Answer:
Magnesium, calcium, phosphorous, sulfur these are essential nutrients for plants. These are required in trace quantity but are very important for plant life. Point A. will be correct answer.
Explanation:
As in B. starch n cellulose are composed of only carbon, oxygen and hydrogen.
As in C. These elements are not required on special occasion but are necessary throughout plant life.
As in D. C H N O is the primary component plants need but these secondary nutrients are equally necessary for growth n structure of plant.
<u><em>So answer A. Is the correct option.</em></u>
Calcium plays the most important role in structure formation of plants. Also act as messenger molecule in signaling. Deficiency of calcium caused wilting , weakened stem and ultimately death of plant.
Magnesium is the key element in chlorophyll molecule. It is necessary for chlorophyll formation.
Sulfur is another very important element in plant life, it is necessary for protein synthesis in plants.
Phosphorous plays an important role in process of cell devision , photosynthesis and respiration.
Potassium is very crucial in gaseous exchange ,it operates the opening and closing of stomata.
Instead of roots, threadlike structures called rhizoids.

The correct matching of enzymes and their role in the process of DNA replication is A- 3, B- 5, C-1, D-2 and E-4.
Replication is the process of synthesis of two indentical copies of DNA from a single DNA molecule. It is catalyzed by a set of enzymes with the following function-
A. RNA primase synthesizes an RNA primer (short sequence of RNA) on the lagging strand complementary to the single stranded DNA which acts as template during DNA replication.
B. Ligase is involved in joining the okazaki fragments on the lagging strand together and sealing the nicks of the DNA strand.
C. Helicase separates the two DNA strands at the replication fork.
D. Polymerase synthesizes the complementary daughter strand by adding nucleotides to DNA.
E. Topoisomerase relaxes the highly coiled DNA by creating nick ahead of the replication fork in the phosphate backbone of DNA strands.
