Onda‚ Kristal H. TTH 8:30-10:00 am BSAC3 BIOLOGY 1. How plants grow and develop? Just as humans have essential needs for survival‚ all plants require several basic elements to grow and thrive‚ including… Soil minerals (the more nutrient-rich the soil‚ the better the plant will grow) Water Air (carbon dioxide‚ hydrogen and oxygen) Sunlight Proper soil temperature Proper air temperature How much a plant needs of each element initially depends on the plant’s original habitat. For example

RHODOPYTA (RED ALGAE) Red algae have been the 1st eukaryotes formed by endosymbiosis involving photosynthetic prokaryotes. Red algae are mostly multicellular It exhibit some of the most complex life cycles It posses cellulose walls‚ chlorophyll a‚ some posses chlorophyll d (chloroplast is present but lacks grana) Contains phycoerythrin‚ phycocyanin and allophycocyanin as accessory pigments. flagella is absent in red algae as well as centrioles 5‚000 species(approximate number of known species)

Spinacia oleracea‚ is a highly adaptable organism‚ with the ability to grow virtually universally. While S. oleracea can tolerate a relatively high range of growth temperatures‚ it generally thrives in cooler environments of approximately 20ºC. As global warming becomes an increasing issue of global concern‚ it is becoming increasingly essential to determine the effects environmental temperature change will have on these globally depended upon organisms. The process of photosynthesis allows plants

Photochemistry From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search Illustration of the electromagnetic spectrum. Note the visible spectrum‚ as well as ultraviolet and infrared regions. Photochemistry‚ a sub-discipline of chemistry‚ is the study of the interactions between atoms‚ small molecules‚ and light (or electromagnetic radiation).[1] The pillars of photochemistry are UV/VIS spectroscopy‚ photochemical reactions in organic chemistry and photosynthesis in biochemistry

by green plants and transformed into chemical energy. All photosynthetic organisms contain chlorophyll‚ a green pigment found in plant chloroplasts. There are three types of chlorophyll pigment – a‚ b and carotenoids. Chlorophyll a is the pigment primarily responsible for the process of photosynthesis. It is green as a result of reflecting green light rays. Light energy is captured by chlorophyll and used to form ATP molecules‚ which are in turn used as an energy source by plants in a chemical

Column and Thin Layer Chromatography: The Separation of Spinach Pigment Abstract Spinach extract was separated into fractions containing compounds of similar polarity by column chromatography. Based on solid-liquid phase partitioning‚ this separation technique exploited the different polarity of the compounds in the spinach extract. Three fractions with different colors were obtained. The extract and its fractions were analyzed using thin layer chromatography (TLC). The TLC results showed that

orange and or red pigments. Chromoplasts are found commonly in flowers and fruits. Chromoplasts also divided into three types based on their color namely chloroplast‚ phaeoplast and rhodoplast. Chloroplast: It is in green color. It contains chlorophyll pigments. It is found in higher plants and green algae. Phaeoplast: It is dark brown in color. It contains fucoxanthin pigments. It is found in brown algae‚ diatoms and dinoflagelates. Rhodoplast: It is red in color. It contains phycoerythrin

metal complex chromophores arise from the splitting of d-orbitals by binding of a transition metal to ligands. Examples of such chromophores can be seen in chlorophyll (used by plants for photosynthesis)‚ hemoglobin‚ hemocyanin‚ and colorful minerals such as malachite and amethyst {this paragraph needs correction: there are no d-orbitals in chlorophyll and the colour of amethyst is due to F-center}. A common motif in biochemistry is chromophores consisting of four pyrrole rings. These come in two types:
