Why are stomata absent in root |
|
Answer» Because no photosynthesis takes place in roots. Stomata are tiny pores that are found on the epidermis of leaves, stem and some fruits . Stomata are present on aerial parts of plant for transpiration to occur. Roots are present in soil which would block them.\xa0Stomata on the upper surface prevent excessive loss of water due to transpiration as this surface is directly exposed to sunlight. In aquatic plants stomata are either absent or non-functional. Stomata are absent in roots because roots are under the ground and no transfer of air takes place there.and sunlight can\'t reach there. |
