High School Department General Science How Does Phosphate Affect the Growth of Aquatic Plants? (A Problem Proposal) I. Introduction Aquatic plants are an important component of lake systems. These plants may be totally submerged beneath the lake surface‚ floating‚ or growing along the shoreline. They provide food and shelter for bugs‚ fish and other organisms‚ prevent shoreline erosion‚ filter pollutants from adjacent shoreline activities‚ and

to be rather slow as very little growth could be observed. After the several days of being under the scorching sun the leaves of the tomato plants started to dry up and would fall off at the very touch of it. More water had to be added to them to further hydrate the plants. It was only after around 30 days that a concrete growth could be observed. The plants grew to a reasonable height and needed to be attached to a bamboo stick so as to remain stable. The growths of the tomatoes themselves were tremendous

by plants is not only dependent on photosynthesis‚ but also cellular respiration (Reddy et al. 1970). Cellular respiration‚ an array of metabolic processes‚ in plants is the oxidation of the chemical energy from acquired nutrients into energy in the form of ATP or adenosine triphosphate. In a germinating pea‚ which respires‚ the mitochondria provides cellular ATP‚ this is possible because it is utilizing stored nutrients (Stupnikova et al. 2006) In order to determine if a non-germinating pea respires

Affect Plant Growth - Does Music Affect Plant Growth - Aim: To see if playing music to plants affects their growth Background: Over the years there have been many theories that talking to plants and playing music to them has the effect of increasing their growth. If this fact is true it would have extremely beneficial affects to the agricultural and farming industries and by extension the general populace. Internet research however suggests that music has no effect on the plants themselves

An experiment was carried out at the Horticulture Farm‚ Bangladesh Agricultural University‚ Mymensingh during 1998-99 growing season to study the effect of nitrogen and plant spacing on the growth and yield of potato (var. Diamant). Different nitrogen levels viz. 0‚ 127.0‚ 190.5 and 254.0 kg N/ha significantly influenced plant height‚ foliage coverage‚ number of main stem per hill‚ days required for 80% maturity of the crop‚ fresh weight of haulm (g/hill)‚ number of tubers per hill‚ weight of tubers

Savannah Booker‚ Dubie Dubin Research Plan Problem: What is the effect of gasoline fumes on bean plant growth? Hypothesis: If the bean plants are exposed in the presence of gasoline fumes for a longer period of time‚ then the plants will die more quickly. Procedures: 1. Place ten bean plants in each of five Rubbermaid clear plastic containers. 2. Let the bean plants sit for one week without being manipulated. 3. Leave the first container alone without manipulation.

the Plant the Longest? Daniel Rivera Alfonso Pineda Mrs. Fraijo AP Biology 10 June 2012 Abstract: In this experiment‚ 8 plants will be tested. Each except one plant (which will be the control group) will receive a certain amount of water starting at 0 teaspoons of water. Each plant will receive 1 more teaspoon than the previous cup‚ so it would be increasing. For example‚ cup 4 will have 4 teaspoons of water and cup 3 would have 3. The data recorded will be the length the plant grows

Plants‚ also called green plants (Viridiplantae in Latin)‚ are living organisms of the kingdom Plantae including such multicellular groups as flowering plants‚ conifers‚ ferns and mosses‚ as well as‚ depending on definition‚ the green algae‚ but not red or brown seaweeds like kelp‚ nor fungi or bacteria. Green plants have cell walls with cellulose and characteristically obtain most of their energy from sunlight via photosynthesis using chlorophyll contained in chloroplasts‚ which gives them their

rain effects the growth or germination of plants. In this experiment we are testing if acid rain effects the growth or germination of common pea seeds. The independent variable in this experiment is the replica of the acid rain (or the PH level)‚ while the dependent variable is the growth/and or germination of the pea seeds. This is a common problem in our environment today as rain continually gets more acidic. Our hypotheses in this experiment were that the growth of the pea seeds in the experimental
