Question

The uptake and utilisation of calcium is supported by-
A. Molybdenum
B. Zinc
C. Boron
D. Manganese

Answer 1

Hint: When we talk about calcium first we need to think where is calcium present in the plant or what does it help in. Whenever a calcium word comes to our mind it is linked with strength. Plant cell is a very rigid layer which is made up of cellulose, glycoproteins, lignin, pectin and hemicellulose. It is located just outside the cell membrane. It comprises proteins, polysaccharides and cellulose.

Complete answer:
Boron is a very essential type of micronutrient for plants. Its main function is related to the cell wall strength and its development, cell division, fruit and seed development, transport of sugar and hormonal development. Boron is closely associated with calcium.
Boron along with calcium (Ca) in cell wall structure. Boron is also involved in the movement of Ca into the plants and also in normal Ca nutrition in plants as well as animals.

Hence, the correct option is option C i.e. Boron.

Additional information: The other functions of boron is it acts as a partner with calcium helps in cell wall formation. It also helps in uptake and absorption of calcium. At high pH and high humidity the plant will not be able to absorb boron so these factors act as its limiting factor. It also helps in germination of pollen grain.

Note: The primary function of the cell wall is to protect from surroundings and provide structural support to the cell. Nutrients required by plants are further required in various metabolism occurring in plants.
