COLUMN A COLUMN B
A)
Ordinary companion cells i) appear well suited for taking up solutes
via cytoplasmic connections numerous plasmodesmata connecting them to bundle
sheath cells. Its having numerous small vacuoles, as well as poorly developed
thylakoids.
B)
Transfer cells ii) have chloroplasts with
well-developed thylakoids and a cell wall
with a smooth inner surface. The number of plasmodesmata connecting ordinary
companion cells to surrounding cells.
C) Intermediary cells iii) the development of fingerlike wall in growths, particularly on the cell Walls. These wall ingrowths greatly increase the surface area of the transfer cell’s plasma membrane, few plasmodesmata connect this type of companion cell to any of the surrounding cells except its own sieve element.
