How are water and

Answer :

  • The minerals are dissolved in the water. Unlike human beings, plants do not have a circulatory system.
  • They use the two vascular tissues called xylem and phloem for transportation of water and minerals.
  • The main materials of transport are gases, water, hormones, minerals, organic material etc.
Transport in Plants:

Water transport:
  • The root hair absorbs water.
  • The water gets transported and reached xylem vessels.
  • There is a continuous uptake of water from the root to the xylem vessels.
  • This continuous uptake creates a root pressure which allows water to be pushed upwards from the root to the plant body.
  • In tall plants, like trees, this pull of water is created because of transpiration.
  • Transpiration occurs through leaves (water from root reaches leaves and gets evaporated).

Mineral transport:
  • Minerals are transported via xylem as well.
  • Minerals are dissolved in the water and transported along with it.
  • Organic compounds that are produced during photosynthesis get transported through phloem sieve tubes.
