are cytoplasm and mitochondrion. The chloroplast‚ which has two membranes around a central aqueous space‚ is found mainly in mesophyll cells forming the tissues in the interior of the leaf. The chloroplast is made of grana‚ thylakoid‚ and stroma. Chlorophyll‚ which is a green pigment‚ is located in the chloroplasts. The mitochondrion also has two membranes‚ the outer membrane and the inner membrane. Inside the inner membrane is the matrix‚ folded by cristae. Both chloroplast and mitochondrion also contain

The light reactions of photosynthesis contain two photosystems‚ two electron transport chains‚ and ATP synthase. These parts are embedded in the thylakoid membranes of a chloroplast. The photosystems contain a collection of chlorophyll molecules. Chlorophyll‚ which is the green pigment of leaves‚ absorbs light energy that excites electrons to a higher energy level. Energized electrons from photosystem I are passed down an electron transport chain and added to NADP+ to form NADPH. Electrons from photosystem

Why is water important for living organisms? Water is very important in all living organisms‚ it is vital for many different things. Around 70% of our body weight is due to water. The quantity is high in organs such as lungs and brain and fluids such as blood‚ lymph‚ saliva and secretions by the organs of the digestive system. First of all water is vital in the regulation of body temperature to depending on the temperature mammals will alter the amount they sweat. If they are to warm the amount

Photosynthesis Lab Kozlowski Kendal Schweiss Hour 6 Introduction: Photosynthesis is carbohydrate production using light and chlorophyll. It is a process when green plants and other organisms turn carbon dioxide and water into carbohydrates and oxygen‚ using light energy trapped by chlorophyll. The rate of photosynthesis can be measured by either the disappearance of substrate or the accumulation of product. 2H2O + CO2 + light -> carbohydrate (CH2O) + O2 + H2O There is a spongy mesophyll

bacteria (70S). * Proteins of organelle origin‚ like those of bacteria‚ use N-formylmethionine as the initiating amino acid. * Much of the internal structure and biochemistry of plastids‚ for instance the presence of thylakoids and particular chlorophylls‚ is very similar to that of cyanobacteria. Phylogenetic estimates constructed with bacteria‚ plastids‚ and eukaryotic genomes also suggest that plastids are most closely related to cyanobacteria. * Mitochondria have several enzymes and transport

Introduction: All plants need water‚ carbon dioxide and sunlight as these are the main components needed for photosynthesis. The process of photosynthesis occurs in all plants‚ plants absorb sunlight through the leaves using the chlorophyll pigments in the leaf cells. The carbon dioxide diffuses through the stomata‚ under the leaf. The roots of the plants absorb the water from the soil and then the xylem will transport the water and nutrients upward to the leaves. As well as that the

Animal and plant cells are very similar in the way that they create energy to perform their duties. The chemical equations are very similar for cellular respiration and photosynthesis are almost exact opposites. Photosynthesis is anabolic; it builds up glucose‚ or sugar‚ from light energy‚ water and carbon dioxide. The chemical equation for photosynthesis is: 6CO2 + 6H2O + Light Energy C6H12O6 + 6O2. Cellular respiration‚ on the other hand‚ is catabolic. It breaks down glucose to form carbon dioxide

The functions of the nucleus in a plant cell are to coordinate the cell’s activity and store the genetic material. Ultimately‚ plants perform photosynthesis because plants contain chlorophyll. Chlorophyll empowers the cells to use sunlight to convert water and carbon dioxide into sugars and carbohydrates through photosynthesis. Presumably‚ plant cells contain storage vacuoles that store water and they contain ribosomes that make proteins in

Introduction Paper chromatography is a method using a chromatography paper to identify the many mixtures of one simple color. The word chromatography comes from the Greek words‚ "chroma‚" meaning color‚ and "grafein‚" meaning to write. The process of this experiment is to place a colored dot‚ such as marker ink‚ onto the chromatography paper‚ one centimeter away from the triangular tip. Next dip your chromatography paper into the solvent‚ not allowing it to touch the colored dot. Let it sit for

At one point‚ "Protista" encompassed everything that wasn’t an animal or plant‚ until the advent of cellular biology which
