Plant physiology

low-density wood species, such as Eucalyptus, Pinus and Acacia are largely used for timber, paper pulp, charcoal and fuel, because they have short rotation period and they have advantages in competing for light, nutrients and water resources over native plants (Li et al., 2014; Nguyen et al., 2014; Chaudhary et al., 2016). In temperate and boreal zones, Populus are planted to provide shelter, protect soil and water resources, and sometimes produce wood fuel. For Salix species, they can be used…

Why are they Endangered? There are various reasons why the Amur leopard is endangered, such as the destruction of their habitat, hunting and inbreeding. Firstly the prime area in which the Amur leopard lives is the forests of Eastern Asia. These forest areas are often purposefully burnt down by the local villagers to help the profitable growth of ferns. These ferns are a very popular ingredient in local Chinese and Russian cuisine. The forest fires are the largest contributor to the Amur…

Plant Material Collection Fully grown whole plants of Tribulus terrestris Linn. were collected from different localities of Chennai, Tamilnadu. The fruits were separated out from the plants and washed in running tap water to remove adhering dirt and soil particles and dried first under shade in room temperature and secondly in a hot-air oven for complete drying at 50-60˚C. The dried fruits were made into coarse powder by grinding and stored in labelled bottles for further study and…

saprophytic fungi cause decay and decomposition in various bodies of dead animals and plants. Due to their property of decomposition they convert various complex compounds into simple compounds by secretion of certain types of enzymes. Some of these simple compounds are then absorbed by soil which results in the formation of humus. Certain fungi produce associations with the roots of plants and helps them in taking up of nutrients. This association is called Mycorrhizal Association. They…

carrots, lettuce, apples, etc. All the products are fed lizards must be previously well washed. It should be carefully monitored to ensure that fruits, vegetables and herbs are environmentally friendly, in any case should not be given to animals, plants treated with chemicals or grown near highways. Occasionally it is recommended to give the lizards boiled rice or potatoes.Vegetables and fruits, it is desirable to mix to a diet of animal food was more varied. If the lizard constantly refuses any…

For almost eight million years, humans lived in small bands or groups that were mostly family based, mobile, and almost had no specialization of skills. But for the last ten thousand years humans have been living in states; densely populated, economically complex, socially unequal, governmentally controlled, unstable, and urban civilizations. There are many positives to living in such a manner, but this way of living does have some negatives as well and can be a less satisfying way to live.…

the main producer is plant that plays a very significant roles in order to sustain the growth population. Basically, plant producing their own food by undergo photosynthesis in the help of sunlight energy. The next trophic level which is herbivore will consume it and proceed to next food web. This phenomena lead to determine either the growth rate in certain ecosystem or habitat is higher or lower. For example paddy plants, it is only life once, which means once the paddy plants harvest it will…

refers to the general geographical area and includes vegetation types such as Forest, Nama Karoo, Succulent Karoo and Thicket Biomes. The fynbos biome only covers about 6, 7 % of South Africa and has the highest number of plant species than any other biome in our country. About 7 500 plant species are found within the fynbos biome. Figure 1: Map of the fynbos biome Apart from its uniqueness, the fynbos biome is also very threatened…

How does light filtration affect the rate of photosynthesis? Introduction: Photosynthesis is an essential process plants use to convert light energy from the sun into chemical energy, released as glucose. Some of the limiting factors of photosynthesis include temperature, amount of light, the concentration of carbon dioxide, availability of water and the concentration of chlorophyll. Fig.1- The word and symbol equations for photosynthesis. The aim of the practical is to model the rate of…

that trees normally provide us with shade whenever the sun is hot. Trees also help in preventing soil erosion. They also make our compounds beautiful and attractive. They are also known to purify the air around us. This is the reason why most people plant trees around their homes. However, these trees can be problematic. They can grow too big to the extent of interfering with the foundation of your house. In addition, a limb of a tree can fall on your house while you are away at work. You need…
