Aim: To see if raising the light intensity increases the rate of photosynthesis.

6CO + 6H O ® C H O + 12O (in the presence of light energy and chlorophyll) Aim- The aim of the experiment is to determine what effect light intensity has upon the rate of photosynthesis of Canadian Pondweed (Elodea)....

Prediction:I predict that raising the light intensity will increase the rate of photosynthesis.

Remove several leaves from around the cut end of the stem

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....

I then think that the rate of photosynthesis will stay the same when it reaches a certain point.

Is because
the wants to show that the rates of photosynthesis will
vary according to how much light from a light bulb will be trapped in
the chloroplasts, in the leaf.

Though eventually how ever high the height intensity is the rate of photosynthesis will level off.

Analysis

My graph shows that the closer the distances of the light source the
higher the rate of photosynthesis.

Lina Kim's Biology Blog: Photosynthesis Virtual Labs


My graph has no anomalies, and it closely followed to what I had
predicted that the closer the distance of the light the higher the
rate of photosynthesis would be and thus produce more bubbles in the
time recorded.

It also gives more information about photosynthesis



Variables

Input - Light intensityis to be varied by increasing and decreasing
the distance from the light source to the plant

Output - The rate of photosynthesisis to be measured by counting the
bubbles of oxygen produced by the plant every two minutes, and
therefore finding the rate of photosynthesis

Control - The amount of water available to the Elodea will stay the
same level in the 400 cm3 beaker.

I can say that the
increase in distance thus making the light intensity stronger
increased the rate of photosynthesis and when further away made the
rate of photosynthesis almost come to its limiting factor the
straitening of the graph.

MicroCal is formulated with special spreading agents and dispersants, so no additional adjuvant is required.


Fill tank half full of water, with agitator running, add total amount of MicroCal. Finish filling with desired amount of water. Citrus and Walnuts: Mix 6-8 gallons of MicroCal with sufficient water to make 100 gallons of spray. Apply 100-500 gallons of spray per acre. Apples, Apricots, Cherries, Nectarines, Peaches, Plums, and Prunes: To help prevent sunburn, mix 2-5 gallons of MicroCal in sufficient water to make 100 gallons of spray. Apply 100-500 gallons of spray mixture per acre. Tomatoes, Melons and Peppers: Mix 6-8 gallons of MicroCal in sufficient water to make 100 gallons of spray. Apply 80-100 gallons of spray per acre. Above rates are in a manner as described by "Morshet". Use of MicroCal as a sunblock material will NOT enhance photosynthesis.


To improve soil penetration, addition of penetration agents is recommended. MicroCal can be applied using drip, pivot, or flood irrigation. Soil and plant tissue testing should be performed to determine the calcium needs of each crop and soil type. For most crops 5-15 gallons per acre of MicroCal should be applied through irrigation water.


Repeat application of 1.5-2 qts/acre applied from petal fall up to one month before harvest. A single application of up to 1 gl/acre may be made from petal fall to just after "June Drop". Min water rate: 30 gl/acre. Blueberries: 2 qt/acre applied 10 days after petal fall has finished. Bushes being grown for a second cropping year should receive the fruiting year program again. Water rate: 100 gl/acre. Citrus: 1-2 qt/acre at 13 day interals. Cotton: 2 qt/acre at early flowering. Water rate: 3-20 gl/acre. Cranberries: 1.5 qt/acre at early bloom. Water rate: 50 gl/acre. Deciduous Nuts: 2 qt/acre 7 days after petal fall. Water rate: 50 gl/acre. Almonds: 3 pt/acre in 50-100 gallons of water. 3 applications: 1@5% bloom, 2@ full bloom, 3@ 7-10 days after petal fall. Peas: 2 qt/acre applied at the 4-6 inches stage. Pears: Repeat applications of 1.5-2 qt/acre at 7-10 day intervals applied from petal fall up to 1 month before harvest. Peppers, Tomatoes (field grown): One to four applications of 2 qt/acre from flowering on second truss onwards up to one month before harvest. Stone Fruit: Two applications of 2 qt/acre sprayed 6 weeks and 4 weeks before h Turf: 1.5-3 fl oz/ 1,000 sq ft. Apply as soon as growth commences in the spring and repeat at 10-14 day intervals as necessary. Vines (Grapes): Three applications of 2 qt/acre at bunch closure; start of ripening; and two weeks later. Water rate: 20 gl/acre.


Prior to any fertilizer or pesticide application all spray mixing and application equipment must be cleaned. Tank Mixing: Read ALL product labels carefully and adhere strictly to the instructions for use and advice regarding whether or not products should be tank mixed. Many variables, outside the control of Willamette AG, can influence the performance of tank-mixed products and therefore tank mixing products is entirely at the risk of the end- user. A limited crop area only should be treated initially when using unfamiliar tank mixes. Willamette AG makes no express warranties other than those set forth herein.
