Multiple Choice Questions

Question 1: The chemical which are produced byhost plants due to infection as a defence reaction to pathogen, are called
(a) phytotoxin
(b) toxin
(c) phytotron
(d) phytoalexins
Show Answer & Explanation

Answer: (d) phytoalexins

Explanation:
1. Phytoalexins are antimicrobial chemicals made by plants after infection as a defence against the pathogen.
2. Phytotoxins and toxins are poisons made by organisms.

Teacher's Note:
1. A phytotron is a plant growth chamber.

Question 2: Crop rotation is used to increase
(a) soil fertility
(b) pore size and soil particle
(c) organic content of soil
(d) viscosity of soil water
Show Answer & Explanation

Answer: (a) soil fertility

Explanation:
1. Crop rotation, growing different crops (legume and non-legume) in turn on the same land, restores and increases soil fertility.
2. Legumes fix nitrogen and the following crop uses it.

Teacher's Note:
1. It also breaks pest cycles.

Question 3: Haploid cultures can be obtained by culturing
(a) pollen grains
(b) embryo
(c) shoot apex
(d) root apex
Show Answer & Explanation

Answer: (a) pollen grains

Explanation:
1. Haploid plants are obtained by culturing pollen grains (anther culture), since pollen has half the chromosome number.
2. Embryo, shoot apex and root apex are diploid tissues.

Teacher's Note:
1. The haploid plants are doubled with colchicine.

Question 4: Azolla is used as a biofertilizer because it
(a) multipliesveryfasttoproducemassivebiomass
(b) hasassociation ofnitrogen-fixingRhizobium
(c) hasassociationofnitrogen-fixingCyanobacteria
(d) hasassociation of mycorrhiza
Show Answer & Explanation

Answer: (c) hasassociationofnitrogen-fixingCyanobacteria

Explanation:
1. Azolla is a water fern that hosts the nitrogen-fixing cyanobacterium Anabaena, so it is used as a biofertiliser in rice fields.
2. Rhizobium lives in the legume roots.

Teacher's Note:
1. Mycorrhiza help absorption of phosphorus.

Question 5: Somaclonal variation can be obtained by
(a) application of colchicine
(b) irradiation with gamma rays
(c) tissue culture
(d) hybridisation
Show Answer & Explanation

Answer: (c) tissue culture

Explanation:
1. Somaclonal variations arise in plants raised from callus by tissue culture.
2. Useful ones are selected for new varieties.

Teacher's Note:
1. Colchicine and gamma rays act as mutagens.

Question 6: A scion is grafted to a stock. The quality of fruits produced will be determined by the genotype of
(a) stock
(b) scion
(c) both stock and scion
(d) neither stock nor scion
Show Answer & Explanation

Answer: (b) scion

Explanation:
1. In grafting the scion supplies the shoot system, so the fruit quality is determined by the genotype of the scion.
2. The stock gives the root system.

Teacher's Note:
1. The scion keeps its own characteristics.
