Question

Plasmodesmata are cell-cell interaction structures found in plants. Plasmodesmata contain a dense central structure called desmotubule, which is derived from ________.

Answer 1

Plasmodesmata are cell-cell interaction structures found in plants. They contain a dense central structure called desmotubule, which is derived from the endoplasmic reticulum (ER). Plasmodesmata enable transport of materials, such as water and nutrients, from cell to cell in plants.

Step-by-step explanation:

Plasmodesmata are cell-cell interaction structures found in plants. They contain a dense central structure called desmotubule, which is derived from the endoplasmic reticulum (ER).

Plasmodesmata are numerous channels that pass between the cell walls of adjacent plant cells, connecting their cytoplasm. These channels allow materials, such as water and nutrients, to be transported from cell to cell.

For example, when a plant needs to transport sugars from its leaves to its roots, plasmodesmata facilitate the movement of these sugars through the connected cells.
