Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
In ecology and plant physiology, plants are classified based on their light intensity requirements. The prefixes "helio-" (sun) and "scio-" (shade) are used to describe their adaptation to solar radiation.
Step 2: Detailed Explanation:
A. Heliophytes: These are "sun-loving" plants. They are adapted to high light intensities and reach their maximum photosynthetic rate under bright sunlight. Examples include most fruit trees like Mango and Citrus. (Match with I: Plants which grow in open sunny situation).
B. Sciophytes: These are "shade-loving" or shade-tolerant plants. They can grow efficiently under low light intensities, such as on the forest floor or under a dense canopy. (Match with II: Plants which grow in shade).
C. Obligative Sciophytes: The term "obligative" implies a biological necessity. These plants must grow in the shade to survive; intense sunlight may actually damage their chlorophyll or lead to photo-inhibition. (Match with III: Plants which always grow in shade).
D. Obligative Heliophytes: These plants must have full sun throughout their life cycle. They cannot tolerate shade even for short periods and will show stunted growth or death if shaded. (Match with IV: Plants which always grow under sunny situation).
This classification is essential for orchard planning and intercropping. For example, shade-loving crops like Ginger or Turmeric (Sciophytes) are often grown as intercrops under the canopy of fruit trees (Heliophytes).
Step 3: Final Answer:
The logical pairing follows the definitions: A-I, B-II, C-III, D-IV.
