Fig. S1 TEM analysis of Nostoc punctiforme short/thin and long/thick PLS
(denoted by closed and open arrow, respectively). (a) Long/thick PLS observed
along with short/thin PLS in N. punctiforme, (b) Magnified image of a in the
reverse direction showing closely spaced long/thick PLS and short/thin PLS, (c)
Magnified image of b showing short/thin PLS; (d-e) N. Punctiforme cells showing
long/thick PLS along with short/thin PLS

Fig.S2 I-V graph of extracellular material (ECM) attached to the PLS (inset of
Fig. 3B). Horizontal noisy line represents non-conductive behaviour of ECM.

Fig.S3 Current map images of (a) short/thin and (b) long/thick PLS from N.
punctiforme grown under normal culture conditions, at +0.2V, (c) Current map
images of I-V spectra of short/thin PLS from N. punctiforme cells grown under
continuous light intensity, at +0.2V.
