IV
• C. II and III
• D. I and IV

Hint:

CAM plants and physical adaptations in hydrophytes are common test points in ecology.

Answer 1

The Correct Option is A

I) Correct — CAM is found in desert plants to conserve water.
II) Correct — Earth’s axial rotation leads to seasonal variation.
III) Incorrect — Ecology studies interaction between organisms and environment, not only environmental changes.
IV) Incorrect — Mechanical tissues are reduced in submerged hydrophytes.
