Describe, using named examples and annotated diagrams where appropriate, membrane-bound nucleus and organelles within eukaryotes cells; explain evolutionary advantages of intracellular compartmentalization.

Living cells are the functional biological building blocks of animals. They come together to form complex organic tissues, organs, and whole bodies, as well as some of these organisms themselves existing in a unicellular form. Cells vary in size and dimension, with Eukaryotes ranging from 1x10-3m to 1x10-4m in length, whilst the smaller and less structurally complex Prokaryotes exist between measurements of 1x10-4m to 1x10-7m in length. This size is contained by the cell membrane; providing surface area, whilst the three-dimensional formations offer volume to the cell, which comes from the structural sum of all constituents present in the cytoplasm.

Cells have evolved; they are small in order to benefit from a large surface area to volume ratio. An increased surface area is very advantageous as it allows more sites for protein carriers to transport nutrients into the cell, as well as encouraging more biochemical reactions on the surface, and across the membrane. With both Eukaryotes and Prokaryotes having ability to transport multiple nutrients and molecules into the cell, a range of reactions can take place within these cells. All the vital catalysts, reactants and reagents required to make use of these transported substances are in the cytoplasm of both types of…
