Question
Plasmodesmata are found between A. Sieve tube cells. B. Companion cells. C. Vessel elements. D. Tracheid E. Meristematic cells. What keeps the ventricles from contracting at the same time as the atria? A. Nerves from the brain conduct separate signals to the atria and ventricles. B. The atria and ventricular pacemakers touch off contractions at different times. C. The sends separate node sends separate signals to the atria and ventricles. D. The atrioventricular node delays the signal from the sinoatrial node. E. A and B only.Explanation / Answer
Plasmodesmata are microscopic channel between adjacent cells in plant enbaling the transport and communication between them.
They transport mineral, water and other substances from one cell to other.
Meristmetics cells are dividing cells and for their division they require communication and transport of signals between them. For this purpose they have large number of plasmodesmata between them.
Plasmodesmata also present between compain cell and sieve tube element but neither between companion cells nor between sieve tube elements.
So here ans is option E.
Plasmodesmata are found between meristmetic cells.
