1/ Name the key enzyme in the photorespiration of plants
2/ biological membranes are effective insulators preventingingress and egress of cytoplasmic solutes. How, then, do cellsacquire solutes?
3/ Name the transporter that is the principal source of theenergy gradient that co-transporters use to move solutes into orout of the plant cell.
4/ Fritz Went developed the bioassay. Explain what a bioassayaims to do.
5/ define an auxin. Are auxins related by chemical structureor by another feature?
6/ How are the actions of auxin and gibberellin at the levelof the gene fundamentally similar?
7/ what is expansin and how does it affect plant growth. Does"growth" of the wall require a living protoplast?
