Final answer:
The statement is false. The plant epidermis does include epidermal cells, guard cells, and trichomes, each with specific and important functions for the protection and physiological processes of the plant.
Step-by-step explanation:
False. The epidermis of plants consists of several types of cells, including epidermal cells, guard cells, and trichomes. While epidermal cells are abundant and make up the majority of the epidermis, specialized cells such as guard cells play a crucial role in regulating gas exchange and transpiration through the stomata. Trichomes, on the other hand, are hair-like structures that can help in reducing water loss and providing protection from herbivores.
The structure of the epidermis in plants is crucial for their survival, as it provides a barrier against water loss while allowing for essential processes such as photosynthesis and respiration. The single-layer thickness of the epidermis and the waxy cuticle it secretes are critical adaptations for conserving water. Additionally, the epidermis can be several layers thick in plants living in extreme conditions, further minimizing transpiration.
