      We are doing our biology A2 coursework and we need a bit of help on what we should include in the ‘background knowledge’ part. We can’t seem to find much information on the internet, and whatever we do find, its not relevant to be included in the discussion.

      we want to know about vesicles on the bladder wrack, why they are there and how they came to be there.

      any help would be very gratefully appreciated!!!

      many thanks

      I like this topic.
      Most of aquarium plant use C4 cycle (with monocots) or like C4 cycle (with flowerless). The vesicle structure of this special C4 plant are come from bundle seath cell when vein become unneed in water environment, now it is a chamber contain CO2.
      One more purpose of vesicle is to help the plant’s leaf alway float up in the water (not settle down to the bottom).

      Hey there,

      Just wondering whether and how I can link bladder numbers to abiotic factors such as tide, positioning on the shoreline, temperature, salinity etc. I’m trying to validate my biological knowledge about mucolige preventing pigment alteration in the heat and other bits to my personal investigation of bladder numbers. I wanted to know of all the possible, (likely and unlikely) abiotic and biotic factors which may alter the bladder numbers and their size/shape.

      thanks.

      Just wondering if the only advantage of having the airbladders was to allow the phototrophic frond to float nearer the surface of the water, or whether there were other advantages.. and even disadvantages. Im trying to link all the biological knowledge back to my personal investigation of hypothesizing that as you move to the sublittoral zone the f. vesiculosus that actually exist, will have more air bladders.

      cheers for all your help

      😀
