Deficiency of Sulphur can cause all in a plant except..

Options:
A Chlorosis
B Inhibition of cell Division
C Necrosis
D Delay in flowering

The correct answer is:
Necrosis

Solution:
Chlorosis is the loss of chlorophyll leading to yellowing in leaves. This symptom is caused by the deficiency of elements N, K, Mg, S, Fe, Mn, Zn and Mo. Likewise, necrosis, or death of tissue, particularly leaf tissue, is due to the deficiency of Ca, Mg, Cu, K. Lack or low level of N, K, S, Mo causes an inhibition of cell division. Some elements like N, S, Mo delay flowering if their concentration in plants is low.

Deficiency of the enzyme ADA causes

Options:
A

Hypogammaglobulinemia

B

Agammaglobulinemia

C

Acquired immunodeficiency disease

D

Severe combined immunodeficiency disorder

The correct answer is:

Severe combined immunodeficiency disorder

Solution:
Adenosine deaminase (ADA) is very crucial for immune systems to function. The deficiency of ADA causes severe combined immune deficiency disease. The patent lacks functional T-lymphocytes and fails to fight infectious pathogens. Using the gene-therapy lymphocytes is extracted from the patientâs bone marrow and a normal functional gene for ADA is introduced into their lymphocytes with the retrovirus. The lymphocytes of bone marrow contain the functional ADA gene and reactivate the patientâs immune system.

In some children, ADA deficiency can be cured by bone marrow transplantation, in other, it can be treated by enzyme replacement therapy, in which functional ADA is given to the patient by injection.

Deficiency of which of the following elements leads to discolouration of plant parts?

Options:
A Na
B Ca
C Cu
D P

The correct answer is:
P

Solution:
Phosphorous is absorbed as phosphates which is an important constituent of the cell membrane, proteins. Also, phosphorus is necessary for the phosphorylation process. Deficiency leads to abnormal discolouration of the plant parts. Calcium is an important constituent required by meristematic and differentiating tissues. Calcium deficiency leads to localized necrosis and stunted growth.

Copper occurs in almost every type of soil in the form of complex organic compounds. It helps in activating many enzymes and part of plastocyanin. Plastocyanin is important for photophosphorylation process. Its deficiency reduces the growth in plant.
