hormone balance, cell regulation, cell function, plant evolution,
host/parasite relations ..., the biology of grandpa in images

Green leaves, yellow leaves, dead leaves...
a summary of plants' evolution (logo)

|
|
|
Why such a titel? In order to permit to Charlie, and to all the children in the world, to say, one day, studying their lessons: that's Grandpa's biology!

Cell function, in the case
of unicellular organisms

Cells function, in the case
of pluricellular organisms

The black arrows correspond to reactions of synthesis and degradation requiring the intervention of specific enzymes..., the white arrows indicate that these are simple reactions of exchange, balance, regulation - hypothesis 05.
|
|
|
|
The notions of balance and regulation, two sides of the same problem... In this case: the evolution of the host/parasite relations existing between the variety of tomato Supermarmande and the fungus Fusarium lycopersi, in relation with auxin and gibberellin treatments - first tests.
