Based on nature of substratum, plants are divided into different types. Which one is not one of those ?
Show Hint
Sciophytes are classified by light, not soil/substratum type
Updated On: Jul 4, 2026
- Oxylophytes
- Sciophytes
- Psammophytes
- Chasmophytes
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Ecological classification of plants by substratum (edaphic factors) includes groups like oxylophytes (plants of acidic, humus rich soils), psammophytes (plants growing on sandy substratum) and chasmophytes (plants growing in rock crevices).
Step 2: Sciophytes are shade-loving plants, this grouping is based on light availability, not on the type of substratum.
Step 3: Since the question asks for substratum-based groups, the one that does not belong here is sciophytes.
