Question 2(b)

Differentiate between the following pairs on the basis of what is mentioned in brackets: [5]

(i) Active Transport and Diffusion [significance in plants]

(ii) Demography and Population density [Definition]

(iii) Antibiotic and Antibody [Source]

(iv) Renal cortex and Renal medulla [Parts of the nephrons present]

(v) NADP and ATP [Expand the abbreviation]

Answer

(i) Difference between Active Transport and Diffusion [significance in plants]

Active TransportDiffusion
Certain nutrients such as ios of nitrates, sulphates, potassium, zinc, manganese, etc. are taken up by the roots from the soil through Active transport using the energy supplied by the cell in the form of ATP.Carbon dioxide needed for the process of photosynthesis enters the leaf through the stomata by the process of Diffusion.

(ii) Difference between Demography and Population density [Definition]

DemographyPopulation density
Statistical study of human population with reference to size, density and distribution.Number of individuals per square km at any given time.

(iii) Difference between Antibiotic and Antibody [Source]

AntibioticAntibody
They are the medicines extracted from some bacteria and fungi. Antibiotics destroy or inhibit the growth of pathogens.They are produced by lymphocytes in response to the entry of pathogens in the bloodstream.

(iv) Difference between Renal cortex and Renal medulla [Parts of the nephrons present]

Renal cortexRenal medulla
Bowman's capsule, Proximal Convoluted Tubule (PCT), Distal Convoluted Tubule (DCT) are present in Renal cortexLoop of Henle and Collecting Ducts are present in Renal medulla

(v) Difference between NADP and ATP [Expand the abbreviation]

NADPATP
Nicotinamide Adenine Dinucleotide PhosphateAdenosine Tri Phosphate.
