plant-biophysics
Plant biophysics applies the principles of physics—such as mechanics, fluid dynamics, and energy transfer—to understand how plants function at cellular and whole-organism scales. It matters for plant science because it reveals the physical mechanisms behind processes like water transport, cell wall expansion, and structural support, helping explain how plants grow, respond to environmental stress, and maintain their form under physical forces like wind or gravity.

A new theoretical model proposes that plants grow primarily because of heat rather than light: rising tissue temperature lowers electrical resistance and boosts an internal voltage that drives growth, with light acting only as one possible heat source among several.
Proposes a four-field coupled model linking light, heat, electricity, and water within an individual plant's growth process
Argues rising tissue temperature lowers electrical resistance and raises voltage, framing the plant as a 'biological thermal power plant' that determines growth strength
Cites underground seed germination and nighttime growth (both without light) as evidence that heat, not light, is the primary growth driver
