Class: Environmental systems and societies Teacher: David. A Student name: Krutarth Mehta Date: 13/3 Relevant to: 2.5.2. Describe photosynthesis in terms of inputs‚ outputs and energy transformations. Criteria to be assessed: PL‚ DCP‚ DEC. Background: Photosynthesis is the reaction carried out by green plants to produce a supply of food. The reactions occur in the chloroplasts and require light energy. 6CO2 + 6H2O C6H12O6 + 6O2 In aquatic plants

Hydrilla Verticillata more known as Hydrilla. Hydrilla is an Herbaceous perennial‚ which means it is a type of plant that’s growth dies off after time‚ but its roots survive and keep growing. Hydrilla requires a wet habitat to live‚ it can also reproduce in two different ways: Through fragments of the stems‚ or through the axillary buds(tubers). One single tuber‚ can produce more than 6‚000 new tubers. (Sutton et al. 1992) These tubers attach to the roots‚ and buried in the wet soil. Some Universities

Hydrilla: An Invasive Species Hydrilla verticillata‚ otherwise known as Hydrilla is an aggressive water weed and is said to be one of the world’s worst invasive aquatic plants. Hydrilla in temperate places around the globe and somehow made its way to the United States. Hydrilla has a special advantage; it grows under lower light conditions than nearly any other species‚ it only needs about 1% of sunlight. This advantage allows hydrilla to grow underneath other plants and survive greater depths;

food contamination and disturbance in the food chain. Researchers have long been searching for answers for the elimination and prevention of water pollution‚ which will cost less than the usual and commercial methods used. Hydrilla (Hydrilla verticillata) is a halophyte. Hydrilla verticillata‚ a profusely occurring submergent specie‚ has been found to thrive well in highly polluted water (Sinha‚ et al.‚ 1993). In addition‚ the plant has shown promise in the removal of heavy metals (Gupta and Chandra

study aims to determine if the color of light affects the amount of oxygen created through the process of photosynthesis by Hydrilla‚ an aquatic plant. It specifically seeks answer to the following problem: 1. Which color of light affects the evolution of oxygen as sign of photosynthesis? Hypothesis The following hypothesis will be tested in this study: 1. Hydrilla will produce the most oxygen when exposed to certain color of light. Significance of the Study The study is significant to

Cut the stem of a Hydrilla plant to about 10cm long under water. 2. Set up the apparatus as shown below. Check the thermometer at intervals to ensure a constant temperature. Renew the water if necessary. 3. Adjust the distance of the bench lamp to 0.1m from the Hydrilla plant. Turn on the lamp and allow the plant to equilibrium

Keeping this in mind‚ what organelle do you think would be the most numerous inside the cells of your mouth? (Hint: what organelle is responsible for breaking things down and digesting?) lysosomes What is the movement of the chloroplasts in the hydrilla leaf cells? what its direction? and what process could account for the movement of the cytoplasm? Clockwise movement. The lipotubuloids consisting of osmiophilic granules surrounded by a system of microtubules move from one place to another within

The semipermeability of the cell membrane was determined using dialyzing bag models which were exposed into different osmotic conditions. In order to observe the response of animal and plant cells into these conditions‚ red blood cells (RBCs) and Hydrilla leaf were used and were exposed into different concentrations. Both cells exhibited hypertonic and hypotonic solutions when exposed to high and low concentrations respectively‚ while exhibiting isotonic when concentrations are equal. Three experiments
