Plants need nitrogen, phosphorus, and potassium, as well as micronutrients and symbiotic relationships with fungi and other organisms to flourish, but getting enough nitrogen, and particularly synchronization so that plants get enough nitrogen at the right time ( when plants need it most ), is likely the greatest challenge for organic farmers.

Plants need to absorb mineral salts from the soil or other sources, but these salts exist in very dilute solution.

Plants need hormones at very specific times during plant growth and at specific locations.

Plants need to be chosen with care as they can grow to a substantial size.

Plants raised in protected conditions usually need a period of acclimatization, known as hardening off.

Plants can be damaged by high fluoride or boron levels.

Plants are the fundamental base of nearly all food chains because they use the energy from the sun and nutrients from the soil and atmosphere, converting them into a form that can be consumed and utilized by animals ; this is what ecologists call the first trophic level.

Plants acquire it through photosynthesis, and animals acquire it from consumption of plants and other animals.

Examples would be " Human beings typically have two eyes, two ears, two hands, two feet ", or " The world has a ground and a sky " or " Plants and animals come in a wide variety of sizes and colors " or " I am conscious and alive right now ".

Plants, animals, fungi, bacteria, and humans affect soil formation ( see soil biomantle and stonelayer ).

Plants also have respiratory systems but the directionality of gas exchange can be opposite to that in animals.

Plants and animals moved throughout the world due to human movements.

Plants fix atmospheric carbon during photosynthesis, so the level of < sup > 14 </ sup > C in plants and animals when they die approximately equals the level of < sup > 14 </ sup > C in the atmosphere at that time.

Plants and animals living in those parts of the world where such events occurred were often killed off according to Cuvier.

) Plants did have greater tolerances for heat and cold, and immunity to the pain that afflicts most animals.

Plants and animals in deserts and xeric shrublands are adapted to low moisture conditions.

Plants, unlike animals, lack glands that produce and secrete hormones.

Plants lack glands to produce and store hormones, because, unlike animals — which have two circulatory systems ( lymphatic and cardiovascular ) powered by a heart that moves fluids around the body — plants use more passive means to move chemicals around the plant.

; Plants and animals

Plants such as Homerias, Watsonias and Gladioli, genera that are vulnerable to such animals, are probably the ones that produce cormels in the greatest numbers and most widely distributed over the plant.

Plants and wild animals on Amrum are marked by the proximity to the sea, but some also distinguish themselves by extreme rarity and a high ecological value worth of protection.

Plants and animals utilize carbon to produce carbohydrates, fats, and proteins, which can then be used to build their internal structures or to obtain energy.

Plants and animals temporarily use carbon in their systems and then release it back into the air or surrounding medium.

Plants and animals extract nutrient minerals from rocks and release oxygen in the process.

# Animation – Hand Plants and Things: An animation by Terry Gilliam depicting cut-out hands as plants and animals.

Plants and animals play a huge role in the health of our ecosystems.

Plants and animals both inhabit areas that they are not intended to be.

Plants, in turn, provide energy for other forms of life, such as animals.

* " Plants / Animals " – Plants, animals, items made from plants or animals

Plants may absorb styrene and pass it to their consumers ; this is a possible health risk.

Plants such as wild garlic, nettles and watercress may have been gathered in the wild.

Plants that avoid the effects of high salt even though they live in a saline environment may be referred to as facultative halophytes rather than ' true ', or obligatory, halophytes.

Plants may then die as a result from this, resulting in the soil or substrate nutrients previously used by the original plant to become more freely available to kudzu.

Plants of many species may grow either into shrubs or trees, depending on their growing conditions.

Plants grown from seed may take more than eight years to flower.

Plants whose distinctive characters are derived from the presence of an intracellular organism may also form a cultivar provided the characters are reproduced reliably from generation to generation.

Plants of the same chimera ( which have mutant tissues close to normal tissue ) or graft-chimeras ( which have vegetative tissue from different kinds of plants and which originate by grafting ) may also constitute a cultivar.

Names of cultivars are regulated by the International Code of Nomenclature for Cultivated Plants, and may be registered with an International Cultivar Registration Authority ( ICRA ).

Plants protected by Plant breeders ’ rights ( PBR ) may have a " true " cultivar name – the recognized scientific name in the public domain, and a " commercial synonym " an additional marketing name that is legally protected: an example would be Rosa < tt > Fascination </ tt > = ' Poulmax ', the ‘ Poulmax ’ being the true scientific name.

Plants may bear fruit of all descriptions ( pie trees and shoe trees are common ) or they may be carnivorous ( such as the tangle trees ), making travel in Xanth risky.

Plants may be consisidered pests if an invasive species.

Plants within Garryales may be cultivated for ornamental purposes ; Aucuba japonica is grown as a decorative hedge.

Plants that do not use pumped-storage are referred to as conventional hydroelectric plants ; conventional hydroelectric plants that have significant storage capacity may be able to play a similar role in the electrical grid as pumped storage, by deferring output until needed.

Plants moved from one area of the world to another may not always be accompanied by their pollinating partner and the lack of pollinators has spurred human cultivation of parthenocarpic varieties.

Plants that are typical of these habitats including a variety of reeds, rushes and sedges as well as yellow flag, valerian and meadowsweet may be found.

Plants that are predominantly low to the ground or freshly planted are the most susceptible, and the phytotoxicity may prevent germination of some seeds.

Plants may be propagated by seeds, but often desirable cultivars are propagated asexually by budding, grafting, layering, or other nursery techniques.

Plants of the Hamamelidaceae have sticky pollen, which may have influenced the type of pollination that is seen in this family.

Plants in this subfamily may be annual or perennial herbs or shrubs, with either a prostrate or an erect stem.

Plants often grow in dense clumps in mud along the shores of ponds or streams, or they may grow submerged in shallow water with some of the leaves extending to float on the water surface.

Plants with leaves damaged by the disease may have up to 50 % lower yield of fruit.
