INTRODUCTION<br />Lentil plants classification is kingdom: Plantae, division: angiosperms, order: Fabales, family: Fabaceae, genus: lens, species: lens culinaris. The lentils plant size is about 40 cm tall and the seeds grow in pots, usually to seeds in each. Lentil is a pulse, (grain legume), crop. Lentil plants have compounded leafs with 4 to 7 pairs of leaflets. Plants can have single steams or many branches depending upon de population. Flowers begin at the lower branches; each flower produces a short pot containing one or two lens-shaped-seeds. Flowers can be white, lilac or pale blue in color; and are self-pollinated. The seeds come in colors of tanned, brown or black.<br />The most important density dependent factors are parasitism and predation, because depending on the density of the population they could or they could not survive to these factors. Parasitism is very important because the higher the density is the higher the level of parasitism, and with predators too because the lower the population density is, the higher the predation level, because of these factors it is why these are density dependant factors that are important and affect the population. Density dependent factors are when the death rate rises as density rises.<br />There are many independent factors that affect the growth of different populations as well as dependent factors, some of these independent factors are: temperature, temperature is very important because the organisms that compose a population need an optimal range of temperature for surviving and for increasing or decreasing their number of individuals, rainfall is an important independent factor because almost every organism in the world is made of water so its important for its survivorship, this is linked with temperature and can also affect the soil pH, the soil pH is important for plants and as these organisms compose the base of food chain its important to take in count the nutrients that soil provides, which are many such as nitrogen, water, phosphorus, magnesium etc.<br />2.OBJECTIVES<br />2.1 To determine how density dependent factors affect the growth of lentil populations.<br />2.2 To determine how density independent factors affect the growth of lentil populations.<br />3.PROCEDURE<br />Put one lentil on five different cups<br />Infer conclusionsTake notes and compare the resultsWait until the 80 lentils grow at the different conditions of densityPut ten lentils on other five different cups.Then put five lentils on other five different cups<br />4. HYPOTHESIS<br />Which plant population has the fastest growth?<br />The population of 5 lentils will grow the fastest because they are able to protect from parasitism and at the same time they can grow freely without being crowded. The population of 5 lentils is the middle point.<br />5.RESULTS<br />5.1 CHART OF RESULTS<br />Date#1 Lentil5 Lentils10 LentilsApril 1410cm0cm1.5cmApril 1420cm0cm0.5cmApril 1430cm0cm0cmApril 1440cm0cm0cmApril 1450cm0cm0cm1234512345<br />5.2GRAPH<br />We realized that the plants didn’t grow in a proper way because of the lack of water that the plants had during the days we didn’t visited the laboratory, the lentils that are alone and the ones in groups of 5 didn’t grew at all, the ones that were in groups of ten grew a little bit more because of the watering conditions. The average show in the graph is<br />1lentil: 0cm<br />5 lentils: 0cm <br />10 lentils:0. 5cm<br />
