Biomass allocation is the result of a number of processes which take place in the plant. It starts with the way sugars are allocated to different organs after having been fixed by the leaves in the process of photosynthesis (sugar allocation).
The reward system (the mesocorticolimbic circuit) is a group of neural structures responsible for incentive salience (i.e., "wanting"; desire or craving for a reward and motivation), associative learning (primarily positive reinforcement and classical conditioning), and positively-valenced emotions, particularly ones involving pleasure as a core component (e.g., joy, euphoria and ecstasy).
Photosystem I (PSI, or plastocyanin–ferredoxin oxidoreductase) is one of two photosystems in the photosynthetic light reactions of algae, plants, and cyanobacteria. Photosystem I [1] is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from plastocyanin to ferredoxin.
Plant-based drugs, however, have reinforcing and rewarding effects on the human neurological system, suggesting a "paradox of drug reward" in humans. [24] Human behavioral evolutionary mismatch explains the contradiction between plant evolution and human drug use.
In physiology, a stimulus [1] is a change in a living thing's internal or external environment.This change can be detected by an organism or organ using sensitivity, and leads to a physiological reaction. [2]
In 2018, Bar-On et al. estimated the total live biomass on Earth at about 550 billion (5.5×10 11) tonnes C, [1] most of it in plants. In 1998 Field et.al. estimated the total annual net primary production of biomass at just over 100 billion tonnes C/yr. [ 4 ] The total live biomass of bacteria was once thought to be about the same as plants ...
Floral biology is an area of ecological research that studies the evolutionary factors that have moulded the structures, behaviours and physiological aspects involved in the flowering of plants. The field is broad and interdisciplinary and involves research requiring expertise from multiple disciplines that can include botany, ethology ...
Ecophysiology (from Greek οἶκος, oikos, "house(hold)"; φύσις, physis, "nature, origin"; and -λογία, -logia), environmental physiology or physiological ecology is a biological discipline that studies the response of an organism's physiology to environmental conditions.
