Expert Answer:

Some important keys in nutrition in plants:

  • Autotrophic nutrition is the mode of nutrition in which organisms synthesise their own food from simple inorganic substances such as water and carbon dioxide.
  • Plants are autotrophs and synthesise their food by photosynthesis.
  • Photosynthesis is a physiological process by which plant cells containing chlorophyll produce food in the form of carbohydrates using carbon dioxide, water and light energy. Oxygen is released as a by-product of this process.
  • The palisade layer is the centre for photosynthesis. Light energy is trapped in the chlorophyll of the mesophyll cells in the palisade layer of leaves.
  • The two main phases of photosynthesis are light dependent phase and light independent phase.
  • Light dependent phase occurs in the thylakoids of the chloroplast while the light independent phase occurs in the stroma.

In addition to these key point, you can go through the video lessons available on the website which may help you to clear your concepts.
