E
cuticle
Verified step by step guidance
1
Understand the role of the cuticle in plants: The cuticle is a waxy layer that covers the epidermis of plants, primarily leaves and stems. It serves as a protective barrier against water loss and microbial invasion.
Identify the function of the cuticle: The cuticle helps prevent desiccation by reducing water evaporation from the plant surface. It also acts as a defense mechanism against pathogens and environmental stress.
Differentiate between the options provided: Apical meristem is involved in plant growth, gametangia are structures for reproduction, stomata are pores for gas exchange, and peristomes are related to spore dispersal in mosses.
Recognize why the cuticle is the correct answer: Among the options, the cuticle is specifically designed to prevent drying out and protect against microbes, aligning with the problem statement.
Conclude with the importance of the cuticle: The cuticle is crucial for plant survival in terrestrial environments, allowing them to maintain hydration and resist microbial attacks.
