A tiny hole in the protective barrier layer of leaves is the stoma or stomata.
- The outer layer that covers all the plant's parts from defects is called the epidermis.
- Stomata are the very small holes in that outer layer.
- Allowing only certain substances to pa-ss while others are blocked, this process is done by a semi-permeable membrane.
- This acts as a filter.
- In some high trees, stomata are impermeable.
