Systems of classification Historical development The classification of living things into animals and plants is an ancient one. Aristotle (384–322 BC) classified animal species in his History of Animals‚ while his pupilTheophrastus (c. 371–c. 287 BC) wrote a parallel

A. physiological‚ faster plant growth B. physiological‚ addition of a bitter taste to the plant ’s leaves C. structural‚ increased leaf cuticle thickness D. structural‚ change in leaf color 2.

: How does the different light intensity affect the rate of photosynthesis in plants? Objective : To investigate the relationship between different light intensity (by having the source of light at different distance to the plant discs which is at; 10cm‚ 15cm‚ 20cm‚ 25cm‚ 30cm‚ and 35cm ) and rate of photosynthesis of plant. Introduction : Photosynthesis is the process where light energy is absorbed by green plants to convert the raw materials (carbon dioxide and water) into sugars and oxygen

thaliana is a small plant in the mustard family (Mitchell-Olds‚2001) that became the best studied model system in plant species. Thaliana is considered a weed. The flowering plant Arabidopsis thaliana is a important model system to identify genes and determine their functions. In 1964‚ Plant scientists made a prediction that Arabidopsis thaliana would become the botanical equivalent of Drosophila‚ and history has carried out this prediction. Arabidopsis thaliana was the first plant to have its genome

Temperature also plays a big row in everyday life. For example‚ if the weather is good (no snow) it gives opportunity for more livestock to grow‚ and more carbon-diode to plants and also enough oxygen. But if the weather is cold or it snows‚ trees will be frozen‚ less amount of oxygen‚ carbon-dioxide and sometimes affect the growth of plants and animals. All species in a habitat regulate their own temperature in adapting to the system i.e. one species may be cold blooded or warm blooded and these temperatures

Conclusion INTRODUCTION ON ECOSYSTEM An ecosystem is a community of living organisms (plants and animals) sharing an environment. The largest ecosystems are called biomes. An ecosystem consists of the biological community that occurs in some locale‚ and the physical and chemical factors that make up its non-living or abiotic environment

unreachable for some places were the pollution is starting to affect humans and animals in a serious way. The phytoremediation process‚ is a process that is use to reduce or remove the pollution form land‚ water‚ sediments and air using living plants. In this process the plants degrade of break down the pollutants or remove and stabilize metal contaminants. This is a very efficient process‚ and is one of the most accessible‚ it is estimated that it cost form $25-$100 per ton of soil and $0.60- $6.00 per 100

you increase the light intensity from 10cm away to 20 cm away form a stationary plant. There for the rate of photosynthesis will decrease proportionally with the distance of the light from the plant (in this case a half). This means that as the light moves away then there is less light given to the reaction for photosynthesis to happen. My theory behind this is the following; Photosynthesis is the process that plants use to create energy for themselves. It is best described from the following equation
