bound organelles. These organelles support the many varied activities that a cell is required to carry

out, but also add to the complexity of the intracellular environment. There has recently been an

upsurge in the interest around constructing artificial cells, or cell like materials for pharmacological

research or possibly even medical treatments.

Keeping in mind the relationship between structure and function, discuss the potential uses of

artificial cells and/or cell like materials and whether you consider them to be a good substitute for the

natural versions.
