The leaf structure of desert and rainforest plants allow them to survive in their environments by maintain enough water in their system. The climate in the deserts ranges from the temperatures of -18°C to 49°C, along with the average annual precipitation being 25 cm. Desert plants, such as cacti, possess spines (needles or very narrow pointed leave) with a very small surface area and surface area to volume ratio. This allows them to store and conserve water for long periods of time in the hot and dry daytime temperatures of the desert by reducing transpiration (evaporation of water primarily out of plants through their leaves). As a small amount surface area of spines/leaves are exposed to the hot exterior environment of the leaves, that reduces …show more content…

Rainforest leaves are wide/broad, so they have a higher surface area and surface area to volume ratio in general and compared to the spines of desert plants. That being said, the surface leaves of rainforest plants are greatly and constantly exposed to hot sunlight and heat that transfers into the volume of the leaves, which essentially means that transpiration (evaporation) of water is always occurring in the leaves of the plant. With the accommodation of constant precipitation in the rainforest environments, tropical plants are constantly absorbing water in through their roots. And as said already, water will evaporate out of the plant through the pores of the leaves, specifically the stomata in the epidermis, through the process of transpiration. If there was not constant precipitation in rainforest ecosystems, tropical plants would not be able to survive, and would dry out, due to the lack of water combined with constant transpiration of water out of the leaves of the plants. In addition, as the leaves of rainforest plants have a high surface area and surface area to volume ratio, high amounts of sunlight can hit the chloroplasts and perform photosynthesis. The more surface area and surface area to volume ratio a leaf has, the more exposure to sunlight it can get; resulting in more

Another factor is soil. The soil of a rain forest is rare and mostly acidic so plants depend on large trees falling and decomposing for their food. Also, humans moving into more deeper in forests and wild life ecosystems through expansion. Weather and tropical rainstorms could also be a limiting factor because of the intensity of the storms. Coral Reefs-

Elijah Anderson is an author of the text that was read of Urban Experience; it’s titled as The Cosmopolitan Canopy: Race and Civility in Everyday Life. As I read through the text, it made me wondered if places that I’ve been to is considered as part of cosmopolitanism or ethnocentrism. Elijah stated that cosmopolitanism embrace the individuality and achievement, especially through education and experience (p. 189). On the other hand, ethnocentrism embrace the loyalty to their own ethnic group (p. 189). Both of them typically applied onto non-white people, more specifically African-Americans’ attitude and their cultural assumptions and behaviors that come within.

The Minnamurra Rainforest is situated in the Bundderoo National Park, located 15 kilometers west of Kiama on the NSW South Coast, which is less than two hours’ drive from South Sydney. It is at the southernmost limit (34ºS latitude) and is an example of the leftover subtropical and warm temperate rainforest from the ancient super-continent Gondwana (Department of Environment and Conservation, 2004). The Minnamurra Rainforest is located in a large platform carved from the Illawarra Escarpment by the Minnamurra River. It has an inner core of 20 hectares of rainforest that is mostly natural and a larger remaining area of 401 hectares has been disturbed as a result of clearing, fires and floods (Charles Sturt University, 2015). Above the rainforest

To begin, in this lab we studied the structures of leaves under a microscope. A leaf is best described as a major photosynthetic organ of green plants. Plants carry out the process of photosynthesis to convert carbon dioxide and water into oxygen and glucose for usable energy. This can be represented in a general equation which is 6CO2 + H2O -------> (sunlight and chlorophyll) C6 H12 O6 +6O2. Initially, the leaf is protected by the upper and lower epidermis as well as the cuticle.

There are cities, like Philadelphia, that as time passes they start to grow in size and population as a result they have to create recreational places. As years go by, people start to interact more in recreational places until they become a cosmopolitan canopy. According to the book “The Cosmopolitan Canopy: Race and Civility in Everyday Life” by Elijah Anderson, a cosmopolitan canopy is a place that provides opportunities for new relationships to develop and where people come together to socialize and practice getting along with others. In this reading, Anderson also explains that a cosmopolitan canopy is not just created by the place itself or by the diversity of ethnicity, gender, and social class in and around it but also by the “goodwill that is expressed and experienced by most who enter these premises” (Anderson 11). Personally, I agree with Anderson because in order for something to become a cosmopolitan canopy, there has to be difference on the people in it.

In a desert, you will find both a rattlesnake and cactus living in the harsh climate with very little rain. A cactus uses its thick skin of the stem with spines to keep unwanted animals from getting to the water that they store away. It uses its large underground root system to find water deep underground even when the topsoil is dry. The cactus also uses its thick stem to hold water to keep it alive.

Due to the location the temperature in the rainforest stays fairly steady, ranging from about 68℉ to 93 ℉, however, the humidity is also consistent ranging from 77-88% and producing 50 - 260 inches of rain a year. An interesting fact is that the tropical rain forest are thought to produce approximately 40% of the earth’s oxygen, despite only covering approximately 7% of the earth’s surface.

Biodiversity is simply defined as the number and variability of organisms within a defined area. The amount of biodiversity that is present can help to define an area’s richness and productivity. Several factors that help an influence over biodiversity include climate, an area’s isolation, the vegetation structure, and size of the area. Generally, there are more organisms in a warm and moist environment and biodiversity will decline as the climate moves away from the ideal range of conditions. Isolation also plays a key role as more isolated areas usually have less diversity than areas with more connectivity.

Old growth forests are rare to come by, especially in the United States. The Camillus Unique Forest Area, located in northeastern New York, has many characteristics of an old growth forest. It is unclear how old the forest actually is, as the tree species that reside there have a life span of 100-200 years. This could mean that the forest is thousands of years old, with hundreds of generations of these species, or only a few hundred years old, with the first generation just reaching maturity. Either way the forest has many traits of an old growth forest.

Without the transpiration of trees, deforested areas become drier. Changes in weather and shelter cause deforested areas to undergo a tremendous loss of biodiversity. The scientist hasn’t even come close to testing 1% of the plants in the tropical rainforests for medicinal use, but they regularly discover species that are helpful to us the people. But, these forests and their potential benefits are looking like they may disappear by the end of this century if we don’t stop
