<span>The cells all have different qualities.
A plant cell will have a cell wall (the others don't have these) and so it will be kept in a rigid shape, unlike the others which are free to be blobby. Inside a plant cell, there is also a vacuole containing cell sap. The others don't have this. Plant cells also have chloroplasts, which look similar to mitochondria on a diagram. Chloroplasts contain chlorophyll, and this is used for photosynthesis. </span><span>

Answer:
Scientists should sent a robot and observe the light penetration in the ocean water.
Explanation:
Robots in modern day have become a source of experiments for scientists. Many scientists believe that sending a robot is a better way for research as they can have different observation at different time for a certain period before making a final remark. The robots should be sent in ocean water and observations should be recorded on graph. These observations should be made in different timings to make the research more realistic.
So the area is 2x3 cm with 68 paramecia.
Not sure if this is the best way to do it, but I’d do 68/2*3 (68 divided by (2 times 3))
So first 2*3 is 6cm.
Now you’re trying to find paramecia/cm2. You are trying to find a unit rate. That is a value over one.
Then because there are 68p and 6cm, to find the unit rate, you’d do 68/6.
Now you have your unit rate, which is 11.3 repeating, or 11 1/3 as a fraction.
That would be 11.3 (11 1/3) paramecia per cm2
also I’m not 100% sure if this is correct, just wanted to help, so no guarantees
