In higher animals' bodies, tissue fluid is isotonic contrary to plants because in plant cells:
Correct answer: D. Cell wall creates resistance in water uptake
- A. Cell membrane creates resistance in water uptake
- B. Plastids create resistance in water uptake
- C. Chlorophyll creates resistance in water uptake
- D. Cell wall creates resistance in water uptake
Explanation
In-plant cells, there is an additional potential exerted by the cell wall from the outside that increases the overall osmotic potential inside. This effect of pressure potential in plant cells is not seen in animal cells due to the absence of cell walls, even though the solute potential inside and outside of the cells are not equal, still, osmotic potentials are equal.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
