Emoto claimed that water was a "blueprint for our reality" and that emotional "energies" and "vibrations" could change its physical structure. [14] His water crystal experiments consisted of exposing water in glasses to various words, pictures, or music, then freezing it and examining the ice crystals' aesthetic properties with microscopic photography.

A tomato greenhouse in the Netherlands. The advantage of mesocosm studies is that environmental gradients of interest (e.g., warming temperatures) can be controlled or combined to separate and understand the underlying mechanism(s) affecting the growth or survival of species, populations or communities of interest.
Later, the cytological basis of the gene-chromosome theory of heredity extended from about 1900–1944 and was initiated by the rediscovery of Gregor Mendel's (1822–1884) laws of plant heredity first published in 1866 in Experiments on Plant Hybridization and based on cultivated pea, Pisum sativum: this heralded the opening up of plant genetics.
A plant which completes its life cycle (i.e. germinates, reproduces, and dies) within two years or growing seasons. Biennial plants usually form a basal rosette of leaves in the first year and then flower and fruit in the second year. bifid Forked; cut in two for about half its length. Compare trifid. bifoliate
The experiment was only published posthumously in Ortus Medicinae (1648) and may have been inspired by similar experiments by Santorio, published in Ars de statica medicina (1614). Helmont grew a willow tree and measured the amount of soil, the weight of the tree and the water he added. After five years the plant had gained about 164 lbs (74 kg).
1863 – Gregor Mendel's pea plant experiments (Mendel's laws of inheritance). 1887 – Heinrich Hertz discovers the photoelectric effect. 1887 – Michelson and Morley: Michelson–Morley experiment, showing that the speed of light is invariant. 1896 – Henri Becquerel discovers radioactivity. 1897 – J. J. Thomson discovers the electron.

Hydrotropism (hydro- "water"; tropism "involuntary orientation by an organism, that involves turning or curving as a positive or negative response to a stimulus") [1] is a plant's growth response in which the direction of growth is determined by a stimulus or gradient in water concentration. A common example is a plant root growing in humid air ...
