The term “plant strategies” has many definitions, and includes several different mechanisms for responding to one's environment. While different strategies focus on different plant characteristics, all strategies have an overarching theme: plants must make trade-offs between where and how to allocate resources. Whether that's allocation to ...
Plant defense against herbivory or host-plant resistance is a range of adaptations evolved by plants which improve their survival and reproduction by reducing the impact of herbivores. Many plants produce secondary metabolites , known as allelochemicals , that influence the behavior, growth, or survival of herbivores.
For example, jasmonic acid can be used to simulate an herbivore attack on plants and thus, induce plant defences. [19] The use of jasmonic acid on tomato ( Lycopersicon esculentum ) resulted in plants with fewer but larger fruits, longer ripening time, delayed fruit-set, fewer seeds per plant and fewer seeds per unit of fruit weight.

Plants can protect themselves from abiotic stress in many different ways, and most include a physical change in the plant’s morphology. Phenotypic plasticity is a plant’s ability to alter and adapt its morphology in response to the external environments to protect themselves against stress. [ 2 ]
It is the most popular system of classification especially for the flowering plant groups (angiosperms) based on key characteristics. This enables taxonomic students to quickly identify plant groups based only on physical characteristics. Under the system Heteromerae is a Sub Class, Series ii and it is often not used. The series comprises;
Some of the traditional tools of cultivated plant taxonomy including: microscope, camera, flowers and book to assist identification. Cultivated plant taxonomy is the study of the theory and practice of the science that identifies, describes, classifies, and names cultigens—those plants whose origin or selection is primarily due to intentional human activity.
Phytoremediation technologies use living plants to clean up soil, air and water contaminated with hazardous contaminants. [1] It is defined as "the use of green plants and the associated microorganisms, along with proper soil amendments and agronomic techniques to either contain, remove or render toxic environmental contaminants harmless". [2]
Plant perception is the ability of plants to sense and respond to the environment by adjusting their morphology and physiology. [1] Botanical research has revealed that plants are capable of reacting to a broad range of stimuli, including chemicals, gravity, light, moisture, infections, temperature, oxygen and carbon dioxide concentrations, parasite infestation, disease, physical disruption ...
