Why is diffusion insufficient for transporting raw materials and energy to all parts of a large, com

Q: What is the correct answer for CBSE10?

The correct answer is A. In large, complex multi-cellular organisms like plants, the distances between organs (e.g., roots and leaves) are too great for simple diffusion to effectively transport raw materials and energy to all cells within a reasonable timeframe. This necessitates specialized transport systems like xylem and phloem.

This necessitates specialized transport systems like xylem and phloem.

Q: What are the options for this CBSE10 question?

A. Diffusion is too slow over long distances. · B. Plants do not produce enough energy for diffusion. · C. Plant cells are too tightly packed for diffusion. · D. Diffusion only works for gases, not liquids.
