Which of the following statement for hydathodes is correct
1 Opens to release excessive pure water from leaves
2 Contains loosely arranged parenchyma cells
3 These are found at the tips of the veins in leaves
4 More than one option is correct
Explanation:
All the above A hydathode is a type of pore, commonly found in angiosperms, that secretes water through pores in the epidermis or leaf margin, typically at the tip of the leaf. Water droplets are released from hydathodes on the leaf margin when the absorption of water exceeds transpiration. Hydathode consists of a loose collection of cells called as epithem.
