The only logical answer would be C. Unicellular, but the answers seem to be all wrong.
The greater the surface area of a cell, the faster the cell can transport materials across its membrane because there is more area to absorb/excrete materials. We also want the surface area much higher than the volume of a cell. the more volume a cell has the slower the transport of diffusion will be. If the cell is smaller because it has a higher surface area than it does volume. Because of this larger SA:V ratio, smaller cells will transport materials faster.
Answer: chlorophyll
Explanation: it has certain cells that are light-sensitive and capture that solar energy
Answer:
Because of evolutionary traits based on the environment.
Explanation: This is probably because they live in a similar environment, so they both evolved to have similar adaptations to make them excel in that specific enviroment
