Transmission electron micrographs of (a) normal C. pyrenoidosa cells (b) C. pyrenoidosa incubated with washed A. fumigatus pellets (2.5 h) (c) C. pyrenoidosa incubated with A. fumigatus spent medium (2.5 h) (d) C. pyrenoidosa incubated with GlcNAc (2.5 h); CW denotes the cell wall of algal cells. The arrows show the formation of villi-like structures on the cell wall after incubation with A. fumigatus spent medium/GlcNAc. The images shown above are the representative images for each treatment selected out of multiple frames
