Dill Weed By Emily Potter, Joshua Trevino, Rowan Dickey, Jeremy Eden

Introduction Our research question is: does dill grow better in the light or in the dark? Our hypothesis was: we think the dill will grow better in the light because a plant can’t survive with out light. Our hypothesis was proved wrong when the dark plant grew longer than the light plant. But it was more healthy in the light.

Back ground information Dill weed or Anethum graveolens Photosynthesis occurs in the chloroplasts of the plant cell of the dill weed. seed flower stem leaves Below here would be the roots.

Back ground information part two Carvone is a kind of organic compound found in dill that helps give off its unique flavor, it functions as insecticide. This compound helps the plant survive by keeping bugs from eating it. Yes carvone is an adaptation. Did you know???? In Europe and Asia people consume over 9 pounds of dill per year. dill is often used as a spice in soups or boiling potatoes.

General Plant Information The three factors that can effect the growth of the plant are sunlight, water, and carbon dioxide.

General Plant Information Part two The function of photosynthesis is to turn carbon dioxide into energy for the plant. The chemical reaction In photosynthesis is when carbon is turned into sugars or energy for the plant. The chloroplasts are responsible for photosynthesis in the plant cell. The xylem is important for photosynthesis because it transports water, and you need water for photosynthesis to happen.

Project design 1.We put three dill seeds in two cups 2.We placed one cup in the light and one in the dark 3.We observed and recorded data from how they were growing 4.We watered them when needed 5.We measured how tall they grew each day

data

Other information The plant grew upward because the light was above it this process is called phototropism. The roots of our plant grew downward this process is called geotropism. one interesting thing we saw was that the plant in the dark grew longer than the plant in the light, a theory our group had was that maybe it was trying to get to the light.

Summery In the end the dark plant died because it didn’t have sunlight, and you need sunlight for photosynthesis. So our data ended up supporting our hypothesis because the light plant did grow taller than the dark plant. Some questions we had during the investigation were, does water help if the plant is dead? And, would the light plant grow even taller if we plant it outside? Or, did the dark plant grow taller because it wanted to reach the light?
