Photosynthesis (plant nutrition)

  1. 1. Ricardo Serrano Soria
  2. 2. Plants have an autotrophic nutrition because they can produce their own organic matter. They can do this through some processes like the photosynthesis. This processes are:  Absorption  Transport of the raw sap  Gas exchange and transpiration  Photosynthesis  Transport of the elaborated sap  Metabolism and cell respiration  Excretion
  3. 3. Organs: roots Soil Roots Water and mineral salts In this process the plant takes water and mineral salts from the ground inside the roots. Roots hair extend their surface to absorb more water. This inorganic nutrients are called raw sap (water + mineral salts).
  4. 4. Organs: stem The transport starts in the roots where the xyleme vessels are. Then the raw sap travels up often to the leaves. Xyleme vessels
  5. 5. The gas exchange takes place in the leaf stomata. Carbon dioxide enters and the oxygen leaves the plant through the stomata as well water in transpiration. CO2 Organs: back of the leaves H2O O2
  6. 6. In the chloroplast the raw sap ix produced using CO2, H2O, mineral salts and sunlight. CO2 + Raw sap + sunlight = glucose + O2 Oxygen is expulsed from the body and glucose form the elaborated sap. Sunlight CO2 Organs: green parts of the plant Glucose O2 Raw sap
  7. 7. This sap is transported from the green parts of the plant to the roots an other parts in the phloem vessels. Organs: stem Phloem vessels
  8. 8. - Glucose is transformated into complex organic substances in the anabolism. - Glucose is used in cell respiration in the mitochondrion. glucose + O2 = H2O + CO2 + Energy H2O O2 Energy CO2 Glucose Organs: all the cells of the plant
  9. 9. The elimination of waste gases is produced in the stomata in the gas exchange and the transpiration. The other waste products are used in chemical reactions or are accumulated in the cell vacuoles because plants haven´t got specials organs for excretion. Waste products Organs: all the cells of the plant
  10. 10. Depending on energy source used, two processes may take place: 1.- The cell takes in water, carbon dioxide and mineral salts from the outside. Using sunlight, organic matter is produced. In the process, oxygen is released from the cell. 2.- Part of the organic matter produced is used in the mitochondrion, where catabolism takes place. Using oxygen, energy and inorganic substances (water and carbon dioxide) are produced. 3.- As a result of catabolism, carbon dioxide is produced and released outside. 4.- Using energy from catabolism and simple molecules, complex organic molecules are produced (anabolism).
