Current Question (ID: 12464)

Question:
Epidermis in plant is generally
Options:
  • 1. Single layered
  • 2. Double layered
  • 3. Triple layered
  • 4. Present in patches
Solution:
The epidermis in plants typically consists of a single layer of cells that forms the outermost protective covering of the plant organs such as leaves, stems, roots, and flowers. The epidermal cells are parenchymatous, which means they are relatively simple and unspecialized, with thin cell walls, a moderate amount of cytoplasm, and often contain chloroplasts. The epidermis serves various functions including protection against water loss, mechanical damage, and pathogen invasion, as well as regulation of gas exchange through specialized structures called stomata. The epidermal cells may also secrete a waxy layer called the cuticle, which further helps in reducing water loss from the plant surface. In some cases, the epidermis may be modified with trichomes (hair-like structures), glands, or other specialized structures depending on the plant species and its ecological adaptations.
