Imagine a camera that is composed with 2 million working parts‚ and stored up to 24 million images around you throughout life span. This incredible amazing camera is our eyes. The human eyes are one of the most interesting medical field that are being studied‚ as well as one of the most complex organs that has many features. The eyes are the organs of sight and one of our special senses. Vision is our one of our dominant sense: 70% of all the sensory receptors in the body are in the eyes‚ and almost

Keratinocytes: The most numerous cells are the keratinocytes which produce keratin‚ a fibrous protein responsible for protective properties of the epidermis. Melanocytes: located at the base of the epidermis. Specialized cells that synthesize the pigment melanin. Melanin protects the cell nucleus from the destructive effects of UV radiation Langerhans cells: arise from the bone marrow and migrate to the epidermis and other areas of the body containing stratified squamous epithelial tissue.

allows for wavelengths that are beyond the visible spectrum to be created. Any light reflected is a direct result of wavelengths that were not absorbed and have been stripped of any white light wavelengths. Any color that is primarily absorbed by a pigment molecule will have the reflection of light in the opposite range of color. Structural colors are created from reflection‚ diffraction and refraction. At times‚ light can reflect away from an object creating many fragments‚ so it is said

plants‚ for animals that eat animals that eat plants" for animals that eat animals that eat animals that eat plants‚ etc. (Levine 726) All humans rely on these plants to produce oxygen from photosynthesis. The presence of light and of the green pigment chlorophyll makes the change of carbon dioxide and water to glucose and oxygen possible. It was Jan Ingenhouz with Jean Senebier in Geneva that founded the basic gist of the theory of photosynthesis in plants. My experiment involves testing different
Premium Chlorophyll Photosynthesis
In plants‚ the pigments in chlorophyll are used to absorb the light energy from the sun to aid in the process of photosynthesis (Biology 102 Lab 7). Specific wavelengths are assimilated into the pigments; however‚ not all wavelengths will be absorbed into the plant. The wavelengths not absorbed will reflect off of the plant and act as the visual representation

Anthocyanins and other pigment chemicals of the larger family of polyphenols in purple grapes are responsible for the varying shades of purple in red wines.[7][8] Grapes are typically an ellipsoid shape resembling a prolate spheroid. Most grapes come from cultivars of Vitis vinifera‚ the European grapevine native to the Mediterranean and Central Asia. The potential of black grape‚ as an ink‚ is the anthocyanins in its content. Ink is a liquid or paste that contains pigments or dyes and is used to color a
