The C4 & CAM Pathway Many plant species that evolved in hot‚ dry climates fix carbon through alternative pathways. Under hot and dry conditions‚ plants can rapidly lose water to the air through small pores called stomata. Stomata (singular‚ stoma)‚ are usually located on the undersurface of the leaves. Plants can reduce water loss by partially closing their stomata when the air is hot and dry. Stomata are the major passageways through which CO2 enters and O2 leaves a plant. When a plant’s stomata are

A plants volatile organic compound (VOC) composition is the hand that swats unwanted visitors‚ welcomes visitation from much needed pollinators‚ and the substantial determinant in a plants identity and overall evolutionary fitness within the plant community. Understanding the mechanics of volatile formation is essential in interpreting their importance in plant life‚ and in plant-animal interactions. A huge allocation of energy is assumed to be given to the production of volatiles‚ and is therefore

determination in plants Summary- Evolutionary transitions happened gradually from hermaphroditism to monoec in which multiple sex determining genes are involved which include male-sterility and female-sterility factors. There should not be any recombination between different loci which is the pivotal reason for the genetic degeneration of Y chromosomes. There are several theories attached to Y chromosome degeneration that are reviewed recently . Introduction: why are plant sex chromosomes of

Legend of the Banana Plant In the early days when the world was new‚ spirits and ghosts lurked everywhere. They lived in gloomy caves‚ they hid in anthills and tree trunks they frolicked in nooks and corners under the houses. In the dark‚ sometimes their tiny voices could be heard dimly‚ or their ghostly presence be felt. But they were never seen. It was during these days of phantoms and unseen spirits that a young and beautiful girl lived. Her name was Raya‚ and she was a girl bold and daring

The Salem Harbor power plant is a serious threat to the public health and it may only get worse. There is a severe concern about toxic air emissions from the prior waste disposal practices. That is why Bush’s energy plan doesn’t quite work? In the Salem Evening News it says that‚ "The Bush plan only pays lip service to the threat of global warming‚ the greatest environmental danger of our time." (Kert Davies) The Bush plan may of solved the threat of global warming‚ but in reality Pollution

Jaw crushing plant is primarily used for reducing various kinds of stones and lump materials into medium-grained gravel. The materials to be crushed can be hard‚ medium-hard and soft minerals which compressive strength should be not more than 320 MPA. Our PE series jaw crusher result in higher crushing efficiency. Currently‚ these products become the preferred jaw crusher machine in the production of stone. They are widely used in many industries‚ such as mining‚ metallurgy‚ building material‚ railway

microorganism survival largely related to the suspended solids in the water. A disinfectant is nearly always included in treatment plants of any size. Pinang Tunggal water treatment plant produce 227‚000 cubic meter per day of treated water. The source of raw water for the plants is from the Muda Dam through the Muda River. Their main role of Pinang Tunggal water treatment plant is to inactivate any remaining bacteria as the final unit of treatment and‚ more importantly to provide a residual disinfectant

Animals and Plants Extinctions causes and effects on human Nowadays ‚ animal extinction is a broad issue‚ one that involves the habitats and environments where other species live and interact with one another . Only a minority of people are concerned with extinction in today痴 society‚ while others might argue that it is a small problem because we are beyond the point of evolution and thus don’t really need to rely on other animals at all. According to statistics of scientific research

Khalan A. AP Biology Plants Immune Systems Plants serve as the main source of nutrients for countless organisms such as fungi‚ protists‚ vertebrates‚ and insects. In comparison to humans‚ a plant’s “immune system” is insignificant. However‚ plants have adapted and evolved chemical‚ physical‚ and protein based mechanisms to protect themselves against invaders. A plant’s first line of defense against pathogens is their innate immunity. The “innate-immune system” is a non-specific immune
