Thank you for using LearnNext Q&A forum. Please post questions individually for clear and prompt answers. Anyway, your answers are here.
a) Stomata are small pores occuring in the epidermal cells of the leaf. Stomatal number is more on the surface of the leaf. Stomata, a pore and the surrounding guard cells make up stomatal apparatus. Guard cells can change their shape to open or close the stomata.
Hydathodes are secretory tissues present in the leaves. These secrete water drops through pores in the epidermis. Hydathodes are supplied by vascular bundles. Excess water in the vascular bundle is exuded by hydathodes.
b) Stomatal transpiration is the type of transpiration which occurs through small pores on the leaf called as stomata. 70%-80% of total transpiration occurs in the form of stomatal transpiration. Stomatal transpiration occurs during the day time as the stomata remain open during the day time.
Lenticular transpiration is the type of transpiration which occurs through the small pores present in the bark. It constitutes about 15%-20% of total transpiration. It occurs throughout the day and night.
c) Guttation is the process by which a plant loses exudats water from hydathodes. Guttation is caused by positive hydrostatic pressure which develops in the xylem cells of the root. Guttation helps the plant to cool its body and regulate its temperature.
Bleeding is the process by which plant loses its substances from the wound. Latex and other exudates are collected from the wound caused in the plant body.
