Transport in Pl...

Which of the following is not a function of transpiration?

Transpiration is influenced by

The initial stage of water absorption by root cells is by

What would be the effect if a freshly cut end of a plant is put in eosin solution?

Osmosis is the movement of

In the cross section of a plant stem below, which structures transport water to the leaves?

Root pressure is retarded or become absent in

Study the following table showing the components of water potential of four cells of an actively transpiring monocot plant.

Cell	Osmotic potential	Pressure potential
	(MPa)	(MPa)
A	-0.9	0.5
B	-0.8	0.6
C	-0.6	0.1
D	-0.7	0.4

Identify the four cells as root hair, general cortical cell, passage cell, and pericycle cells of young root respectively (assume symplast flow).

Living cells placed in an isotonic solution (0.9% saline) retain their size and shape. This is based on the concept of 

Study the following table showing the components of water potential of four cells of an actively transpiring plant.

Cell	Solute potential (MPa)	Pressure potential (MPa)
A	- 0.68	0.42
B	- 0.75	0.36
C	- 0.83	0.47
D	- 0.57	0.29

Identify the four cells as root hair, cortical cell, endodermal cell (lacking Casparian strips) and pericycle cell respectively in the young root (assuming symplastic water flow through them).
