A strip of secondary meristem located in the cortex of older plants forms cork tissue, which constitutes the outer protective layer. This process is known as cork cambium activity.

The outer layer of a branch of a tree typically undergoes changes as the plant ages, forming cork tissue to provide additional protection. In contrast, the outer layer of a young stem may consist of primary meristem and epidermal tissue.

Desert plants often have a thick waxy coating of cutin on the outer surface of their epidermis. This cuticle acts as a waterproof barrier, reducing water loss through transpiration and helping the plant conserve water in arid environments.

The long, hairlike structures on the epidermal cells of roots increase the total absorptive surface area of the root system. These structures enhance water and nutrient absorption from the soil, aiding in the plant’s growth and survival.

Stomata play a significant role in transpiration by allowing water vapor to escape from the plant through their pores. The opening and closing of stomata regulate the rate of transpiration, helping to maintain water balance within the plant.

Stomata consist of two guard cells that flank a pore. These guard cells regulate the opening and closing of the stomatal pore to control gas exchange and water loss. The stomatal complex is embedded within the epidermis of leaves.

Stomata are small pores found in the epidermis of leaves, enclosed by two kidney-shaped cells called guard cells. They are necessary for gas exchange with the atmosphere, including the intake of carbon dioxide for photosynthesis and the release of oxygen. ...

The epidermis acts as the first line of defense for the plant, protecting it from various environmental stresses such as water loss, physical damage, and pathogen invasion. By forming a continuous protective layer, the epidermis plays a crucial role in ...

Epidermal cells are relatively flat and often have thicker outer and side walls compared to the inner wall. This structural arrangement reinforces the protective function of the epidermis by providing additional strength and durability.
