Evidence against mass flow Flashcards
1
Q
The rate of translocation of different organic substances was measured and the results showed that amino acids appeared to travel more slowly than
what does this suggest
A
sucrose
The mass flow hypothesis states should be flowing at the same rate
2
Q
Some scientists have conducted experiments that detected different substances (within the same sieve element) moving in …. directions
what does this suggest
A
same
The mass flow hypothesis states everything should be flowing in one direction
3
Q
It has been suggested that some sieve tubes translocate at different
what dos this suggest
A
times
The mass flow hypothesis states that nearly all sieve tubes should be involved in translocation at the same time as they are all connected to the same leaves
