Specialised Roots: Quiz
Answer the following questions based on the results from the graph by selecting the statement you think is correct...
In infected roots, P uptake is greatest
at the root tip
2-3 cm behind the tip
in the mycorrhizal zone
try again
No, look at the graph and try again!
No, as in the uninfected root it is greater here than at the tip but the highest uptake is in the mycorrhizal zone.
Yes, uptake is greatly improved in the mycorrhizal zone (red areas on the top graph).
Well done, you answered correctly. Use the 'next' button to proceed.
This graph shows the uptake of phosphate for non-mycorrhizal roots. Trace the mouse over the graph for an explanation of the results.
The graph shows the uptake of phosphate for both mycorrhizal and non-mycorrhizal roots. Trace the mouse over the graph for an explanation of the results.
