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

Fungal endophytes are found in asymptomatic photosynthetic tissues of all major lineages of land plants. The ubiquity of these cryptic symbionts is clear‚ but the scale of their diversity‚ host range‚ and geographic distributions are unknown. To explore the putative hyperdiversity of tropical leaf endophytes‚ we compared endophyte communities along

was once so numerous yet it became extinct in 1914(endangered species act‚ 2015). Awareness to protect species in the beginning of the 20th century began with Theodore Roosevelt establishing the National Wildlife Refuge at Pelican Island‚ an early step aimed at “protecting endangered and threatened plant and animal species”( Endangered Species Act‚ 2013). It took another 70 years for the Environmental Species Act to become law; the Endangered Species Act was signed into law on December 28‚ 1973

Ally Tinnermann Endangered Species Imagine a world filled with millions of different species of animals. Then‚ imagine that same world but with no more mammals‚ amphibians‚ or reptiles. Many people consider themselves animal lovers. So‚ ask yourself‚ it possible to live in a world without animals? An endangered species is a species that is at serious risk of extinction. Jennifer Sexton and Tom Warhol say on their website‚ Endangered species‚ that as the world is continuing to grow at an alarming

Endangered Species; The Cause Needs to Find a Solution There are a plethora of endangered species on the planet today‚ but whose fault is it they’re almost extinct? Are humans to blame‚ or would the natural process of life have destroyed them regardless of our presence on Earth? The fact that we are here‚ and dominate‚ tells me that regardless of if we are the cause‚ we should be the solution. There are over 900 extinct species‚ and 16‚900 endangered (3). We have the capability of slowing‚ or

ss can be judged by the way animals are treated”. There are several animals who are on the line of becoming extinct. Animals that are on the line of extinction are called Endangered Animals. If the current Endangered animals became extinct then many resources that people use will also disappear. We should save Endangered Animals due to that animals maintain healthy ecosystem‚ and animals provide with food source and raw materials. Essentially‚ animals help maintain the healthy ecosystem. The ecosystem is the connected in

Endangered languages: what is to be done‚ and why? The threat to linguistic resources is now recognized as a worldwide crisis. Language death is what happens when the last speaker of a particular language dies‚ or when a language community ceases to exist. It is an extinction that is happening on a massive scale and with astonishing speed. According to Krauss (1992a)‚ as many as half of the estimated 6‚000 languages spoken on earth are "moribund"; spoken only by adults who no longer teach them

Carnivorous Plants In a world where plants are at the bottom of the food-chain‚ some individual plant species have evolved ways to reverse the order we expect to find in nature. These insectivorous plants‚ as they are sometimes called‚ are the predators ‚ rather than the passive prey. Adaptations such as odiferous lures and trapping mechanisms have made it possible for these photosynthesizers to capture‚ chemically break-down and digest insect prey (and in some cases even small animals.) There

Maltese tiger ~Maltese tigers are blue colored-tigers from the South Chinese tiger subspecies. Although there are no known specimen evidence to prove the existence of these critically endangered tigers‚ there have been quite a number of sighting throughout history. Most of the sightings are reported in the Fujian Province of China. Giant Panda ~The Giant Panda is a bear native to China. Pandas can easily be distinguished from other bear species from their coloration. Their diet mainly consists
