From the following groups, select the one which has only secondary metabolites?
1 Arbrin, cellulose, arginine, tyrosine
2 Glycine, gums, serine, diterpenes
3 Carotenoids, phenylalanine, curcumin, rubber
4 Concanavalin-A,morphine,codeine,vinblastin
Explanation:
Exp: D Concanavalin- A, morphine, codeine, vinblastine are secondary metabolites. The secondary metabolites are the derivatives of the primary metabolites and they do not have any direct function in growth and development of plants.

Which of the following would not give Fehling's test?
1 Glucose
2 Sucrose
3 Fructose
4 Lactose.
Explanation:
Exp: B Fehling's test is given only by reducing sugars. When Fehling's solution is added to any reducing sugar then a red precipitate is formed which shows that reduction has taken place. Sucrose does not give this test. Presence of aldehyde but not ketones is detected by this test. The test will turn out to be positive only when a free aldehyde group is present. The Fehling's test does not detect presence of sugar, it can only detect sugar having aldehyde group.

Which of the following vitamins is essential for DNA synthesis and cell division?
1 Vitamin - A
2 Vitamin - D
3 Folic acid
4 Vitamin - K
Explanation:
Exp: C Folic acid is also known as vitamin B9. It is an essential nutrient necessary for protein and nucleic acid (DNA \& RNA) synthesis. It is an important part of cell division and in making cells in some organs and bone marrow.
