- The epidermis consists of the upper and lower epidermis; it aids in the regulation of gas exchange via stomata. The epidermis is one layer thick, but may have more layers to prevent transpiration. The cuticle is located outside the epidermis and protects against water loss; trichomes discourage predation. The mesophyll is found between the upper and lower epidermis; it aids in gas exchange and photosynthesis via chloroplasts.

Eukaryotic Plant Cells: Definition, Examples & Characteristics The cell wall, located on the outside of the cell membrane, is a rigid structure composed of the carbohydrates cellulose and pectin. It provides protection and flexible support for the plant cell. Similar to our skeleton, the cell wall provides structure and shape for the plant.rganelles Specific to Plant Cells. It can be difficult to remember the functions of all the different eukaryotic organelles. One of the most common memorization techniques to do this is to write a silly rhyme using the organelle's name and job.

- The mesophyll is the main inner leaf tissue making up the blade of the leaf. Most of the photosynthesis of the plant takes place in the mesophyll. The mesophyll in the upper part of the leaf is made up of tightly packed cells, full of chloroplasts, and is called the palisades layer.The mesophyll in the lower part of the leaves is made up of loosely packed cells and is called the spongy layer.The vascular tissue functions like the circulatory system of the plant. The xylem carries water from the roots to the leaves and to the other upper parts of the plant.he mesophyll in the lower part of the leaves is made up of loosely packed cells and is called the spongy layer.

The Structure and Function of a Cell Wall While all plant cells have a middle lamella and primary cell wall, not all have a secondary cell wall. Middle lamella - outer cell wall layer that contains polysaccharides called pectins. Pectins aid in cell adhesion by helping the cell walls of adjacent cells to bind to one another.

Structure of Leaves: The Epidermis, Palisade and Spongy Layers Below the cuticle is the epidermis. On the top of the leaf, this is known as the upper epidermis. This is a single layer of cells found directly below the cuticle. It helps protect the leaf by aiding in preventing water loss and providing an extra layer between the outside and inside of the leaf.he Structure of Leaves. Leaves are vital to the survival of plants. They help plants in a variety of ways, including producing food and oxygen through photosynthesis, balancing water loss, regulating gas exchange and transporting the products of photosynthesis.

Plants and Their Environment 1 Tissues – Groups of cells that are similar in appearance and function, for example: 2  Epidermis is the single exterior layer that protects the stems, leaves, flowers, and roots. 3  The outside surface of the epidermis tissue is usually covered with a waxy substance called cutin, which reduces water loss. In a carrot, for example, the parenchyma cells become a storage unit called the cortex. 2  In leaves, a layer of parenchyma tissues under the epidermis is active in photosynthesis. 3  When wounded, parenchyma cells can become meristematic and proliferate to grow over the wound.

Plant Cell Cell membrane: It is the outer lining of the cell which encloses all other cell organelles. The cell membrane also known as the plasma membrane is semipermeable. It allows only specific molecules to pass through and blocking others. Cell wall: The cell wall is a rigid layer that surrounds the plant cells. Plant cell walls are primarily made up of cellulose. It is located outside the cell membrane whose main function is to provide rigidity, strength, protection against mechanical stress and infection.

Epidermis In plants, the epidermal cells secrete further protective substance (called cuticle) to prevent desiccation (water loss). A plant leaf is lined with two layers of epidermis (i.e. upper and lower): one on top of and another one below the mesophyll layer.he epidermis is a protective outer covering of many plants and animals. It may be comprised of a single layer, as in plants, or of several layers of cells on top of the dermis, as in those of vertebrate animals. The primary role of the epidermis is to protect the more susceptible layers of the skin.
