Duckweed is a stemless aquatic flowering plant . Lemencenae is a small free floating plant that grows on water surface.(clean flo) Where?
Being a large populated plant duckweed is knownto be found all over the world.The most common places/sites to find duckweed are in ponds . They may also be found in fringesof lakesand in backwaters and some sloughs that are cut off large rivers. They are not found in places such as Alaska, Antarctica and Egypt because they have extreme tempatures and weather conditions. Ecological niche: Light Intensity

Duckweed is hypothesized which means its amount of light received will alter its photosynthetic rate. Its is predicted by scientsists that that a lower intensity will lower the rate of growth in duckweed. The process in testing for this is dependant on two factors, abiotic and biotic. In study of Lemna minor , it is observed that the growth of duckweed does not only rely on the intensity of light, but also heavily depends on abiotic factors suh as tempature,wind water, and evn oxygen levels. Plants that typically receive more light will usually gain a higher rate per capita growth, whicjh means the higher the light intensity the more the duckweed will grow.

Hypothesis: To investigate if the growth of duckweed is affected by the lowering of light intensity Prediction: My prediction is that if the light intensity is decreased, the rate of capita growth of the duckweed will decrease.

osynthesis. Plants that receive more light are also predicted to reach their carrying capacity sooner because of...
