Unlike animals, however, plants use energy from sunlight to form sugars during photosynthesis. In addition, plant cells have cell walls, plastids, and a large central vacuole: structures that are not found in animal cells. Each of these cellular structures plays a specific role in plant structure and function. Plant Organ Systems In plants, just as in animals, similar cells working together form a tissue. When different types of tissues work together to perform a unique function, they form an organ; organs working together form organ systems. Vascular plants have two distinct organ systems: a shoot system, and a root system. The shoot system consists of two portions: the vegetative (non...

Differences of simple tissues and complex tissues? complex tissues are made up of more than one type of cell.They are both conducting tissues and constitute a vascular bundle,Where as simple tissues is parenchyma type of permanent tissues in some situations, it contains chlorophyll and performs photosynthesis, and then it is called chlorenchyma. What are the two types of permanent tissues? there are two types of permanent tissues 1.simple permanent tissues 2.complex permanent tissues simple permanent tissues are made up of only one kind of tissue. eg.parenchyma,sclerenchyma and collenchyma compex permanent tissues is a group of tissues eg. xylem and phloem in stem

For example- parenchyma is a simple tissue which is composed of thin-walled polyhedral, isodiametric living cells with sufficient cytoplasm and one or more nuclei.Phloem is a complex tissue that is composed of four elements namely, sieve elements, companion cell, phloem fibres, and phloem parenchyma and serves in translocation of organic nutrients.

Simple tissue is composed of only one kind of cell, and complex tissue is composed of two or more kinds of cells. Simple Tissues There are five types of simple tissue: epidermis, parenchyma, collenchyma, sclerenchyma, and cork Epidermis covers the outer surfaces of leaves, young roots, and stems. As plants (especially woody plants) age, the epidermis (a primary tissue) on stems and roots is replaced by bark (a secondary tissue). Stomates are found with epidermal cells on leaves and stems but not on roots. Epidermal cells are living. They are almost entirely covered on the outer surface by a waxy cuticle, which retards water passage. Figure 26-1 Parenchyma, an unspecialized living tissue having conspicuous intercellular spaces. Parenchyma cells are commonly isodiametric (as broad as they are long) and have thin walls, living protoplasts, and conspicuous intercellular spaces. Parenchyma is regarded as an unspecialized tissue. If the cells have chloroplasts, the tissue is called chlorenchyma. In p...

\( \newcommand\) Plants\(_2\) classification: overview. Epidermis and Parenchyma Why did plants go on land? In order to escape competition with other plants for resources like the sun and nutrients, but also to obtain much more sunlight that was otherwise seriously reduced underwater. The move to land also helped plants escape predators. Lastly, plants benefited from this change because they escaped from the temperature-gases conflict: warmer temperatures are good for organisms but significantly decrease the amount of gases diluted in water. Although this action solved several problems, it also raised new issues that needed to be dealt with. The most important was the risk of drying out. To combat this, plants developed their first tissue: epidermis (complex surface tissue) covered with a cuticle (plastic-like isolation layer) which served a purpose similar to a plastic bag. For the really small (millimeters) plant it is enough because, in accordance to surface / volume law (i.e., when body size grows, body surface grows slower then body volume (and weight)), they have high relative surface, and diffusion can serve for gas exchange. However, bigger plants also need to exchange gases, and they developed stomata which served as a regulated pore system. The remaining cells became second tissue: parenchyma (tissue or cell type of spherical, roughly connected living cells) or ground tissue (same as parenchyma (see) but only applied for tissue), or main tissue).

Plant Tissue Definition Plant tissue is a collection of similar cells performing an organized function for the plant. Each plant tissue is specialized for a unique purpose, and can be combined with other tissues to create organs such as leaves, flowers, stems and roots. The following is a brief outline of plant tissues, and their functions within the plant. Types of Tissue in Plants Meristematic Tissue Meristematic plant tissue is different than all other plant tissue, in that it is the main growth tissue of the plant. All cells originate from one meristem or another. The apical meristem is the plant tissue which drives above ground growth, and decides the direction of the plant. Root meristems dig into the soil in search of water and nutrients. Subapical meristems divide the plant and carry leaves in different directions. Intercalary meristems provide growth from the middle of the plant, to extend the leaves upward into the sunlight. Meristematic plant tissue, at the central point, is undifferentiated and ready to divide into any other type of plant cell. Meristematic cells divide asymmetrically. This means that one plant remains undifferentiated, while the other cell takes on a more specialized form. This cell will then continue to divide and develop into a plant tissue, which can help form a new organ, such as a leaf. In this way meristematic plant tissue is equivalent to animal stem cells. These cells are totipotent or pluripotent, meaning they can divide into many dif...
