Informally known asbryophytes, nonvascular plants lack specialized vasculartissue(xylemandphloem) for internal water and food conduction and support. They also do not possess trueroots,stems, orleaves. Some largermosses, however, contain a central core of elongated thick-walled cells calledhydroidsthat...

The decrease in water supply reduces the availability of essential nutrients to the plant, which therefore reduces growth, characterized by the decrease in various growth parameters such as plant height, fresh and dry weight of shoots and roots, number of leaves per plant, number of branches per...
There are also many new but chemically unrelated compounds with similar hormone-like activity being produced. A better knowledge of the uptake, transport, metabolism, and mode of action of phytohormones and the appearance of chemicals that inhibit synthesis, transport, and action of the native plant...
In this review, we made an attempt to create a holistic picture of plant response to a rising temperature environment and its impact by covering all aspect
