All green parts of a plant have chloroplasts. However‚ the leaves are the major site of photosynthesis for most plants. There are about half a million chloroplasts per square millimeter of leaf surface. The color of a leaf comes from chlorophyll‚ the green pigment in the chloroplasts. Chlorophyll plays an important role in the absorption of light energy during photosynthesis. Chloroplasts are found mainly in mesophyll cells forming the tissues in the interior of the leaf. O2 exits and CO2 enters

For my essay I chose to describe the light and dark motifs in "Romeo and Juliet". A motif is a term used to describe a passage in literature that has more than one universal meaning. It is used when a character or narrator is comparing one thing to another. For example the light motifs represent light things such as goodness‚ while dark motifs represent dark things such as death. One light quote from the story is during the balcony scene when Romeo is talking about Juliet. He says "It is the East

there a significant difference in height of Bracken (Pteridium aquilinum) from a light area and a dark area? Abstract: This investigation was designed to compare the height of Pteridium aquilinum in a light area and a dark area of Rushy Plains‚ Epping Forest and to establish if light intensity does have an effect on the growth of Pteridium aquilinum‚ commonly known as Bracken. From my research it was clear that the height of Bracken is affected by abiotic factors‚ other than light intensity‚ such

despite an old grudge. The two central motifs throughout the play are light and dark. In Romeo and Juliet the light and dark concepts also exemplify life and death. The two protagonists‚ Romeo and Juliet‚ portray the motifs of light and dark. The two motifs in the play emphasize the theme of how love conquers all the senses. The motif of darkness is expressed throughout Act I Scene I. From the beginning of the play‚ Montague compares Romeo to things of darkness or death‚ Montague says‚ "Many a morning

In this experiment‚ the class examined how the rate of photosynthesis was affected by different light colors at different distances in shoots of a Cabomba plant. The plants were placed in two different beakers‚ one with recently boiled and cooled distilled water and the other with saturated sodium bicarbonate solution. The three different color photoflood lamps used for this experiment were white‚ red‚ and green at four distances of thirty‚ sixty‚ ninety‚ and one hundred-twenty centimeters away

Light and Dark Motif In order to portray the overall theme of The Scarlet Letter‚ Hawthorne uses motifs‚ which are recurring concepts or contrasts. From the beginning of the novel and throughout‚ there are clear examples of light versus dark that are used to set tone and mood‚ and used for character development. Hawthorne utilizes the idea of light versus dark‚ or day versus night to convey the theme of covert sin and overt abomination. In the beginning of the novel‚ Hawthorne displays this contrast

The effect of light quantity on photosynthesis of green land plants Introduction Photosynthesis is the process of converting light energy into chemical energy (Hoober 1984). Pigments within chloroplasts‚ primarily chlorophyll‚ absorb the incoming solar energy which excites their electrons (Hoober 1984). These pigments exist in photosystems in the thylakoid membrane of the chloroplast (Ladiges et al.2010). As the electrons return to ground level‚ they are captured by the electron acceptor in the
