Q 10 on imbibition

Image
Principle : In general, when seeds are immersed into water, the water is soaked up and the seeds swell up considerably,and the phenomenon is termed as imbibition. Since imbibition is a biological process temperature has an influence.So, van't Hoff's law will play a positive role on imbibition. The law states that, with a rise of every 10°C there is a doubling of the speed of the reaction .       Q10 is the measurement of the rate of change of a biological or chemical system as a consequence of increasing the temperature by 10°C. Hence, Q10 is a ratio of the two values of a biological system at two temperature differ by 10°C.                      (T2--T2)/10°C.                    Q10.                       =  R2/ R1, where R= the rate; T= temperature at Celsius ° or Kelvin ; Q10is unit...

Problems and Solutions in Mycology

Image
Topic 1 Degeneration  of sex in fungi          In Fungi, simplification of sex organs is observed from lower groups to upper groups:-       1.In Mastigomycotina,a lower group of fungi,isogamy,anisogamy or oogamy resulted into zygote.         2.In Ascomycotina & Basidiomycotina, the sexual reproduction process is progressively simplified in different directions with well- established sexuality.         3 Whereas ,sex organs are absent in few higher fungi of basidiomycotina,though sexual reproduction is well established. Degenaration sex in non - septate and ceonocytic fungi :-           1. The members of Oomycetes of Mastigomycotina , like Pythium , Phytophthora etc.female oogonium is fused by male antheridium to develop either oospore or zygote. It is considered as an advanced type of sexual reproduction.         2. In the members of...
