Explain the process/ methods of excretion in plants/ how does excretion occur in plants?

-Transpiration; Excess water is lost in form of vapour; through stomata/ lenticels;
-Diffusion; carbon (IV) oxide (from respiration) and oxygen (from photosynthesis) are eliminated through diffusion; through lenticels/ cuticle/ stomata;
-Deposition/ storage in non-toxic form; some wastes (e.g. calcium oxalate, caffeine, nicotine and quinine) are stored in tissues (e.g. leaves, fruits, flowers, bark) in non-toxic form;
-Tissue/ organic fall; plants store some of their wastes in flowers, fruits, seeds, old leaves and the bark and when these organs fall off from the plants, the wastes are eliminated;
-Exudation; some wastes (e.g. latex, salts, gum, calcium pectate, resins) are excreted in semi-solid form;
-Guttation; excess water is excreted in form of droplets through hydathodes;
