Concerning the second question, the recent investigations of Buchner ascogenous hyphae with their asci represent the sporophyte since they are derived from the fertilized ascogonium.
FRIEDRICH KARL CHRISTIAN LUDWIG BUCHNER (1824-1899), German philosopher and physician, was born at Darmstadt.
The point is that neither Buchner nor Haeckel could on their assumptions recognize any force but force of body, or any mind but mind of body, or any distinct thing or substance except body.
The remarkable discoveries of Fischer and Buchner to a great extent confirm Traube's views, and reconcile Liebig's and Pasteur's theories.
It has since been shown by Buchner and Albert that yeast-cells which have been killed by alcohol and ether, or with acetone, still retain the enzyme.
According to Buchner the fermentative activity of yeast-cell juice is not due to the presence of living yeast cells, or to the action of living yeast protoplasm, but it is caused by a soluble enzyme.
