Only Darkness Affect The Growth Of Duckweed
Title: How Does Both Only Light and Only Darkness Affect the Growth of Duckweed?
Introduction:
Question: How will all light or all darkness affect the growth of duckweed? If so, how drastic of change will it be?
Background: Duckweed, one of the fastest reproducing organisms on the planet. “The duckweeds (genus Lemna) and related genera of the duckweed family (Lemnaceae) are the smallest flowering plants known.” (USDA common duckweed) Duckweed, only about .3 mm in diameter, are found in almost all wetlands around the world. Duckweed is a decomposer, and is a prey of leeches, insects, snails, earthworms, and frogs. Although, duckweed does eat composed animals, such as water birds. One reason duckweed is studied by many scientists around the world, …show more content…
12 green buds on top, but many brown buds floating on the bottom.
10/11
Most of the brown buds have rose to the top, not much increase of green buds. Only about 1 inch of water has evaporated. 15 Buds
Stayed pretty much the same. Only difference was some of the green buds turned brown and sank to the bottom. No water has evaporated. 12 Buds
Most of the brown buds have rose to the top. Just a tad bit of water has evaporated.
13 buds
10/12
We decided to add water because most of it had evaporated. Not as many brown buds, but mostly green buds. The chain reaction is starting to occur. 19 buds
No change. 11 Buds.
Not much of a change. Just a lost of some water due to evaporation. 14 Buds.
10/13
Not much change. Bigger/more buds doesn’t look visible. The water is foggy. 23 Buds
Not much of a change. Just we caught the reproduction process in progress. A lot of small green buds surrounding one big green bud. 11 Buds
Completely brown on bottom, just a few green buds on the top. All of our living organisms died. 21 Buds.

Coming back after the weekend, all the water evaporated, and the green buds were resting at the bottom of the cup. Total of 29 …show more content…
The duckweed that was only affected by light, increased by 17 green buds. The duckweed that was affected by only darkness decreased by 3 of the buds. Which means, the big green buds that living duckweed is supposed to look like, turned brown and sank to the bottom of cup, being fully submerged in water. Last, the duckweed that was affected by both light and dark, doubled in amount of buds.
Evidence: By looking at the table, it shows the daily quantitative and qualitative data for a week. It shows that the duckweed with only light grew from 12 buds to 29 buds. Also, it shows the cup of darkness decreased from 12 to 9 buds. The table then shows that the cup of both light and dark doubled from 12 to 24 buds. The line graph shows this by, the cup of light and the cup of light and dark increasing, when the cup of only darkness decreases. Last, looking at the pictures show that increase and decrease from the different types of duckweed being
