Floral chromosome = Basis of classification – floral features are conservative then vegetative -> venation is relied on classification for angiosperm

India’s largest herbarium – Calcutta (13-lakh specimen).
Solidago (Compositae) for dropsy
Labiatae = Mint family, Verticellaster inflorescence – sweet aromatic small
Photo autotrophic nutrition = Holophytic nutrition
Neottia – Bird nest orchid – humus rich soil – ectotrophic mycorrhiza
Monotropa – Indian pipe – humus rich soil – endotrophic mycorrhiza – pine forests
Dischidia = Pitcher plant but not insectivores.
Intervenial chlorosis – in young leaves – Fe
Intervenial chlorosis – in old leaver – mg
N2 defeciency – 1st chlorotic in older leaver.
Gold present in stem of Equisetum.
Prokaroyotes – utilize elemental N2 gas
Photolysis of H2O = Mn.

B – Heart rot of sugar beet, corky coke of apple, top sickness of tobacco, Celery stem crack, Brown heart or water core in turnip, Brown heart of cauliflower.
Cu – Die back of shoots
Cl – wilting of leaf tip followed by chlorosis, bronzing & necrosis basipetally in areas of proximate to wilting
Leg Hb – produced during maturation of reservoir of O2 & production of ATP, nodules keeps away O2 from nitrogenase
Membrane permeability – N2 & Ca
Nitrate reductase – Mo/flavorprotein
Nitrite reductase – Ferrodoxin.
Apoplast – nonliving, cellulosic cell wall, intercellular space(epidermis to xylem) – diffusion
Symplast – living, cytoplasm & plasmodesmate, active transport.
Hydrophonics – placing the roots in nutrient solation.
Aerophonics – growing plant in moist air laden with nutrients (Cytozyme – H2O soluble)
Liebig law of minimum – yield is determined by element present in minimum quantity in proportion to Lundergardh’s Cytochrome pump hypothesis – absorption of anion only immobile elements – Ca, S, Fe – Deficiency symptoms in young leaves. states that growth is controlled not by the total amount of resources available, but by the scarcest resource
Co – Algae, Microbes.
Na – Halophytes, Cu Pathway.
I2 – Marine algae.
Mo – needed in least quantity.
Plant ash – Contains oxides & Carbonates of elements
Most active free ion = K+
Sink is a region in which plant utilize a substances Translocate.
Bidirectional Translocation of minerals = Xylem.
Fall of immature leaf – deficiency of zinc.
