Final answer:
The extracellular matrix (ECM) does not assist in the movement of organelles within cells, as this is managed by the cytoskeleton and motor proteins inside the cell. Therefore, answer D is the correct choice.
Step-by-step explanation:
The extracellular matrix (ECM) in animals is involved in several key functions that are vital to tissue integrity and physiology. Notable functions include directing the migration of cells during development, supporting the structure within the animal, and facilitating the movement of nutrients.
However, one function that is not a role of the ECM is assisting in the movement of organelles within cells. Organelle movement is managed intracellularly, usually by the cytoskeleton and molecular motor proteins like kinesin and dynein rather than the ECM, which exists outside of cells.
The correct answer to the question, 'Which of the following is not a possible function of the extracellular matrix in animals?' is D. assist in the movement of organelles.
