RESPIRATORY PIGMENTS Colored‚ metal-containing proteins that combine reversibly with oxygen‚ found in the body fluids or tissues of multi-cellular invertebrate animals and microorganisms. The role of these pigments is primarily to aid in the transport of molecular oxygen. Thus they are distinguished from respiratory enzymes‚ which are concerned with the metabolic consumption of oxygen. Four distinctly colored groups of respiratory pigments exist among invertebrates: hemoglobins (purple‚ become orange-red

purposes. However‚ meiosis results in sexual reproduction‚ in order to create multicellular organisms‚ occurring in only animals‚ humans‚ fungi‚ and plants‚ whereas mitosis occurs in all organisms. Mitosis only goes through one division‚ has the same number of chromosomes‚ and creates only two diploid cells. Meiosis undergoes two divisions‚ the creation of four haploid cells‚ and half reduces the chromosomes. 6) 7) In the first cell division (meiosis I)‚ homologous chromosomes separate. Meiosis I results

Biology – HSC Online Extract from Biology Stage 6 Syllabus (Amended October 2002) © Board of Studies‚ NSW 9.2 Maintaining a balance: 1. Temperature range Background: All organisms are adapted to a particular environment with its characteristic temperature range. The temperature range allows the organism’s enzymes to control its metabolism by operating at their optimum efficiency within this range. Some organisms are adapted to live at high temperatures (80 - 100oC) and these are called thermophiles

PHOTOSYNTHESIS (How do the light dependent and light independent reactions provide food for a plant?) Why? How important are plants to life on Earth? Could life as we know it continue if there were no plants? Read on the find out why plants are truly the cornerstone of life.

Heat on the pH of the Vegetable and Their Pigment PURPOSE The purpose of this experiment is to see how pH levels of certain vegetables change while being cooked in four different mediums (frying‚ boiling‚ steaming‚ roasting)‚ and how the varying pH levels change the coloring of the vegetables. We will analyze how the different method of cooking/heating changes the levels of pH. BACKGROUND INFORMATION This experiment is based around the different pigments in vegetables‚ of which we researched and

PLANT CELL Introduction Plant cell is the basic unit of structure and function in nearly all plants. The range of specialization and the character of association of plant cells are very wide. In the simplest plant forms a single cell constitutes a whole organism and carries out all the life functions. In just slightly more complex forms‚ cells are associated structurally‚ but each cell appears to carry out the fundamental life functions‚ although certain ones may be specialized
