Answer:
1. Stomata are little openings or pores that empower vaporous trade. Stomata are more often than not found in plant clears out, but they can moreover be found in a few stems. Stomata are pivotal for a plant's life capacities since they permit carbon-containing carbon dioxide gas to enter the plant's tissues.
2. Roots that grow upwards (away from gravity) are called breathing roots. Breathing roots: Underground tissue of any plant requires oxygen for respiration and in a mangrove environment.
