The older fronds on the plant will develop little buds. It was supposed to be a simple investigation, honestly. The fruit contains several ribbed seeds which are resistant to prolonged desiccation and quickly germinate in favourable conditions.

Duckweed is a tiny aquatic flowering plant that drifts in large colonies in still water. In all four genea each mother frond produces a considerable number of daughter fronds during its lifetime.

Duckweeds now appear to have the potential to be harnessed as a commercial crop for a number of purposes. However, due to the plant's rapid and dense growth characteristics, some jurisdictions consider hemp a prohibited and noxious weed, much like Scotch Broom.

At the present time it appears that potentially the application of scientific research could maintain the momentum for increased food production to support an increasing world population, but it is rather obvious that if this is to occur it must be without increased pollution, and with limited increases in the need for water and fertiliser and therefore also fossil fuel.

Duckweed, being a living thing, is constructed of many cells. Nitrogen requirements Duckweeds appear to be able to use a number of nitrogenous compounds either on their own or through the activities of associated plant and animal species.

Little work has been done to find the best balance of nutrients to provide maximum growth of duckweed. Stomata are on the upper side in all four genea.

Duckweed mats often abound in slow moving backwaters down-stream from sewage works. The senescence-rejuvenation cycle is increased by high temperatures through a decrease in individual frond life span but there is a concomitant increase in daughter frond production so that the biomass of fronds produced in a shorter life span is the same.

Differentiation and identification is difficult and is perhaps irrelevant to the discussion. Trace elements are often deficient in the major feed available to the livestock of small resource poor farmers. We would like to make a wildlife habitat on the back side of our property.
