In this photosynthesis experiment, we are going to determine the effect of different light colors on the rate of photosynthesis. Photosynthesis is the phenomena in which solar energy is converted into useful bond energy. Different wavelengths (monochromatic light) have different effect on the photosynthesis. This experiment is performed to identify those changes. Apparatus/Chemicals for Photosynthesis Experiment Beaker, (Water Plant)fresh Hydrilla shoots, ...

In this experiment extraction of amylase from wheat seeds and the effect of amylase on the breakdown of the starch is observed. The effect of temperature is also observed on the activity of the enzyme. Apparatus/Chemicals Slightly grown wheat seeds, starch solution, I2-KI solution, watch glasses, mortar. Procedure Germinate about 30 grams of wheat until their roots are 0.5 cm ...

Soil experiment is used to test the water holding capacity of soil. The Amount of water retained and stored in a soil after watering and subsequent drainage is important in plant growth and hydrological studies. This storage capacity of the soil is called its water holding capacity. That part of the stored water can be subsequently being removed by a ...

By using paper chromatography experiment we can determine more than one type of pigments are involved in the photosynthesis. Photosynthetic pigments carry out photosynthesis. Pigments (organic molecules) are separated by dissolving them in organic solvent and are separated by paper chromatography. In paper chromatography separation of the molecules is governed by the following points. Electrostatic forces of pigment molecules. Molecular ...

Benedicts test procedure is used to detect the presence of sugars present in any chemical. That’s why Sugars can be divided into reducing and non-reducing. This division is on the basis of their ability to react with any reducing agent. Reducing Sugars: All those sugars, which have actually or potentially free aldehyde or ketonic group are known as. Non-Reducing Sugars: ...

Determination of the Effect of Environmental Factors on the Rate of Transpiration of a Leaf Shoot by Means of a Potometer. Objective To demonstrate that different environmental factors has different effects on the rate of transpiration. Transpiration is the loss of water in the form of water vapors from the surface of the plant. It can be, Stomatal Transpiration: When ...

Determination of uptake of water by swelling seeds by seed imbibition experiment when placed in sodium chloride solution of different concentrations. Objective of Seed Imbibition Experiment This experiment is performed to demonstrate the phenomena of imbibition as a method used by the plants to acquire water, especially in seed germination. Imbibition is a special type of diffusion in which net movement of ...

(Procedure of gram staining method Helps to Classify Bacteria into Two Groups)­. Gram staining method is used to distinguish and classify bacterial species into two large groups (gram positive and gram negative). The name comes from the Danish bacteriologist Hans Christian Gram who developed the technique.   Apparatus/Chemicals for Gram Staining Method The apparatus need to use in Gram Staining Technique are droppers, ...
