What layer is more cellular than the other- Dermis or Epidermis?
The dermis is more cellular than the epidermis. The dermis contains a variety of cells, including fibroblasts, macrophages, and mast cells, which play important roles in maintaining the structure and function of the skin. In contrast, the epidermis primarily consists of keratinocytes, which are responsible for producing the protein keratin that helps to form the skin's protective barrier.
The outermost tissue of a young plant is called?
The outermost tissue of a young plant is called the epidermis. This protective layer helps to prevent water loss and protect the plant from environmental stresses.
What are Function of epidermal tissues of plant?
The epidermis is a single-layered group of cells that covers plants' leaves, flowers, roots and stems. It forms a boundary between the plant and the external environment. The epidermis serves several functions, it protects against water loss, regulates gas exchange, secretes metabolic compounds, and (especially in roots) absorbs water and mineral nutrients.
Waxy coating that covers the epidermis of a plant?
The waxy coating that covers the epidermis of a plant is called the cuticle. It helps to prevent water loss and protects the plant from environmental stresses such as pathogens and UV radiation.
What are 3 main function of inflammation?
To get rid of the invading micro organism.
What are the external parts of stem?
The external parts of a stem include the epidermis (outermost layer), the cortex (region beneath the epidermis), vascular bundles (tissue that transports water and nutrients), and the cuticle (waxy layer that helps prevent water loss).
What is the upper epidermis used for?
The Upper Epidermis is used to prevent water loss
Why the root epidermis is not coated with a waxy cuticle?
plant roots posses root hairs which anchor the plant in soil and their major function is to absorb water and nutrients from soil. if there will be waxy cuticle on there epidermis it will be hard for roots to absorb nutrients and water from soil hence plant without water and nutrients will die.
What is one main job the epidermis has?
The main job of the epidermis is to prevent microbial pathogens from entering the body. The epidermis is a barrier for the body.
What nutrients function to prevent the appearance of bilateral symmetrical dermatitis primarily on areas exposed to the sun?
Niacin
What is the main function of Epidermis?
The main function of the epidermis is to act as a protective barrier for the body, preventing the entry of harmful substances and pathogens. It also helps regulate water loss and temperature, and contains cells that produce melanin, which gives the skin its color and helps protect against UV radiation.

What is the purpose of a plant's epidermis?
A plant's epidermis is primarily used for protective purposes, which it does by acting as a barrier to invaders (such as fungi). Another important function is in the prevention of water loss (for this reason, epidermal cells are packed tightly together). This water loss is further prevented by the waxy cuticle layer many plants have, located above the epidermal cells.
What is the role of epidermis in the root?
to protect the plants roots and to prevent water loss
Which part of the leaf can best ne compared be your skin?
The epidermis of a leaf can be compared to the outer layer of human skin. Just like skin, the epidermis acts as a protective barrier, regulates water loss, and helps prevent damage from external factors. Both the epidermis and skin play a crucial role in maintaining the health and function of their respective organisms.
What is the function of step bars as used on cars?
The function of the step bars used on cars is to prevent the main bodywork of two cars or their wheels being damaged if two cars collide. It acts as a barrier.
