Wasbury effect – inhibitory effect of high concentration of O2 on photosynthesis in C3 plants, due to competition between CO2 & O2 for public C4 are insensitive to such change.
CAM pathway – CO2 us fixed at night & make glucose during day, in cactus etc., Calvin cycle CAM separated in time stored as u – c malic acid.
Law of limiting factor – when biological process is condition as to its rapidity by number separate factors, rate of process limited by the slowest factor.
in terrestrial plants called C13 discrimination (C4 has from C23 then C3 plants sugar from sugar cane (C4) is sweeter than sugar beet (C3) plants)
Photosynthesis = anabolic, endergonic, Oxidative – reductive
Destruction of chlorophyll due to high light intensity = Solarization most common limiting factor of photosynthesis = CO2.
Compensation point – photosynthesis = respiration
D eMU (di-chloro phenyl dimethyl urea) – O2 release
C3 plant – more CO2 is released in light than dark phase & increment with increment of CO2
Chlorophyll unit in leaves of difference ages plants = assimilatory power it decrement with age of plant.
12+ help in translocation of food = active process
Presence of labelled sugar in phloem showed that solutes are transport through phloem.
If tree ringed, roots die 1st, ringing not successful in monocot open Vascular bundle
Ringing done below fruits – fruits will be bigger in size.
Ringing done between fruits & leaves – fruits will be smaller in size
CO2 concentration is more before sunrise (start of photosynthesis ) So CO2 + H2CO3 lower pH
Photo excitation Occurs in chl. molecules
Protochl converts to Chl ( in presence of C7 & C8 of same pyrrole ring (IV) and +24 atoms)
Jenner – against smallpox
Pasteur – against rabies.
Infective nature of TMV – merger
Contagium vivum fluidum – Beijerinck.
More diversity found in genome of virus.
M. Schlesinger isolated virus bacteriophage WLL made of protein H3PO4
Vision – Fully assembled mature particle of virus capable of infection.
Smallest virus = coli phage F2
Smallest plant virus = Tobacco necrosis virus.
Longest plant virus = Citrus Trist age virus.
Smallest animal virus = foot & month disease of cattle.
Largest animal virus = pore – parrot fever virus.
Arboviruses = Arthropod borne virus Reovirus – Respiration enteric orphan virus.
Capsomere are proteinaceous (Each present in protomere)
Capsomere highly synthesis structure which can be crystallized
Total capsomere = 10 (n – 1)2 + 2 n = number of capsomere on one edge Example-Adenovirus (6 = n) so total = 252
