The epidermis is a single layer of cells covering a plant's stem, leaves, flowers, and roots. Select a subject to preview related courses: Epidermal cells can also become very specialized, and since this layer of cells is exposed to the outside world, how they specialize can be significant. It's main function is to protect the body. Enrolling in a course lets you earn progress by passing quizzes and exams. These hairs can even keep dew from forming directly on the leaf surface keeping the stomata protected from being blocked. Think for a moment about what leaves put up with. 's' : ''}}. Plant epidermis is unique because it is actually two different layers of cells: the upper epidermis and the lower epidermis. When stomata open to exchange gases during photosynthesis, water is also lost through these small openings by evaporation. Why is the epidermis important for plants? Get the unbiased info you need to find the right school. The plant endodermis plays an important role in selecting what gets into the plant from the soil. The lower epidermis contains stomata cells that help prevent water loss and regulate the exchange of gases such as oxygen and carbon dioxide, enabling plants to survive. Epidermal tissue system is the outermost covering of plants. A cuticle, made of cutin, is usually present on the outer wall of the cells. It is in direct contact with the environment and so it modifies itself to cope up with the natural surroundings. Conclusion. Plants do not like losing water, and the waxy cuticle of the epidermis helps minimize this loss, keeping plants from drying out. The epidermis is actually interrupted by small pores called stomata. Sandwiched in between these two layers are two other important tissue systems - the vascular tissue system and the ground tissue system. An error occurred trying to load this video. It is a continuous lay­er except for certain small pores, called stomata and lenticels. The lower epidermis contains stomata cells that help prevent water loss and regulate the exchange of gases such as oxygen and carbon dioxide, enabling plants to survive. It is commonly found in the root of the plant. The epidermis may be thicker in some plants living in dry habitats or often secrete a waxy, water- resistant layer on their outer surface called cutin (chemical substance with waterproof quality) to prevent water loss.
