has been derived from two Greek wards-auto means self and troph means nutrition. In this mode of nutrition‚ the organisms prepare their own food from simple raw materials like water‚ carbon dioxide and mineral salts in the presence of sunlight. Chlorophylls present in the chloroplast or green plants are the site of food production. Accordingly all green plants are the examples

How light intensity effects the Rate of photo synthesis. Aim The aim of my experiment is to find out how light intensity affects the rate of photosynthesis. Prediction I predict that as the light intensity increases that the rate of photosynthesis will increase in proportion‚ so for example if you increase the light intensity from 10cm away to 20 cm away form a stationary plant. There for the rate of photosynthesis will decrease proportionally with the distance of the light from the plant (in

Sodium hypochlorite‚ also known as chlorine bleach‚ soda bleach‚ or household bleach is a chemical with the formula NaClO. A common way sodium hypochlorite gets into the San Francisco bay is through daily household cleaning products such as laundry bleach. In a survey conducted by The Clorox Company‚ it was found that four out of five households use sodium hypochlorite bleach for their laundry. Since laundry detergent companies are not required to list every ingredient‚ customers are often not aware

ASHITABA PLANT (Jonathan O. Dela Cruz III-Courage) One of the oldest and prominent herbal plants native to Asia‚ grown in rich volcanic soil is Ashitaba. The herbal plant described like "celery - like vegetable". In China medicinal properties of the plant date back 2000 years‚ during the Ming Dynasty (1368 - 1644) and Shogun warriors (1192 -1867). A Chinese book written by Dr. Lee (1518 - 1593) first describes the medicinal value of Ashitaba during the Ming Dynasty. Ashitaba known to purify blood

appearance of brilliant autumn colors. Sugar maples‚ red oaks‚ sumac‚ birch and other trees and shrubs turn from green to bright red‚ orange‚ and yellow. The short‚ cool days of autumn bring an end to the production of chlorophyll (the green light-gathering pigment). As chlorophyll gradually breaks down‚ the colors of the more stable carotenoid (yellow/orange) and anthocyanin (red/blue/purple) pigments become visible. Some years the leaves of a particular species are bright yellow‚ while other years

the sun’s light. Towards the end of summer the trees start to pull the nutrients back into its trunk and starve off the leaves. As those leaves began to starve‚ they stop producing the pigment chlorophyll which gives the leaves their green color. The leaves began to show yellow and red as the chlorophyll breaks down. With no pigment being produced‚ all the leaves will turn color over time. She tells us that there is a pigment called Anthocyanin‚ which causes the leaves to turn red. This pigment

PATTERNS IN NATURE – Summary Notes 1. ORGANISMS ARE MADE OF CELLS THAT HAVE SIMILAR STRUCTURAL CHARACTERISTICS 1.1 Outline the historical development of the cell theory‚ in particular‚ the contributions of Robert Hooke and Robert Brown The Cell Theory states that: All living things are made of cells (Theodor Schwann & Matthias Schleiden) Cells are the basic structural and functional unit of organisms (Theodor Schwann) All cells come from pre-existing cells (Rudolf Virchow) The historical

order to live. Plants capture the energy from the sun and converts it into food that is needed by all plants and animals (including us as humans). In this process the chemical reaction which is known as photosynthesis‚ it takes the sun’s energy and chlorophyll found in chloroplasts in the green leaves of plants‚ to turn inorganic carbon dioxide into glucose (sugar) to make oxygen which we all need to live. So‚ when animals eat the plants‚ and take the carbon in the sugars‚ inside their cells they

Variagated Leaves Total absence of plastid pigments causes a sector of a leaf or stem to have white patches. This condition is termed variegation (Metrosideros). Variegation is produced when there is a cell mutation (cytological chimera)‚ and all cells produced from that mutant mother cell lack the pigments‚ either because plastids are not present or the plastid cannot complete the manufacture of the pigment apparatus. White‚ therefore‚ is where color is missing. The zones where chloroplasts are
