Class IX: Biology Chapter 5: The fundamental unit of life. Chapter Notes Key learnings: 1) In 1665‚ Robert Hooke first discovered and named the cells. 2) Cell is the structural and functional unit of all living organisms. 3) Organisms may be unicellular or multicellular. A single cell constitutes the unicellular organism whereas many cells coordinately function in case of multicellular organism. 4) The size‚ shape and volume of the cell are related to the specific function that they

of leaf pigments in acetone‚ forceps‚ scissors‚ acetone‚ a quart jar with a lid containing solvent of petroleum ether and acetone and chromatography paper stapled into a cylinder marked with a pencil line about 1cm from one end. An extract of chloroplast pigments where obtained and a blender was used to rupture the cells. Pigments were then extracted with acetone an organic solvent. Then pigment extracts were separated using paper chromatography. Pigment extract was applied to a cylinder of chromatographic

experiment is primarily based off of the process of photosynthesis. The experiment tracks the rate of photosynthesis as it is affected by the color of the light source. Changing the light bulb color changes the length of the wavelengths that hit the chloroplasts in the plant leaves and effects how fast or if photosynthesis occurs. The equation for photosynthesis is 6 CO2 + 6H2O + light energy=C6H12O6 + 6O2 meaning that when a plant cell absorbs carbon dioxide and water alongside sunlight then the plant

respectively. You may even hear about rRNA which stands for ribosomal RNA. They are called nucleic acids because scientists first found them in the nucleus of cells. Now that we have better equipment‚ nucleic acids have been found in mitochondria‚ chloroplasts‚ and cells that have no nucleus‚ such as bacteria and viruses.

Unit 2. Chapters 9-16. Cell Processes 1. Cellular Respiration‚ Photosynthesis‚ Cell Cycle‚ Mitosis‚ Meiosis‚ & Genetics. Note A: All work must be hand-written‚ including charts & diagrams. Note B: each answer requires more than one sentence & use diagrams whenever possible; failure to use diagrams will result in less points. Chapter 9 Outline 1) Principles of Energy Conservation a) Cellular respiration and fermentation are catabolic(energy – yielding) pathways b) Cells must recycle the ATP
Premium Adenosine triphosphate DNA Cell cycle
The overall reaction sequence is: ADP + Pi → ATP‚ where ADP and Pi are joined together by ATPsynthase Energy is often released in the form of protium‚ or H+‚ moving down an electrochemical gradient‚ such as from the lumen into the stroma of chloroplasts or from the inter-membrane space into the matrix in mitochondria. Structure Located within the mitochondria‚ ATP synthase consists of 2 regions the FO portion is within the membrane. The F1 portion of the ATP synthase is above the membrane
