Photosynthesis Lab Report

Introduction: All plants need water, carbon dioxide and sunlight as these are the main components needed for photosynthesis. The process of photosynthesis occurs in all plants, plants absorb sunlight through the leaves using the chlorophyll pigments in the leaf cells. The carbon dioxide diffuses through the stomata, under the leaf. The roots of the plants absorb the water from the soil and then the xylem will transport the water and nutrients upward to the leaves. As well as that the roots also store nutrients and anchor the plant. Plants also need Nitrogen to allow them to photosynthesis.
Plants will undergo osmosis, which is the process that transports water and nutrients from where there is lots of it to where there is less;
Each pot was filled with the same amount and type of potting mix. Then the Climbing Bean seedlings were planted into the soil. The Climbing Bean seedlings need approximately 100 millilitres of the fertiliser mixture every second day. One pot was given no fertilizer, which was watered every second day with 100 millilitres of water, while another one was also watered every second day with 100mililetres of the Organic fertilizer. The last pot was also watered every second day with 100mililetres of Thrive fertilizer. The fertilisers were made by adding one level spoonful of the mixture in 4.5 litres of water. Every second day the plants height and width were measured and recorded, as well as that, the amount of leaves that had sprouted or that were fully-grown were also counted and recorded every second day. The independent variable in this experiment was the type of fertiliser. In the experiment the dependent variables were the height, width and amount of leaves. The control variable during this experiment was the pot that was given no fertiliser. The fixed variables that stayed the same during the experiment were the type of plants used, the amount of water given, the type of potting mix, amount of sunlight, time for growth, all
The organic plants had grown more than the control plants but not as much as the Thrive plants. The Thrive plants had grown the most because of the ingredients that the Thrive fertiliser contains. The difference between the Thrive fertiliser and the organic fertiliser is that the Thrive fertiliser contains added nutrients that are absorbed through the roots and the leaves. The organic fertiliser also relies on the natural ingredients like the use of carp in their fertilisers, which isn’t a targeted ingredient that fertilisers like ‘Thrive’ might include. The Thrive fertiliser also includes organic ingredients like the ‘Organic’ fertiliser but isn’t based on an animal so has no smelly odour that can come from manure or fish. The ‘Thrive’ plants grew more than any other plants as these plants had additional scientifically-proven ingredients that targeted plant health and growth. One of the main ingredients that the Thrive fertiliser includes that the organic fertiliser doesn’t is boron, which helps build cell wall strength and seed development. As it was said in the introduction, some fertilisers can have extra ingredients to target good plant health, like the
