To plot we use plot....to access a cell we use {}...what problem you have?

Most such things are possible.
How?
Difficult to say without knowing your data and what you expect the output to be.

You have multiple blobs so multiple boundaries, each of a different length so that's why they're in a cell array. You need to extract each boundary one at a time and plot it. See this snippet. Adapt as needed.
imshow(originalImage);
title('Outlines, from bwboundaries()', 'FontSize', captionFontSize);
axis image; % Make sure image is not artificially stretched because of screen's aspect ratio.
hold on;
boundaries = bwboundaries(binaryImage);
numberOfBoundaries = size(boundaries, 1);
for k = 1 : numberOfBoundaries
thisBoundary = boundaries{k};
plot(thisBoundary(:,2), thisBoundary(:,1), 'g', 'LineWidth', 2);
end
hold off;
