... the roots and to proceed into them. They proceed into the cyanobacterial zone They now have to join the cortical cyanobacterial zone (inaccurately called 'algal zone') situated in the cortex (under the periderm), where they can become a cyanobiont. To do this, they must cross between or though cells ...
