Investigation to find out how light intensity effects the rate of photosynthesis
Words • 3198
Pages • 13
Flowering plants, like all living organisms, need a supply of food. They need it as a source of energy in respiration and they need it as raw material for growth and repair. Animals and most micro- organisms get their food in an organic form: they eat products from other organisms (such as fruit and eggs) or, nowadays, the organic substances made in laboratories and factories. Animals and the microorganisms that do this are called consumers. Due to the flowering plants…...

This shows the author’s view on beauty. He is ambivalent about the permanence of beauty. Keats believes although there is pleasure in beauty, as he says in Endymion ‘A thing of beauty is a joy forever’, beauty is not perfect everywhere. As he is dying, he sees that beauty in people is ephemeral, unlike the figures on the Urn whose beauty ‘cannot fade’ and the nightingale’s song which is so old it may have been heard by ‘the sad heart…...

Light when reflected from another surface reveal many fascinating properties, one of these is known as polarization. Polarized prescription sunglass utilizes this property of light to reduce the glare from surfaces such as glass, snow and water. Generally a source of light produces waves which spread in all direction. When light bounces from flat road surface or smooth water surface, these light waves are horizontally polarized which implies that they move along an axis which is generally horizontal. This leads…...

An emmetropic eye is one in which the eye focuses parallel light rays on the retina at the back on the eye (Benjamin and Borish 2006). An eye which is unable to focus parallel light rays on the retina is said to have refractive error. Refractive error can be instigated by the axial length eye or the refracting powers of an individual's eye. Refractive error can be measured objectively during retinoscopy as well as a subjectively using a Snellen or…...
