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)
