Nutrition in Plants & Animals (Photosynthesis & Food Substances)
Solution
A food substance was treated with a few drops of Sudan III solution and a red coloration was obtained. The food contained
A
protein
B
starch
C
fat
D
mineral salt
medium Difficulty
Verified Correct Answer: Option C
Biological Concept & Syllabus Guide
To test for fats using Sudan III solution, add a few drops of the sample to a test tube, then add Sudan III reagent. If lipids are present, the solution will turn red as the dye binds to the lipids. Sudan III is a fat-soluble dye that readily binds to lipids (fats and oils).

Respiration & Gaseous Exchange
Solution
Adaptive features of plants to desert conditions include?
A
thick barks, succulent stems and sunken stomata
B
thin barks, succulent stems and sunken stomata
C
thin barks, air floats on stems and sunken stomata
D
air spaces in tissues, adventitious roots and thick barks
medium Difficulty
Verified Correct Answer: Option A
Biological Concept & Syllabus Guide
The leaves and stems of many desert plants have a thick, waxy covering.
This waxy substance does not cover the stomata, but it covers most of the leaves, keeping the plants cooler and reducing evaporative loss.
Small leaves on desert plants also help reduce moisture loss during transpiration.
Eg cactus plants: · thick, waxy skin to reduce loss of water and to reflect heat · large, fleshy stems to store water · thorns and thin, spiky or glossy leave
