Explanation / Answer

5a. The answer is b for fungi. They do not succumb to surrounding high osmotic pressure. Most bacteria do. That's why they are fought by preserving in marmalades and brine (high glucose or salt) and cured meats and ham (high sugar, salt, honey, etc.) 5b. The best answer for animals is d. The lack of a cell wall like the one in plant cells is the most important factor in their intolerance to unaccostumed high osmotic pressure.
