Final answer:
The percentage of water in Elodea cells is typically high, around 90% to 95%, but the exact value is not provided and should be verified with a biology textbook or specific class resources.
Step-by-step explanation:
The question pertains to the percentage of water in Elodea cells. While the specific percentage is not provided in the reference information, it is widely understood in biology that plant cells have a high water content. Typically, plant cells can be anywhere from 70% to 95% water depending on the type of plant and environmental conditions. However, without specific information regarding Elodea cells, we cannot determine a definitive percentage. Therefore, any of the given options could potentially be correct, but for most plant cells, a high percentage like 90% or even 95% is more common. Students should refer to their biology textbooks or specific lecture notes to find the precise value for Elodea cells.
