Hello Insani, maybe you are right, it would be nice if this group was more active. I don't know who is the admin. Anyway we could take the word of the day from this following site and develope the topic by starting from that word. Just h***e a look to this link: http://www.thefreedictionary.com/, the word of today is "phloem", the food-conducting tissue of vascular plants, consisting of sieve tubes, fibers, parenchyma, and sclereids. Synonyms: bast. Usage: "Girdling" a tree, or cutting through its phloem tubes, results in the starvation of the roots and, ultimately, the death of the tree. It is just a proposal if there is nobody as a admin in order to revive this group. H***e a nice day!!!
