Plant Transport Plants are mostly made up of water. Lettuce is about 94% water and a potato is about 77% water. Plants need water for three main purposes: ------photosynthesis‚ -support -transport of chemicals Water is a raw material for photosynthesis. If water is in short supply‚ the rate of photosynthesis will be limited. Plants need water for support‚ otherwise they wilt. Water is needed to transport many chemicals within plants. Chemicals‚ such as mineral salts‚ dissolve in water and

Copper is an element that occurs in minor amounts in the earth’s crust. Estimates of average crustal prevalence are on the order of 0.0058 percent by weight. Deposits considered to be economically recoverable at current market prices may contain as little as 0.5 percent of copper or less‚ depending on the mining method‚ total reserves‚ and the geologic setting of the deposit. Here is the flow sheet on how to process copper from Zenith. Copper Process Flow Sheet: Copper ore is first quarried from

MAKES VINCA PLANTS GROW THE BEST? My Science Experiment! The experiment is to take 4 Vinca plants‚ which are about the same size‚ health‚ and flowering stages and find out which one will grow the best. Each of the plants will have 75 ml of a liquid daily for 10 days. My Grandma bought them from Lowes on September 20‚ 2011 for me. Breakdown of the plants are as follows: Control plant will get tap water. Plant A will get Milk from the refrigerator. Plant B will get

PLANT RESPONSES TROPISM is a biological phenomenon‚ indicating growth or turning movement of a biological organism‚ usually a plant‚ in response to an environmental stimulus. In tropisms‚ this response is dependent on the direction of the species. The word tropism comes from the Greek trope ("to turn" or "to change"). Tropisms are usually named for the stimulus involved and may be either positive (towards the stimulus) or negative (away from the stimulus). Phototropism is the growth response

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

A world without plants Plants; probably the most ignored organism on this planet. People walk past plant and cut them down but nobody ever thinks about what they do for us‚ what the world would be if there was never any plants or photosynthetic organisms. If the world never had these organisms the world would be a desolate place. There would be no oxygen‚ atmosphere‚ or food. We inhale air unconsciously every day. By taking in air‚ we absorb oxygen and discharge carbon dioxide in the process of

Plant Tour Experience in Wyeth Philippines At Canlubang‚ Laguna Visiting a prestigious plant was a great experience. On that day the feeling of excitement was surrounding me. It was my first time having an educational tour. During the road trip everyone was enjoying talking and cracking some hilarious jokes and enjoying as if we were just a kid that was having a field trip. When we had arrived at Canlubang I was so excited to enter the plant because I was so curious about what was the inside

Abstract The process of photosynthesis can be summarized as the photoautotroph consumption of carbon compounds as food and release of oxygen compounds as waste. The methods to measure the rate of photosynthesis are various. One method utilizes CO2 sensors to measure photoautotrophs CO2 intake under various luminescent environments. An elementary method utilizes H2O and NaHCO3 (Sodium Bicarbonate) for submersion of deoxygenized photoautotroph specimens to measure the release rate of oxygen compounds

Introduction For the past 30 years Scientist have searched desperately for the answer to salt toleration within plants. The damaging effects of salt accumulation in agricultural soils have influenced both ancient and modern day civilizations alike. Worldwide‚ an estimated 24.7 million acres of once agriculturally productive land are being lost annually due to irrigation-induced salinity‚ according to the U.S. Department of Agriculture. Thus‚ crop production is limited by salinity on 40% of
