Plants sprayed with 2,4-D may accumulate lethal doses of nitrates. [25] 'The troublesome weed' – hence an excellent source of bioenergy. The troublesome weed' – hence an excellent source of bioenergy.
A hyperaccumulator is a plant capable of growing in soil or water with high concentrations of metals, absorbing these metals through their roots, and concentrating extremely high levels of metals in their tissues. [1] [2] The metals are concentrated at levels that are toxic to closely related species not adapted to growing on the metalliferous ...
Large number of seeds can accumulate in the soil of wetlands. [5] [11] Peltandra virginica is a marshland aquatic plant, growing in North America bogs, ponds, and marshes. The roots and base grow into the submerged substrate, and the leaves and inflorescences project up and out of the water. The roots form a perennial rhizome. Various forms of ...
A druse is a group of crystals of calcium oxalate, [1] silicates, or carbonates present in plants, and are thought to be a defense against herbivory due to their toxicity. Calcium oxalate (Ca(COO) 2 , CaOx) crystals are found in algae , angiosperms and gymnosperms in more than 215 families.
A typical recipe for the production of a zeolite includes the mineralizer, the solvent, the seed crystal, a nutrient consisting of silica (SiO 2) and alumina (Al 2 O 3), and a template. Templates are cations that direct the polymerization of the anionic building blocks to form a certain zeolite structure.
A container garden in large plastic planters. Container or bucket gardening involves growing plants in some type of container, whether it be commercially produced or an everyday object such as 5-gallon bucket, wooden crate, plastic storage container, kiddie pool, etc. Container gardening is convenient for those with limited spaces because the containers can be placed anywhere and as single ...

The primary focus is on plants, but they will sometimes also house waterfowl , or ornamental fish , in which case it may be called a fish pond .
A seed crystal is a small piece of single crystal or polycrystal material from which a large crystal of typically the same material is grown in a laboratory. Used to replicate material, the use of seed crystal to promote growth avoids the otherwise slow randomness of natural crystal growth, and allows manufacture on a scale suitable for industry.
