Nutrition in plants

  1. 1. By: Saamarth Sharma
  2. 2.  Nutrition: It is the mode of taking food by an organism and its utilization by the body.
  3. 3.  Autotrophic: ◦ In this mode ,organisms make food themselves from simple substances. All plants are therefore called autotrophs.  Heterotrophic: ◦ In this mode, animals and most other organisms take in ready made food by the plants.
  4. 4.  Parasitic: ◦ Plants which do not have chlorophyll cannot synthesize there food. They take food from other plants like heterotrophic mode of nutrition. this is called parasitic mode of nutrition.  Saprotrophic mode of nutrition: ◦ the mode of nutrition in which organisms take in nutrients in solution form from dead and decaying matters.
  5. 5.  Water and minerals present in the soil are absorbed by the roots and transported to the leaves .  Cabon dioxide is taken In through the tiny pores present on the surface of leaves these pores surrounded by guard cells is called stomata.
  6. 6.  Some organisms live together and share shelter and nutrients this is called symbiotic relationship.  For example- certain fungi lives in the roots of the tree. The tree provides nutrients to the fungus and, in return, receives help from it to take up water and nutrients from the soil.
  7. 7. Insectivorous plants : the plants which eat other insects are called insectivorous plants. Example: pitcher plant, venus flytrap.
  8. 8. Photosynthesis: The process by which leaves make food with the help of carbon dioxide and water in the presence of sunlight. During this process, carbohydrates are synthesized and oxygen is released
  9. 9.  All organisms take food and utilize it to get energy for the growth and maintenance of their bodies.  Oxygen is produced during photosynthesis.  During photosynthesis plants take carbon dioxide and release oxygen.  The plants which eat other plants are called insectivores plants. Example- pitcher plant, venus fly trap.
