When comparing and contrasting the mitochondria and chloroplast‚ a person learns all of the similarities and differences between the two. In this essay‚ you will read about the mitochondria‚ the chloroplast‚ and their biochemical reactions. The mitochondria often referred to as the powerhouse cell is found in the eukaruotic cells. There‚ those cells are often found in groups of hundreds. Mitochondria cells can be anywhere from 1 to 10 um long in length‚ but are able to change shapes‚ move‚ and divide

This is the site of the light dependent reactions 6 O2 Glucose (C6H12O6) moved to the leaf for transport 1. Which part of the chloroplast contains chlorophyll? 2. Where does the CO2 go? 3. Where is the energy from the sunlight used? 4. Name this process

allows plants to grow‚ flower and produce seed. The process of photosynthesis requires an organelle called chloroplast and a pigment called chlorophyll The energy of the light is absorbed by chlorophyll and in turn supplies the plant with energy to transform carbon dioxide and water into oxygen and carbohydrates. (lab handout). The process of photosynthesis requires an organelle called chloroplast and a pigment called chlorophyll. Chlorophyll is a green pigment found in almost all plants‚ algae‚

AN INVESTIGATION OF PHOTOSYNTHETIC ELECTRON TRANSPORT OF CHLOROPLASTS FROM _SILVERBEET LEAVES_ Introduction Photosynthesis is the process by which plants use the energy from sunlight to produce sugar‚ which cellular respiration converts into ATP‚ the "fuel" used by all living things. The conversion of unusable sunlight energy into usable chemical energy is associated with the actions of the green pigment‚ chlorophyll. Light Dependent Reactions are the initial stage of photosynthesis‚ in which solar

Explain in detail why palisade cells in plants contain many chloroplasts Palisade cells are cells which are found within the leaves of many plants. They contain chloroplasts‚ which convert the energy in light to chemical energy through photosynthesis. The cylindrical shape of palisade cells allows a large amount of light to be absorbed by the chloroplasts. Beneath the palisade mesophyll are the spongy mesophyll cells‚ irregularly-shaped cells that having many intercellular spaces to allow the

In 1937‚ Robert Hill discovered that isolated chloroplasts can generate oxygen when they are illuminated in the presence of a suitable electron acceptor‚ even in the absence of carbon dioxide. This finding was a landmark in the study of photosynthesis because it established that the source of the electrons used in the light reactions is water. It also confirmed that the released oxygen is derived from water instead of carbon dioxide. In chloroplasts‚ the final electron acceptor is NADP+‚ which

test was conducted to determine how the relative redox activity of chloroplasts from spinach leaves‚ which were performing photosynthesis‚ would change when in the presence or absence of light. To observe these changes in redox activity‚ the chloroplasts were exposed to DCPIP‚ a chemical that changes color according to such activity. By determining the redox activity of the chloroplasts‚ it could then be inferred which chloroplasts were photosynthesizing more actively than others. Redox activity

utilizable form is something essential for the functioning of any organism. Mitochondria and Chloroplasts are the two primary organelles in eukaryotic cells that involve in the transformation of energy‚ thus in production and consumption respectively. The chloroplast is an organelle present only in plant cells and some prokaryotes. At the same time they are absent in animal cells. It’s through the chloroplast that entry of energy to a cell takes place where sunlight is used to trap and convert carbon

Introduction Photosynthesis takes place in the chloroplast and is the use of sunlight energy for cell processes. It happens through a number of chemical reactions and the transfer of electrons. It is used as the source of energy (ATP) for plants. The reaction equation for photosynthesis is H2O + CO2 + (Light) (CH2O)N + CO2 In the Hill reaction‚ Robert Hill showed how chloroplasts in water can still function if there is light and an electron acceptor to release oxygen. He proved that the oxygen

The effect of differing wavelengths of visible light on the photosynthetic activity of Beta vulgaris Introduction Photosynthesis is a crucial biological process that occurs within the chloroplasts of plant cells where CO2 + H2O + Sunlight C6H12O6 + O2. The chloroplasts use light‚ an electromagnetic energy source‚ to produce food for the plant in the form of sugar molecules. During photosynthesis‚ the excited electrons from the light pass through proteins in the electron transport chain (ETC)‚ where
