Mass Flow Hypothesis

Question 1

Mass flow hypothesis

Answer 1

Translocation occurs due to pressure gradients

Question 2

1

Answer 2

Assimulates are loaded at the source into sieve tube elements from companion cells, decreasing the water potential in sieve tube elements

Question 3

2

Answer 3

Water enters the sieve tube elements from the xylem through osmosis, increasing hydrostatic pressure in the sieve tube elements

Question 4

3

Answer 4

Assimulates are removed from the sieve tube elements at the sink, increasing the water potential in sieve tube elements at the sink

Question 5

4

Answer 5

Water leaves the phloem by osmosis, decreasing the hydrostatic pressure at the sink, creating a pressure gradient, pushing assimulates from the source to the sink
