Xerophytes ( Xero - Dry & phytes - Plant ) . Xerophytes are called " Dry Plants " because they need very little water to survive.
A thylakoid is a compartment present inside chloroplasts* and cyanobacteria**. They are the sites responsible for light dependent reactions during photosynthesis. They consist of a thylakoid membrane surrounding a thylakoid lumen. *a plastid in green plant cells which contains chlorophyll. **a bacteria which obtain energy from photosynthesis. A VERY EASY TOPIC IF YOU ARE ABLE TO UNDERSTAND IT.
pH scale is a numerical representation of acidity and basicity of the substances. It varies from 1 to 14. The solutions with a pH value less than 7 are referred to as bases and those with a pH value of 7 are to as neutral.
pH value are the value used to determine wheather a solution is acid or basic in nature Acids= pH<7 Bases= pH>7 Neutral= pH=7
-pH stands for potenz Hydrogen, pH value indicates whether the substance is acidic, basic of neutral. - pH less than 7 is acidic -pH greater than 7 is basic - pH equal to 7 is neutral ( neither acidic nor basic)
