Investigating photosynthesis using immobilised algae ...


Class practical This procedure offers a method for measuring the rate of photosynthesis which depends directly on the rate of uptake of carbon dioxide by the photosynthetic organism.

Investigating Enzymes Coursework

All of these methods are necessary to provide cells with the conditions necessary for their survival. It is important to make up enough for the whole investigation as the depth of colour of this indicator is so variable. The indicator is very sensitive to changes in ph, so rinse all apparatus with the indicator before use.

Start with the bottle that has changed most the one at highest light intensity. Make up into balls as above each batch will have a different amount of algae, but the same surface area to volume ratio for the balls. Therefore the dilute solution level will fall and the concentrated level will rise line callout 2 disapproved (is unable to go through the semi permeable membrane o line callout 2 approved (is able to go through the semi permeable membrane p salt solution water image when a substance such as salt di.

A neutral density filter reduces the amount of light transmitted by the same amount at all wavelengths. I think that there will be a slight increase to begin with, but as the body has to work harder i think that the heart will then increase at a faster rate. A collection of experiments that demonstrate biological concepts and processes.

This protocol is adapted with permission from information on the science and plants for schools (saps) website (see you can make up the algal balls in one lesson, discuss how to set up the main procedure, and carry it through in the next lesson. Note the colour of the solution against a standard set of bottles of indicator, andor measure the absorbance at 550nm using a colorimeter. Investigating the rate of diffusion of ammonia investigating the rate of diffusion of hydrochloric acid in agar planning you can change different things you do to an experiment like the amount of acid, temperature, size of the agar or concentration of the acid.

Use a large flat-sided glass vase (available from ikea or homebase or other domestic suppliers) or a medical flat filled with water. Photosynthesis consists of the following equation sun light carbon dioxide water glucose oxygen chlorophyll chlorophyll is a substance found in chloroplasts, found in the cells of. Plotting absorbance against light intensity for the above procedure will show a proportional relationship at low light intensities, levelling off at higher intensities which indicates another limiting factor.

Alternatively you could set up a standard colour scale with buffer solutions and indicator at the same concentration as the reagent in the investigation. ). I will does this twice and take an average prediction i predict that my heart rate will increase as a result of exercise. Equipment hydrochloric acid gelatine tile test tube rubber bung scalpel ruler stop clock goggles measuring cylinder experiment. We can measureobserve on how long it takes to diffuse or the amount diffused each minute.

Investigating Enzymes Coursework

Using a colorimeter (at 550nm) is one way to quantify this procedure. You can also use this technique of immobilisation in an alginate bead to study enzymes or yeast cells. But they do produce heat, so you will need a heat filter for the investigation ( heat filter.

These algal balls make it easy to standardise the amount of photosynthetic tissue in any investigation. Variables the variables that might affect the rate of photosynthesis in this experiment are temperature when the temperature rises so does the rate of photosynthesis this is because as the temperature around the plant rises the enzymes controlling photosynthesis inside the chloroplasts heat up and start moving around faster, the fast moving molecules collide with other fast moving enzymes causing them to react. Start with the bottle that has changed most the one at highest light intensity.

Low hazard once made must be made fresh by qualified staff using fume cupboard. The method with neutral density filters (rather than changing distance from the lamp) is reportedly more accessible for some students. Make a few litres and keep for the duration of the investigations, aerating before each lesson.

Papers investigating the rate of diffusion of hydrochloric acid into gelatine essay example - investigating the rate of diffusion of hydrochloric acid into gelatine introduction in this experiment i am going to investigate the rate of diffusion of hydrochloric acid into gelatine. Note the colour of the solution against a standard set of bottles of indicator, andor measure the absorbance at 550nm using a colorimeter. Use a large flat-sided glass vase (available from ikea or homebase or other domestic suppliers) or a medical flat filled with water.

This protocol is adapted with permission from information on the science and plants for schools (saps) website (see you can make up the algal balls in one lesson, discuss how to set up the main procedure, and carry it through in the next lesson. A neutral density filter reduces the amount of light transmitted by the same amount at all wavelengths. W portable halogen lamps have a stand and handle separate from the body of the lamp which makes them safer to handle.

Hypothesis i predict that the size of the plantain leaves would increase as the light intensity decreases. This is the saps teaching resources webpage which includes links to photosynthesis experiments (accessed october 2011). There is a linear relationship between absorbance of the indicator (at 550 nm bright green filter) and ph over the range studied in this procedure. The beads can be packed into a column (for example, a syringe barrel) and a suitable substrate passed over the beads. There is scope for students to develop the protocol to investigate a range of factors.
