Duckweed is more cold tolerant than other aquatic vascular plants. In the future studies should apply the problems that I have Hucks adolscent essay before. Although the average number of living duckweed did result to be higher when at room temperature, the difference was not significant enough to be conclusive.

Duckweed consists of 1 to 3 fronds, or an oval shaped leave—like structure Wedge and Burris Duckweed thrives off nutrients and grows best when the water contains higher levels of nitrogen and phosphate Wedge and Burris Small amounts of duckweed will not harm a water source, but large amounts will stop the sunlight from entering the water.

According to Appenrothwhen duckweed is place into lower or higher temperatures, the turion-inducing factor needs proper phosphate levels. Duckweed is a very tiny pale green, seed bearing plant Wang and Messing We generated this hypothesis due based on the fact that duckweed needs sunlight to gain the nutrients it needs to survive, and warmer climates commonly have more sunlight to help the growth and reproduction.

Thus, duckweed has a high range of survival under different temperature, but requires the appropriate elements. Without being able to use this adaptation, the duckweed will not be able to survive under certain temperatures.

Therefore, when we placed the duckweed under the florescent light treatments, the water may not have contained the correct amount of phosphate causing the duckweed to not be able to form into turion.

Each beaker was labeled with different colored tape to differentiate the beakers. In addition to those corrections, the results could have been broader if the study had a below room temperature treatment.

This is one of the best ways of spreading duckweed and would be done mostly in warmer areas where the bird and duck populations are the highest. Due to the amount of intercellular air space becoming less and starch increases the density of the tissue, the duckweed is able to sink to the base of the water where the organism is still able to live even if the surface of the water freezes Wang and Messing If we had more time to conduct the experiment, we could have had the duckweed under the treatments for a longer period of time, which would have given us more precise and accurate answers.

This can cause oxygen depletion, which can harm fish and submerged plants Wang and Messing This is an evolved adaption that duckweed has formed to be able to survive in several conditions.

There are conditions such as seasonal temperature change that can result in a morphological alteration to another form, called turions Wang and Messing Community Hospital North's pastoral relations department is committed to providing support services to patients, families and hospital staff, with respect to their own needs and traditions.
