Will A Banana Last Longer If It Is Refrigerated, Or If It Is Kept At Room Temperature??

Research Paper

Honors Biology pr. 2

I hypothesize that the Banana WILL last loner in the refrigerator. My organism is the common Banana. Independent variable is the place where the banana is kept, either in the regular air at room temperature, or in the refrigerator. The dependent variable is the temperature at which the bananas are kept.

__CLASSIFICATION__
 * Multicellular
 * Eukaryote. Animals, plants, fungi, and protists have eukaryote cells.
 * Bananas have no tissue.
 * Bananas have no organ systems.

__TYPES OF METABOLISM__ Photosynthesis. Bananas grow on banana trees. Trees, being that they are plants they naturally go through photosynthesis, like most plants and leaves. Yes, chemical reactions are important to the variables because heat can be chemical and can be transferred as energy for the refrigerator, and the air around. __REPRODUCTION__ Asexual. Cells in the banana divide to make copies of that same cell, which become new banana tree seeds. The cell division of a banana is at constant reproduction. Hundreds of offspring may occur. __EVOLUTIONARY INFORMATION __ **Evolutionary History of The Banana Family and Angiosperm.** **The banana family more formally known as Musaceae is a flowering plant or angiosperm This family and group have many distinct characteristics that makes them able to be classified. The life cycle, dispersal mechanisms, physical form, time period, and many other characteristics are all contributing factors to the classification of this particular family.** **Musaceae are a part of the angiosperm group of plants that are mainly characterized by the flowering part of the plant. The main characteristics of angiosperms are flowers, stamens, closed carpels, and endosperm. The earliest dated fossil of an angiosperm is calculated to be 125 million years ago in the cretaceous period The majority of angiosperms really started to appear about 100 million years ago in the mid-cretaceous period. Angiosperms have been dominant ever since, they are the.** The following are sites where info was found: > ([]). > ([]).

__INTERDEPENDENCE__ Bananas are at the bottom of the food chain: It has no way of defense and does not have the ability to harm or consume other organisms. 65% of the animals around them get there energy supply from organisms similar to it. <span style="background-color: transparent; color: #000000; font-family: Cambria; font-size: 11pt; text-decoration: none; vertical-align: baseline;">Predation: Other animals eat bananas, like monkeys and ants eat bananas for energy, but bananas get the energy an food from Photosynthesis.

The habitat in the tropical rainforest would usually be very moist and wet sometime. some abiotic factors would be the water and the trees. Some biotic factors would be the insects that crawl around and the rocks that are laying around in the forests and most important the animals that are there.**The internal factors that are in a tropical rainforests are the climate wich the climate doesnt doesnt stay the all year round in a average year the tropical rainforest would be very human because of all of the rainfall.** The external tropical rainforest gets about 150 cm of rain per year. It has year round of rainy season, this causes the weather to be very hot with a lot of ground moisture, the tempature never goes pat 93 degrees and the lowest that it will ever go would be 68 degrees. The following are sites where info was found: __**DEPENDENT VARIABLE**__ One major variable you will need to consider is that bananas emit ethylene gas, which speeds up the ripening process.
 * __HOMEOSTASIS__**
 * his organism is found in the tropical rain forest.**
