Vedclass · Answer

(A) Diatoms are the chief producers in the oceans and are very important photosynthesizers.Their cell walls are embedded with silica,forming large deposits known as 'diatomaceous earth' or 'diatomite'.Diatomite deposits are often accompanied by petroleum fields.Due to their gritty nature,they are used in polishing,filtration of oils and syrups,and as an abrasive in toothpastes.Mycorrhiza is a symbiotic association between fungi and the roots of higher plants.It helps the plant in the absorption of phosphorus from the soil and provides resistance to root-borne pathogens.
