What is translocation?
What is a source?
What is a sink?
Complete the sentences:
MASS FLOW HYPOTHESIS (1/3)
Active transport loads _________ into sieve tubes at the ________. This lowers the Ψ inside sieve tubes so water enters sieve tubes by ________ from the _______ and __________ cells. This creates a high _________ inside the sieve tube at the source end of the phloem
Complete the sentences:
MASS FLOW HYPOTHESIS (2/3)
Solutes are removed from the ____________. This usually happens by __________ (passive)
This increases Ψ inside sieve tubes so water leaves the tubes by ___________
Complete the sentences:
MASS FLOW HYPOTHESIS (3/3)
This results in a _________ gradient from the source to the sink. This gradient pushes ________ along sieve tubes. The higher the concentration of sucrose at the source, the _________ the rate of translocation.
TRUE OR FALSE:
Translocation is a passive process
Describe the process of active loading
