The water droplets formed in the jar is due to the process of transpiration. This takes place through the xylem tissues (Option a).
- The xylem is a tubular tissue found in all flowering plants. Its primary function is to transport water absorbed by the roots from the soil to all the parts of the plant.
- Xylem is composed of four different elements- tracheids, vessels, xylem fibres and xylem parenchyma. All these elements together help to carry the water up the plant against gravity.
- Sometimes, the requirement of water by the plant is lower than the rate of water transport up the stem by xylem. This results in the loss of water from the stomata in the leaves by the process of transpiration.
- Some plants like Eicchornia lose water as droplets from the tips of leaves through hydrathodes. This process is called guttation.
