If you want a raster or vector file, then have look at the figure exporting command saveas.
If you want to save it as a MATLAB .fig, then use savefig.

Try this:
plot( cytoplasm1(:,2), cytoplasm1(:,1), 'g-', 'LineWidth', 1);
saveas(gcf,'my_wonderful_cytoplasm_image.png')

It is saved in a folder: your current folder . If you want to put it in a subfolder of the current directory, you can use:
saveas(gcf,'my_subfolder\my_wonderful_cytoplasm_image.png')
or change the current folder .

I would not use the cd function. I'd use fullfile() as per the FAQ.
fullFileName = fullfile(folder, baseFileName);
The FAQ explains further why this is the recommendation: http://matlab.wikia.com/wiki/FAQ#Where_did_my_file_go.3F_The_risks_of_using_the_cd_function.

Sure. I was not trying to imply that they should change the Current Folder for just that one operation, but I have noticed that some users do not seem to realize that the Current Folder can be changed at all, yet their work would be much simpler if they simply changed to a more convenient directory.
