Which statement about phloem transport is false?
It takes place in sieve tubes
It requires metabolic energy
A high pressure potential is maintained in the sieve tubes
At sinks, solutes are actively transported into sieve tube elements
The mycorrhizal relationship allows a plant’s roots to ??
increase the amount of soil than can be accessed for nutrients.
grow in nutrient-poor soils.
avoid direct interaction with the soil.
None of the above
Solution
1. At sinks, solutes are actively transported into sieve tube elements. (False)
Phloem is a vascular tissue in plants that actively transports synthesized food from the source
tissue ( photosynthetic) to sink tissue (non-photosynthetic). The sieve tube elements (STEs) are
the phloem tissue compartments which help in the transportation of food from source to sink.
Phloem transport requires metabolic energy and a high-pressure potential is maintained at the
sieve tubes.
2. Increase the amount of soil that can be accessed for nutrients
Mycorrhiza is the symbiotic relationship between fungi and the plant roots on which they
extensively grow. The network of fungal growth or mycorrhiza helps in increasing the surface
area of the roots so that they can access more amount of soil and take up nutrients essential for
plant growth..
