Biodiversity Practical. My prediction is that the location with the greater amount of plant population and biodiversity would be the one with the least human intervention

Biology Biodiversity Experiment Sameer Patel, 1001. Task: Design and carry out an experiment that examines the plant populations and biodiversity at three different sites within the school compound. Aim: To determine whether areas with greater human intervention have an effect on the plant population of the area. Hypothesis: My prediction is that the location with the greater amount of plant population and biodiversity would be the one with the least human intervention- in this case, Plot 2 (Outside the Staff Room/ESL Lab). The location with the least number of plant population and biodiversity would be the one that experiences the most human intervention, i.e. the primary field, which is used on a daily basis by a large amount of people. There is also construction work being carried out near Plot 3 (Behind the Canteen), which therefore could also affect biodiversity and plant population significantly as well. Variables: Independent Dependent Controlled Location Population and Biodiversity Method of Data Collection (Quadrat) Apparatus: * 0.5m x 0.5m Quadrat * Magnifying Glass Diagram: Method: 1) Gather required equipment. 2) Identify locations where data will be collected from. 3) Place the quadrat on the ground within the location where data will be collected from, and record various plant populations and range of biodiversity. ...read more.


The field is used daily by a large amount of little children, and there are only three main types of grass/plants growing there. The area is highly disturbed, which in turn restricts the growth of numerous plant and grass species. A reason why this area has the highest amount of Fat grass could be due to its ability to withstand large amounts of human intervention and cope with the significant amount of disturbances, being stronger and sturdier than most types of grass. This type of grass grows in abundance along with Spiky grass, because hardly any other type of grass or plant species would be able to suit those conditions. Plot 2- As I had predicted, the area outside the Staffroom had the greatest amount of biodiversity, with a range of plant and grass types growing in abundance. The main types (those which were included within the quadrat) were Fat grass, Spiky grass, Clovers, and Dandelions. There was also a significant amount of moss accumulating within the area, and the surface felt different compared to the other two locations. This location had a large percent of Fat grass, the least amount of Spiky grass, and the most number of Clovers and Dandelions. A plant that was exclusive to this plot was the Dandelion, and this was the only area in which they grew. ...read more.


in recent times, and the possibility of it affecting the biodiversity within the area. Due to the construction work being carried out, the surrounding area is becoming more frequently accessed, allowing for more human intervention and disturbance which therefore affects the growth of the plant and grass species in that area. If the experiment were to be conducted again in the future, a change of location would definitely be more interesting. We could try collecting data from locations with a wider variety of species and greater amount of biodiversity, such as the big field next to secondary, or perhaps the garden area around the primary walls. These locations would have a number of different plant and animal types, and in comparison with the locations chosen for this experiment, there would be a larger amount of biodiversity due to a lesser amount of human intervention, as both these areas are infrequently or very rarely accessed by school personnel. Overall, I am relatively pleased with the experiment and the results that we were able to obtain all seem logical enough to provide justification for my hypothesis. Clearly, the area with greater human intervention would have a lesser amount of biodiversity, and the area with a lower amount of human intervention would have a greater amount of biodiversity along with a better range of plant, grass and animal species within that area. ...read more.

    Each species has an optimum temperature at which lives can only survive within a fixed temperature range. Temperature also indirectly influences distribution by affecting water availability and humidity. STREAMS/RIVERS The flow of water is always in one direction, produces many effects that determine the kinds of animals that can live in such habitats.

    The palisade cells have many chloroplasts, containing chlorophyll in the cell cytoplasm. These trap then sunlight for use in photosynthesis. The spongy mesophyll contains many air spaces for gaseous exchange, i.e. for CO2 to reach the cells for photosynthesis and for O2 to be used in respiration and excess to leave via the stomata.
