Question

Dye injected into a plant cell might be able to enter an adjacent cell through______________
A. Microtubule
B. Microfilament
C. Plasmodesmata
D. Tight junction

Answer 1

Hint: Plants have evolved and developed various ways in which they can contact and transfer certain signals and materials to the neighboring cells easily. The dye injected will also travel to adjacent cells via these bridges or ways the plant cells have developed.

Complete answer:
As we know that the plant cells are in contact with each other and they all have cell walls in such a way that the materials inside one cell does not get mixed with the materials of the other cells. But what if when the cell wants to convey a signal or message to another cell?
They cannot do so as the cells are not in contact with each other. So, to overcome this the plants have developed a way in which the signals and materials can be transferred between the cells. The cell wall of the cells has very small pores which are known as the plasmodesmata, they act like a bridge between the two cells. So, if we inject ink into the cell then it will get transferred to the other cell via these pores called plasmodesmata.
Talking about the other options which are microtubule and microfilaments do not play any part in the transfer of any kind of material between the cells and the tight junctions are present in order to prevent any leakage between the two cells.

Therefore, the correct answer is Option C.

Note:
The microtubules and microfilaments are structures which are made up of protein and they are present in the cell wall. The function of these structures is to provide the strength and stability to the cell wall and prevent it from collapsing.
