Title: What challenges does paramecium face in a specific environment? Post by: Krystal209 on Mar 28, 2023 A paramecium is a single celled organism that lives in freshwater. If the cytoplasm of the paramecium is composed mainly of saltwater, what challenges does the paramecium face in this environment?
Title: Re: What challenges does paramecium face in a specific environment? Post by: bio_man on Mar 28, 2023 In this specific scenario, the paramecium would prefer to live in a solution whose percentage of salt inside equals that amount outside so that it lives in a state of homeostasis. If the salt concentration outside exceeds that inside (hypertonic solution), it will lose water, thus shrinking its volume. If the concentration of salt outside is less than inside (hypotonic solution), water will tend to diffuse into the cell, causing it to increase in volume. Thus, the paramecium must always seek an isotonic solution.
