Plantas y sus células en ingles
If you would like to see an actualphotograph of a chloroplast viewed through the lens of an electron microscope, visit the Nanoworld Image Gallery (you'll need to register in order to view the gallery).
In photosynthesis,the chloropyll (KLOR-a-fil) takes in energy from sunlight. The energy comes in the form of a tiny bundle known as a photon. The photon hits a molecule of water inside the chlorophyll. The photon's energy splits thewater molecule into hydrogen and oxygen. The hydrogen combines with carbon dioxide (which the plant has absorbed from the air) to make sugars or glucose. The oxygen is released back into theatmosphere to give us more air. Did you know that the largest suppliers of oxygen in the whole world are tiny plants known as photoplankton? They are found in the oceans and are really important to giving usthe oxygen needed to keep life going on our planet.
Believe it or not, a plant uses only about one-sixth of the energy it gets from the sun to nourish itself. The rest of the energy is stored in theglucose until it is eaten by other animals or humans. What an amazing process!
Cell types
▪ Parenchyma cells are living cells that have diverse functions ranging from storage and support tophotosynthesis and phloem loading (transfer cells). Apart from the xylem and phloem in its vascular bundles, leaves are composed mainly of parenchyma cells. Some parenchyma cells, as in the epidermis,...
