Calcium oxalate (CaOx) crystals are distributed among all taxonomic levels of photosynthetic organisms from small algae to angiosperms and giant gymnosperms. Calcium serves as an important macronutrient for plants to grow. They are used as a calcium pectinate to form the middle lamella in the cell wall for the metabolism of lipids. Exchangeable calcium and magnesium are attracted to negatively charged sites on clay and organic matter in soil where they are not easily leached from the soil but are available to plants. In water and sewer treatment plants, calcium carbonate is employed in the removal of acidity and impurities. In plants, calcium is the third most abundant element after nitrogen and potassium. In both plant and animal cells secretion appears to be dependent on, or is triggered by, a rise in the level of internal free calcium ions from about 10 ‐7 to 10 ‐6 M or even higher.
