different concentrations of salt water effect plants. The test that will be performed will prove which concentration will have the worst effect. The hypothesis is that by measuring the plants growth each day‚ the largest concentration of salt will harm the plants the most. First‚ the plants were purchased and the water was prepared with the salt concentrations. Second‚ the plants were watered each day with the different concentrations of salt. Third‚ the plants’ growth were observed and recorded each

affect plant growth could be an interesting experiment. Our experiment consisted of different levels of Windex mixed with water and given to Brassica Rapa plants in order to grow. Are results showed that Windex barely had an effect on the plant growth and the plants showed steady increase in growth. In conclusion‚ our experiment did not assure that Windex add a boost in plant growth but we did find that small‚ insignificant amounts of Windex mixed with water were able to ingested by the plants.

TOMATO PLANT 1) Seed: Tomato seeds are small‚ flat and disk shaped and about 1/8 inch wide. They contain two energy storage organs called cotyledons and an embryo encased in a hard outer shell called the seed coat. The seed is the dormant or resting stage of the plant life cycle. When young tomato plants are damaged‚ they tend to go into a dormant‚ survival stage in which plant growth is delayed for a while. Frost damage is something to look out for when planting tomatoes early on in the season

Plant Adaptation Investigation Observations Samples of plants were obtained during the campus tour. In order survive in the harsh climate of deserts‚ plants must adapt in function‚ reproduction‚ support‚ and defense. Although plants on campus are watered frequently‚ they live in a mostly xeric environment. Three types of cacti were observed: organ pipe‚ prickly pear‚ and saguaro. The organ pipe contains no leaves and has narrow stems that carry out photosynthesis and store water. Neither the

The uses of plants in developing and producing vaccines For thousands of years‚ society has been brought to the brink of disaster thanks to the spread of resilient diseases and the plague of hardy viruses. However‚ humans have been aware for just as long of medicinal defence mechanisms against these ailments. The ancient Egyptians and Romans‚ as well as the primitive islander and Aboriginal communities‚ knew that certain herbaceous matter could help heal the wounded and sick. In more recent times

An oil spill can be defined as an accidental or deliberate dumping of oil or petroleum products into the ocean and its coastal waters‚ bays‚ and harbors‚ or onto land‚ or into rivers or lakes (Holum 1977). Between one and ten million metric tons (one metric ton is 1000 kilograms) of oil are put into the oceans every year. The oil is released‚ most often‚ in small yet consistent doses from tankers‚ industry‚ or on shore waste disposal (Boesh‚ Hersher‚ et al. 1974). Tanker spills cost the United
