A2 biology coursework light intensity

a2 biology coursework light intensity Hello :) i've got to complete some coursework ( 4000 words max report where you have to complete a practical and write up results etc) for my a2 biology course and i'm stuck on what to do the school runs a trip to an animal conservation centre (which i'm attending) which contains small invertebrates, coppiced woodland for different years and other creatures.

This flashcard set encompasses the new specification of aqa biology first started teaching in 2015. Biology a2 aqa - photosynthesis study as light intensity increases, the rate of photosynthesis increases until another limiting factor effects the rate effect of co2 concentration on rate aqa a2 biology respiration 17 terms biology a2 aqa - energy & ecosystems 16 terms. My investiagation is into the effect of light intensity on plant elodea the two different lamp lights im using are blue vs white light i wanted to know what topics to cover in the background info part. A2 biology coursework light intensity video preview stages application and limitations of the demographic transition model ocr gcse business studies qualification information including specification exam materials teaching resources learning resources.

For my a2 biology coursework i have to investigate the effect of an abiotic factor on a biotic factor what investigation can i do with holly (ilex aquifolium) some ideas i had: investigate the effect of light intensity (because i know they are shade resistant), but what relevant biotic factor would i measure height (hard because it grows strangely), leaf thickness, etc. Biology f214 communication, homeostasis and energy instructions to candidates the light intensity was varied by altering the distance (d) between the lamp and the photosynthesising plant the student prepared table 21 to calculate the light intensity. The real aim of an a2 coursework exercise is to produce sufficient data which you can analyse and make use of as knowledge (eg enzymes) as well as a2 knowledge if there turn out to be unforeseen errors in the method, this becomes useful when you are discussing improvements.

I'm doing a2 edexcel biology, and i need help coming up with some ideas for my coursework title i haven't really been able to find anything actually doable on the internet a2 biology coursework help effect of light intensity/height on a specific direction (ie north, south, east, west). A2 biology unit 4 page 1 hgs biology a-level notes ncm/7/09 aqa a2 biology unit 4 contents specification 2 ecology populations 5 the ecological niche 8 food chains and pyramids 11 energy flow 14 low light intensity will limit plant growth regardless of the number of plants present. Published: mon, 24 apr 2017 to understand the importance of photosynthesis, research is conducted to help determine which wavelength of light and light intensity the chloroplast would generate the fastest photosynthetic reaction rate of photosynthesis. Biology unit 2 - free download as pdf file (pdf), text file (txt) or read online for free scribd is the world's largest social reading and publishing site search search.

- biology coursework ¡v does the light intensity affect the rate of photosynthesis the investigation in this experiment i will investigate the affect in which the light intensity will have on a plants photosynthesis process. Biology coursework the aim of this experiment is to investigate the affect of ph on the enzyme amylase the amylase is used to break down the polysaccharide starch the amylase is used to break down the polysaccharide starch. Published: fri, 25 may 2018 lauren saxby compare the concentration of bellis perennis in different areas of light intensity aim: the aim of this study was to compare the concentration of bellis perennis (more commonly known as the english daisy) in different areas of light intensity.

Colour of light coloured filters can be used, but these will affect light intensity by different amounts depending on the colour students should collect and set up all the other apparatus before collecting the boiling tube of pond weed. Investigating the light dependent reaction in photosynthesis it is fairly easy to show that plants produce oxygen and starch in photosynthesis at age 14–16 students may have collected the gas given off by pond weed (for example elodea ) and tested leaves for starch. This scheme covers specification points: 4411 (photosynthetic reaction), 4412 (rate of photosynthesis), required practical activity 6 - investigate the effect of light intensity on the rate of photosynthesis using aquatic organism such as pondweed, and 4413 (use of glucose from photosynthesis.

If light is a limiting factor, increasing the temperature for example will not affect the rate of photosynthesis if instead we increase the light intensity, the rate of photosynthesis will increase. Light needed to provide energy for light-dependent reaction- high intensity of light more energy it provides only certain wavelengths of light are used for photosynthesis- photosynthetic pigments chlorophyll a, chlorophyll b and carotene only absorb the red and blue light in sunlight.

Abiotic means ‘non-living’ and examples of abiotic factors include light intensity all species of plants and animals you encounter in the wild are well adapted to the set of conditions encountered in their usual habitat edexcel a2 biology implementation and assessment guide for teachers and technicians ©pearson education limited 2009. A2 gce biology f214/01 communication, homeostasis and energy oxford cambridge and rsa fig 12 shows the theoretical and actual relationship between light intensity and the rate of photosynthesis rate of photosynthesis light intensity key: the rate of photosynthesis at different light intensities for two different species of plant was. An investigation to measure the percentage light transmission, using a colorimeter, through a solution, from ph 2 – ph 9, in which jelly cubes were immersed over a 24 hour period interpretation written communication of the data c1 pepsin is an enzyme that works in the stomach and has an optimal ph between ph 1 and 4 or in acidic conditions.
