Question

Boron in green plants assists in

• A. Sugar transport
• B. Activation of enzymes
• C. Acting as enzyme cofactor
• D. Photosynthesis

Answer 1

Answer: (A)

Sugar transport

Boron is a micronutrient which plays a key role in the development of plants and performs a variety of functions such as pollination, seed set, cell wall formation, maintenance of the structural and functional integrity of plant cells and movement of sugar or energy in the growing parts of the plants. The process of photosynthesis by green parts of the plant converts sunlight into chemical energy and forms sugars. But it is also essential that these sugars should be translocated to other parts of the plant. The rate of sugar transport in increased by the boron in growing regions and developing fruits. Theses sugars help in root growth in young plants and also in root nodule formation in leguminous plants.

Thus, the correct answer is option A.
