How are water and minerals transported in plants?
- 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.
- 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).
- 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.
