Question

Dye injected into a plant cell might be able to enter an adjacent cell through a: a. plasmodesmata b. gap junction c. desmosome d. tight junction
Options
A plasmodesmata
Correct Answer
B gap junction
C desmosome
D tight junction
Correct Answer

Option A is the correct answer.

Detailed Explanation

Plasmodesmata are channels that traverse the cell walls of adjacent plant cells, connecting their cytoplasm. They allow for the direct transport of water, small molecules, and even some proteins and RNA between cells. Gap junctions serve a similar function in animal cells, but the question specifies a plant cell.

Hint

Think of the 'plasma' connection in plants – these are tiny pores in the cell wall connecting cells.
