The phenomenon of a plant flowering in response to the length of day is called: MCQ with Answer and Explanation

Explanation:
Antonie van Leeuwenhoek, a Dutch microscopist, designed single-lens microscopes and observed bacteria, protozoa, sperm cells, and RBCs for the first time, calling them 'animalcules'. Hooke observed dead cork cells. Schleiden proposed that plants are composed of cells, Virchow stated 'Omnis cellula e cellula'. Leeuwenhoek is rightly considered the father of microbiology for his pioneering observations of living microbes.

Explanation:
Hydroponics is a method of growing plants in a water-based, nutrient-rich solution without soil. Aeroponics uses mist, geoponics is soil-based, tissue culture is in vitro on agar media. Hydroponics enables controlled nutrient delivery.

Explanation:
Sedimentary rocks, such as limestone, shale, and sandstone, form in layers from accumulated sediments and preserve remains of organisms as fossils. Igneous rocks from volcanic activity and metamorphic rocks formed under high temperature/pressure rarely contain fossils. The fossil record provides evidence for evolution, showing gradual changes in species over geological time. Fossils include bones, shells, imprints, and amber inclusions.
