Q1. You are required to design a carbon-based, eukaryotic, unicellular organism that contains membrane-bound organelles that match those on Earth. Describe specific structures and components that you would include in the cell wall, plasma membrane and internal cell membranes of your cell that would assist the cell's survival in the low temperatures and high pressure experienced on Kepler-28d. Specfically, mention what can be added to internal cell membranes, structure wise and components (200 words maximum)

- Q1. You are required to design a carbon-based, eukaryotic, unicellular organism that contains membrane-bound organelles that match those on Earth. Describe specific structures and components that you would include in the cell wall, plasma membrane and internal cell membranes of your cell that would assist the cell's survival in the low temperatures and high pressure experienced on Kepler-28d. (200 words maximum) Answer here: Q2. It is critical that your cell contains the capacity to transport and traffic cellular components both intracellularly and extracellularly. To facilitate this you will need to develop an endomembrane system. Outline the function of the endomembrane system, including which organelles will be included within your endomembrane system.
