Germination and Productivity

LAB 5

The purpose of this lab is to prove right or wrong if can plants germinate in the dark? By using data from 4 different groups of people who planted radish seed in 4 36*36 trays which have been placed 2 on the dark and 2 on the light.

.    What was our control for this experiment?

When the experiment of germination y productivity was carried out in the dark with radish seeds at the same time a control experiment with radish seeds was placed on the sunlight. The same amount of time, seed, and dirt was selected for the experiment and the control with the difference of places.

.    What is the percent of germination for the light treatment? For the dark treatment?

Light treatment, percent germination

36*69 = 69/144 * 100 = 0.479 * 100 = 47.9% = 48%

Dark treatment, percent germination

50/144*100=34.7% = 35%

    

.    Difference in appearance in the dark treatment and the light treatment

The plants in the dark treatment had a light-healthy green looking while the plants in the dark treatment looked like fall-yellowish. The two treatments had good-looking plants with color differences; the light treatment had some brownish plants, but looking to the overall big picture the green plants look more alive than the yellow ones.

.    If there was growth in the dark treatment plants, explain why that growth may have taken place.

The plants in the dark treatment grew because seeds do not need to photosynthesis to germinate. The embryo inside the seed use the energy stored to germinate and when leaves are up the chloroplasts in it needs the sunlight to do photosynthesis and continue to grow.

   .    Dark treatment

Weight before dry 8.9g

Weight after dry 1.9 g

Loss 7g

Duration 5min

Temperature 400F 

 NPP+R=GPP--1.9g+8.9g= 10.8g

.    Light Treatment

Weight before dry 11.4g

Weight after fry 2.0g

Loss 9.4g

Duration 7min

Temperature 400F

NPP+R=GPP--2.0+11.4 = 13.4g

Conclusion

After obtaining the results from the four groups and the light and dark treatments it is possible to say that the hypothesis is proven right, seeds can germinate without sunlight because of the food stored inside the seed. Also, the results showed that plants that received sunlight grow healthy and good looking while the one that have low sunlight access grow weak, slower, and yellowish.
