When we speak of plant tissues we refer to that conglomerate of cells with the same condition, which are united with each other in a solid and lasting way in order to form solid or laminar groups, with a common mission; that is to say, they are groups of cells that are similar in reference to their form and function, that fuse to develop exactly the same function. Each of the plant tissues is made up of cells called eukaryotes of a plant nature. In a more specific way, plant tissues derive thanks to the consecutive division of the cells that make up the seed embryo that is formed after fertilization that occurs in plants. These plant cells that make up the plant can be living cells, which are responsible for the plant's own development, photosynthesis, substance storage, respiration, growth and damage repair; and dead cells, which provide support and resistance to the plant thanks to their lignified and thickened walls, forming various conductors for the raw sap.
In a plant there can be several types of tissues that differ according to their function, among them are the protective tissues, conductors, growth tissues, parenchyma, support, secretory and meristematic.
Protective fabrics, as their name says, are those fabrics in charge of protecting the plant, forming an external layer in it to protect it from external agents; It is made up of the epidermal or epidermis tissue and the suberous or subber tissue.
Conductive tissues: these tissues are formed from different types of cells and hence they are called the most complex tissues, since most of them derive from meristematic cells; There are two types of conductive tissues that are xylem and phloem, which constitute the vascular or conductive system of plants.
Growth tissues: these also called meristems are made up of young cells that continually divide through mitosis; the cells of these originate the cells that form the plant. The growth tissues have a large nucleus with abundant cytoplasm.
Parenchymal tissues: they are in charge of nourishing the plant, located in all plants, they take care of filling those free spaces that other organs and tissues leave; There are several types, where one of them is responsible for photosynthesis.
Supporting tissues: these are made up of cells whose cell walls are thick to provide high mechanical resistance; They share the same function but differ due to their structure and the texture of the cell walls they possess, as well as the location of each one within the plant.
Secretory tissues: made up of diverse structures, with the only characteristic in common is that of storing and secreting substances into the external and internal cavities of the plant; There are several types of these tissues according to their location.
Meristematic tissues: they are responsible for plant growth, in a longitudinal and diametrical sense; cells in these tissues have a dual capacity to differentiate and multiply.
