Green plants absorb light energy using chlorophyll in their leaves. They use it to react carbon dioxide with water to make a sugar called glucose. The glucose is used in respiration‚ or converted into starch and stored. Oxygen is produced as a by-product. This process is called photosynthesis. Temperature‚ carbon dioxide concentration and light intensity are factors that can limit the rate of photosynthesis. Plants also need mineral ions‚ including nitrate and magnesium‚ for healthy growth. They

Abstract: Symbiosis is very important in the plant world. Fungus has a symbiotic relationship with other plants. This may help the plant through tough times‚ for example; droughts and long winters. There are many careers that study the problems of symbiotic plants. Symbiosis with Plants Symbiosis with plants is very important. Fungus helps the plant live through tough times. There is a lot of information available about symbiosis but there are also many unanswered questions. Certain careers

between plants and people is made possible by the differences between cellular respiration and photosynthesis. While cellular respiration occurs in all living organisms‚ photosynthesis relies on chlorophyll and is unique to plants‚ algae‚ and some bacteria. Respiration and photosynthesis are essentially the same process in reverse. During photosynthesis CO2 and H2O are converted to glucose and oxygen‚ while cellular respiration uses glucose and oxygen which are converted to CO2 and H20. Plants utilize

Role of mycorrhizas in the mineral nutrition of host plants Mycorrhizas are very important in the uptake of nutrients such as P‚ N‚ K‚ Cu‚ Zn and Ca by plants especially in soils low in these nutrients. Since P is the most limiting nutrient in tropical soils‚ mycorrhizas are vital for improving P nutrition particularly for cultivated plants. External hyphae can absorb and translocate P to the host from soil outside the root depletion zone. The thin mycorrhizal hyphae (2-4 μm in diameter) are able

Heuvelink‚ E.‚ 1987. Influence of light on the growth of young tomato‚ cucumber and sweet pepper plants in the greenhouse: effects on relative growth rate‚ net assimilation rate and leaf area ratio. Scientia Hortic.‚ 31: 161-174. Tomato‚ cucumber and sweet pepper were sown in a greenhouse at regular intervals throughout the year. A relationship between the relative growth rate (RGR) of these young plants and the mean daily light integral ( PAR incoming per unit ground area) could be calculated for

PLANTS AND HUMAN BEINGS Plants and humans are living things that constitute part of the environment. These two depend on each other for their survival. But as plants can live without humans‚ humans can not live for long without plants and this essay explains why this is possible. Plants have the capability to build up organic substances they need from inorganic substances. They only need carbon dioxide‚ water and salts to make their essential substances. Glucose for example is produced from these

started growing plants and herbs - think the best organic cilantro you’ll taste - from seeds. In the process of growing and living with plants‚ I’ve observed them enough to pick up a few life lessons. I didn’t realize how disconnected I was with nature‚ until I started having to water baby plants every day with a mister‚ and checking to see if any leaves had discoloration on my older plants.
