Effects of Wavelength and Light Intensity on Photosynthetic Activity
Effects of Wavelength and Light Intensity on Photosynthetic Activity ABSTRACT The photosynthetic process of eukaryotes revolves around chlorophyll, the substance that give plants their green color. Plants convert light energy into chemical energy by means of photosynthesis. This experiment tests the reaction rates of a chloroplast suspension against variables of wavelengths and light intensity. Both a control and an experimental cuvette were exposed to a range of 450 to 0nm of light and varying intensities

Light Intensity and Characteristics of Photocells
Light Intensity Characteristics of Photocells The photoelectric effect is defined as the emission of electrons from a material by visible light. The cadmium sulfide photocell is used to act as a conductor once exposed to light, allowing light to travel through. However it also acts as an electric resister (an opposition to a current flowing in a circuit) once not exposed to light. The photocell serves today's cause in a sufficient manner. It is used

Investigating the Effect of Intraspecific Competition on the Growth of Mung Beans
Investigating the effect of intraspecific competition on the growth of mung beans Introduction When plants reproduce, size is highly correlated with reproductive. The struggle for reproductive survival among plants is the struggle to grow in the face of competition from neighbours. So the question this experiment asks is how competition affects the growth of plants. A plant growing in a nutrient-abundant environment free from competition will exhibit maximum growth. One way to address this question
