What is the role of epidermis in plants

Epidermis is present on the outer surface of the whole plant body. The cells of the epidermal tissue form a continuous layer without any intercellular space. It performs the following important functions:- Cells of epidermis are water resistant thus prevent excess loss of water. It is a protective tissue which protect the plant body It allows exchange of gases through the stomata. Question Description What is the role of epidermis in plants?

• Plant leaves are very important structures as they help to maintain life on earth by generating food (sugars) via photosynthesis. • Leaves can have different shapes and sizes. The basic components of leaves in flowering plants (angiosperms) include the blade, the petiole, and the stipules. • There are three main tissues found in leaves: the epidermis, the mesophyll, as well as vascular tissue. Each tissue type is composed of layers of cells. • In addition to performing photosynthesis, some plants have other highly specialized functions. Examples include carnivorous plants that can 'eat' insects. • Some animals, like the Indian leafwing butterfly, mimic leaves to camouflage themselves from predators. Basic Leaf Anatomy of Flowering Plants. Evelyn Bailey Leaves can be found in a variety of shapes and sizes. Most leaves are broad, flat and typically green in color. Some plants, such as conifers, have leaves that are shaped like needles or scales. Leaf shape is adapted to best suit the plant's Blade - broad portion of a leaf. • Apex - leaf tip. • Margin - leaf edge boundary area. Margins can be smooth, jagged (toothed), lobed, or parted. • Veins - vascular tissue bundles that support the leaf and transport nutrients. • Midrib - central main vein arising from secondary veins. • Base - area of the leaf that connects the blade to the petiole. Petiole - thin stalk that attaches the leaf to a stem. Stipules - leaf-like structures at the leaf base. Leaf shape, margin, and venation...

\( \newcommand\) • • • • • • Learning Objectives • Describe the difference between meristematic and non-meristematic tissues. • Compare and contrast dermal, ground, and vascular tissue. Plants are multicellular eukaryotes with tissue systems made of various cell types that carry out specific functions. Plant tissues are composed of cells that are similar and perform a specific function. Together, tissue types combine to form organs. Each organ itself is also specific for a particular function. Plant tissue systems fall into one of two general types: meristematic tissue, and permanent (or non-meristematic) tissue. Cells of the meristematic tissue are found in meristems, which are plant regions of continuous cell division and growth. Meristematic tissue cells are either undifferentiated or incompletely differentiated, and they continue to divide and contribute to the growth of the plant. In contrast, permanent tissue consists of plant cells that are no longer actively dividing. Meristematic tissues consist of three types, based on their location in the plant. Apical meristems contain meristematic tissue located at the tips of stems and roots, which enable a plant to extend in length. Lateral meristems facilitate growth in thickness or girth in a maturing plant. Intercalary meristems occur only in monocots, at the bases of leaf blades and at nodes (the areas where leaves attach to a stem). This tissue enables the monocot leaf blade to increase in length from the leaf base; f...
