Vitamins And Nutrition

Step 1: Understanding nutrient sources.
While irrigation and atmospheric deposition can provide some nutrients, they primarily supply water and trace elements. Root exudates mainly involve organic compounds affecting nutrient availability but not supplying the major elements directly.
Step 2: Role of fertilizers.
Fertilizers are specifically formulated to provide plants with essential nutrients such as Nitrogen (N), Phosphorus (P), and Potassium (K). These macronutrients are vital for various physiological activities in plants including growth, root development, and photosynthesis.

Analyzing each food item for associated nutrients.
A (Lablab): Often associated with enriched protein content due to its legume family characteristics, thus A matches with II.
B (Golden Rice): Genetically engineered to be rich in Vitamin A, specifically beta-carotene, hence B matches with I.
C (Pumpkin): Well-known for its high Vitamin A content, notably beta-carotene, making C a match with IV.
D (Bitter gourd): Recognized for its high Vitamin C content, D matches with III.

Step 1: Understanding the Terms
Self-Sterility (Self-Incompatibility) refers to the inability of a flower to fertilize itself, preventing self-pollination.
However, Gloriosa does not exhibit self-sterility, making this an incorrect match.
Herkogamy is a structural adaptation in flowers where physical barriers prevent self-pollination.
It is seen in Hibiscus, making this a correct match.
Protandry is when the male reproductive part (anther) matures before the female part (stigma), promoting cross-pollination, as seen in Sunflower.
Protogyny is when the female reproductive part (stigma) matures before the male part (anther), promoting cross-pollination, as seen in Datura.
Step 2: Identifying the Incorrect Match
Since Gloriosa does not exhibit self-sterility, the incorrect match is (1) Self-Sterility - Gloriosa.
