Question

Can you please check over thiss for me...Thank youuu...

Note: Elodea is a fresh water plant.

a) Elodea cells normally contain 1% salt and 99% water.
b) Tap water contains 1% salt and 99% water.
c) Salt water contains 6% salt and 94% water.
d) Salt water has a higher concentration of salt than fresh water or Elodea cells.

Answer the following questions using the information above about the cell in salt water:

1) What is the percentage of water outside the cell at the start?- 94
2) What is the percentage of water inside the cell at the start? -99
3) How do the percentages compare? - the percentage of water inside the cell is higher than that of outside the cell
4) When will water move across the cells membrane? -during osmosis?
5) WOuld the cell shape change once it was placed in the tap water? -yes because the cell was trying to equal the concentration of water and salt inside and outside of it...

is all of this correct? if not, can you please correct my answers

Answer 1

1) Incorrect - assuming the question refers to Elodea that is sitting in tap water
2)Correct
3) Correct logic based on your answer for #1, but incorrect since #1 is wrong
4) Correct, but this might be asking whether water moves across the membrane when Elodea is in freshwater, when its in saltwater, or both.
5) Correct logic given your answer to #1, but incorrect


Here's the point of this exercise:

Plasmolysis is a form of osmosis where there is a loss of water
from a plant. Specifically, when elodea is palced in saltwater, the water moves from where it is more concentrated through the cell membrane to the outside where there is a lower concentration of water. .

Answer 2

I'm just surmising but wouldn't the cell return to its original size and shape once back in tap water due to reverse osmosis (#5)? If so, you should probably say that. Also, your answers should be written with the % sign, not a minus or negative sign, right? Too, for #3, I'd say the percentage of water inside the cell was 5% higher than...

Answer 3

a) sounds severe to me. Google it. b)faucet water has much less salt than a million%, c) sea water has the comparable % by way of fact the salt in our blood, and additionally Ringers answer. Salt water is only 0.9% salt, that's below a million%. (in maximum seas (the lifeless sea has a lots greater % of salt.) d) particular (additionally elodea is a clean water, greater plant, this isn't any longer a marine (salt water plant.) a million) what form of water, clean water or sea water? 2) this relies upon on the particular cellular form. and the cellular's factors. (e.g. proteins, organelles (like the nucleus, mitochondria, ribosomes, cellular membranes, cytosol ptoteins, carbohydrates, nucleic acids, lipids, etc. that are no longer water consistent with-se). 3) Osmosis might tend to equalise the possibilities interior and out. yet maximum cells use skill to pump out water and/or mineral ions.which will replace the %'s. 4) this is often superb yet some cellular types have unusual possibilities of NaCl of their cytoplasm. Marine fish often upward thrust to the exterior in rainstorms by way of fact the exterior salt water is diluted. They do it to kill floor parasites by way of fact those organisms can't tolerate the low saline water and water rushes in by employing means of osmosis, to dilute the better saline concentrtion in those cells They swell and pa. checklist.
