properties that affect the growth rate of plants in different ways. These properties may be the wavelength of the music‚ its frequency or even its tempo. According to a study conducted by Margaret E. Collins and John E. K. Foreman‚ entitled The Effect of Sound on the growth rate of plants (2001)‚ plants growth is directly affected by sounds of varying frequencies. They observed that when plants are exposed to pure tones‚ it affects the growth of the plant. This was due to the transverse wave which

LEAVES BIODIVERSITY HOTSPOTS? A. ELIZABETH ARNOLD1 AND F. LUTZONI Department of Biology‚ Duke University‚ Durham‚ North Carolina 27708 USA Abstract. Fungal endophytes are found in asymptomatic photosynthetic tissues of all major lineages of land plants. The ubiquity of these cryptic symbionts is clear‚ but the scale of their diversity‚ host range‚ and geographic distributions are unknown. To explore the putative hyperdiversity of tropical leaf endophytes‚ we compared endophyte communities along

Research Project: The Effect of Calcium on Plant Growth Problem Statement What affect do various amounts (0 mg‚ 300 mg‚ 600 mg) of Calcium added to Vigna unguiculata (black eyed pea plants) once a week have on the overall growth (height‚ number of leaves‚ number of pods) over a 30 day period of time? Research Hypothesis If various amounts (0 mg‚ 300 mg‚ 600 mg) of Calcium are added to Vigna unguiculata (black eyed pea plants) once a week‚ then those plants receiving 300 mg of Calcium will have a

surface of water and mud. Algae were evolving at the water’s edge‚ and one group – probably the charophytes – gave rise to plants. Cooksonia‚ a simple branching plant a few centimeters tall‚ evolved by 430 million years ago. It took another 160 million years for the taller Psilophyton to evolve. Then the evolutionary pace picked up. It took only 60 million years for plants radiate from the swampy lowlands to high mountains and nearly all places in between. They did so through modifications in

Experimenting with Plant Growth Team Rocket Science Introduction: The purpose of the experiment was to establish whether the concentration of Schultz fertilizer that was added to the radish seeds effects the speed of growth during the six-week time frame of the study. The major variables with this study are proficient communications among the team‚ the seeds‚ soil‚ water concentration‚ fertilizer‚ light exposure‚ temperature of the room‚ consistency of following watering (watering the plant same time every

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

What pH Level Causes a Plant to Grow Best Alexis Chavez‚ Heather Nutt‚ Nguyen Phan Introduction We knew that water is normally stated as the best form of liquid to make sure plants grow as best as they can‚ but we wanted to know if causing the water to be more basic or more acidic would affect how the plant grew. Our hypothesis was that if the plant is treated with a pH of 12 then treated with another pH. Materials The materials used were three identical plants‚ that each had 4 sections that were

deforestation keeps on happening? I strongly believe that we need to stop deforestation before it is too late‚ or else we‚ humans‚ will suffer a lot from it. It has been told that forests are our world lungs. As many of us have known‚ every green plant can do photosynthesis‚ a process of producing oxygen from carbon dioxide. If deforestation keeps on happening‚ our oxygen supply will also deplete. That’s one thing I can guarantee. It means that we won’t have enough air to breathe with and it will

Science-104 Question: Does different types of water affect how high a plant will grow? Golden pothos‚ also known as devil’s ivy‚ is an ideal houseplant; it’s attractive‚ hardy‚ tolerant of many lighting conditions but fond of low light‚ fast-growing‚ pest-repellent‚ safe around children and pets‚ and almost impossible to kill. The golden pothos vine is one of the most popular and dependable houseplants available today. These plants grow to giant proportions in their native habitats. Their mature

There is an overabundance of green plant life that strives on the heavy rains received each year. The forest floor is full of nutrients which the large tree strive on giving the canopy effects and which houses so much plant and animal life. 2.
