Plant growth and flowering are strongly controlled by root and stem signal chemicals.Which of the following cell connection transports these molecules between adjacent cells?

Question

Quizplus · Accepted Answer

Plasmodesmata are channels that connect adjacent plant cells, allowing for the transport of molecules such as root and stem signal chemicals. This type of cell connection is specific to plants and is crucial for communication between different parts of the plant. Gap junctions, anchoring junctions, and tight junctions are found in animal cells and serve different functions. The cell wall, while present in all plant cells, does not play a direct role in the transport of molecules between adjacent cells.
