The enzyme that catalyzes the conversion of glucose to glucose-6-phosphate is: MCQ with Answer and Explanation

Explanation:
Robert Hooke, in his 1665 book 'Micrographia', described observing dead cork tissue under a microscope and coined the term 'cell' for the small, box-like compartments he saw. Antonie van Leeuwenhoek, using his superior handcrafted single-lens microscopes in the 1670s, was the first person to observe and describe living, single-celled microorganisms, which he called 'animalcules'. Charles Darwin proposed the theory of evolution by natural selection; the cell theory was proposed by Schleiden and Schwann. Thus, statements 1 and 2 are correct.

Explanation:
Gibberellins stimulate the synthesis of hydrolytic enzymes (e.g., amylase) that mobilize stored food reserves, promoting germination. Abscisic acid induces and maintains dormancy. Ethylene promotes ripening, auxin cell elongation.

Explanation:
Hydroponics involves growing plants with their roots in a mineral nutrient solution in water, without soil. This allows precise control of nutrients and is used in research and commercial production. Aquaculture is fish farming, tissue culture is in vitro plant propagation, vermiculture is earthworm composting.
