The answer is quite simple -- photosynthesis! Chloroplasts within plant cells allow plants to carry out photosynthesis to keep it alive! ]]> 2020-09-22 16:10:13 UTC https://padlet.com/hchen48/g4zkc01m332zgj6j/wish/768858054 Structure of Chloroplast hchen48 https://padlet.com/hchen48/g4zkc01m332zgj6j/wish/768874074
  • Chloroplasts are one of several different types of plastids, plant cell organelles that are involved in energy storage and the synthesis of metabolic materials.
  • All green structures in plants contain chloroplast, but leaves are the major sites for photosynthesis.
  • The chloroplast is different from most other organelles because it has its own DNA and reproduces independently.
  • They are found mainly in the cells of the mesophyll, the tissue of the interior of the leaf.
  • A typical mesophyll cell has 30-40 chloroplasts. Each chloroplast contains two membranes that surround a fluid called the stroma.  
  • Within the stroma is a third membrane system known as thylakoids. Stacks of thylakoids host the green pigment Chlorophyll that gives the leaf color.

    - At the same time, chlorophyll absorbs light energy from sunlight and converts it into chemical energy.
    - Chemical energy also leads to the production of organic compounds such as glucose. The organic compounds are sources of energy for the plants and were stored in the chloroplast until transported to other parts of the plant through veins.]]>     2020-09-22 16:19:55 UTC https://padlet.com/hchen48/g4zkc01m332zgj6j/wish/768908571     The Importance of Chloroplast hchen48 https://padlet.com/hchen48/g4zkc01m332zgj6j/wish/768950067 - Photosynthesis, which is carried out by the chloroplast, is crucial to the survival of not only plants but our entire ecosystem!
    - This is because photosynthesis is plants' main source for energy. It also provides energy to the animals that consume them.
    - Photosynthesis also absorbs CO2 and release O2 which is importance for the survival of all living things.
    - This is why trees are so important especially in urban areas where the carbon production is high.]]>     2020-09-22 16:28:19 UTC https://padlet.com/hchen48/g4zkc01m332zgj6j/wish/768950067     hchen48 https://padlet.com/hchen48/g4zkc01m332zgj6j/wish/768979268 2020-09-22 16:34:08 UTC https://padlet.com/hchen48/g4zkc01m332zgj6j/wish/768979268 Chloroplast vs. Mitochondria hchen48 https://padlet.com/hchen48/g4zkc01m332zgj6j/wish/768981265 Chloroplast and mitochondria are the two organelles that produce energy in a plant cell. While chloroplast functions during the day through photosynthesis, mitochondria functions at night through cellular respiration.
    Cellular respiration is the metabolic process that uses oxygen to produce the chemical energy known as ATP.
    This shows a potential downside of chloroplast. It can only function during daylight. Therefore, plants have to absorb O2 at night through cellular respiration.
    This is why some experts do not suggest having plants in bedrooms at night, as plants will compete against us for oxygen.]]>     2020-09-22 16:34:29 UTC https://padlet.com/hchen48/g4zkc01m332zgj6j/wish/768981265     Further Reading hchen48 https://padlet.com/hchen48/g4zkc01m332zgj6j/wish/769009038 2020-09-22 16:39:44 UTC https://padlet.com/hchen48/g4zkc01m332zgj6j/wish/769009038 My Sales Pitch hchen48 https://padlet.com/hchen48/g4zkc01m332zgj6j/wish/769015438 I did not read the directions for the video fully before starting.
