I need a concise answer to the syllabus question: State how strengthening tissues can be established in monocotyledons allowing perennial growth to occur. I understand secondary thickening I just find it hard to come up with memorable concise points!! Any help would be musch appreciated!

  Reply | Contact I'm assuming that this is a short question and not a long one and that you've got about three minutes to answer it. It's not very well worded, is it? Err...haven't thought about this for a while. Well, there are the main points - the lack of cambium in monocots, the arrangement and increased number of vascular bundles and the associated support tissue. So you could say that stem strengthening occurs by the many vascular bundles being scattered, rather than in a ring (as in dicots), with the bundles being surrounded by extensive fibres (sclerenchyma) which are used for support. You could add that the absence of hard wood, combined with often vertical veining, allows for greater stem flexibility in strong winds. A nice quote from Botany for Gardeners: 'Trunk thickening in large monocots, such as palms, simply results from repeated formation of the scattered vascular bundle pattern, formed during a process called diffuse secondary growth'. I hope that helps and doesn't make it worse ;-) Digger, help with revision is allowed!

  Reply | Contact Thanks Miranda!! very helpfull. I actually meant to say Dicots but I managed to create a couple of paragraphs for that myself and your answer helped me with the next question!! I'm stull unsure that all of this information is actually going to stay in my head but I haven't got time to worry about it!! Stop telling people off digger - how are you meant to learn if you don't ask questions about things you are unsure of and I'm hardly sitting my exam whilst on the RHS website!!!! hahaha! ;o)
