The secretory tissue is the one that is structured by the cells that are in charge of making, storing and eliminating the essences that the plant does not use in its vital functions. These substances can be articles or residues of metabolism, which is a set of reactions that occur continuously in living cells, through which it obtains and transforms matter and energy, among which can be found lipids, which are organic substances that are mainly composed by carbon and hydrogen, alkaloids are organic chemical compounds nitrogenated by the basic character that is constituted by certain products such as nicotine or caffeinewhich also belongs to cocaine and morphine, tannins are rough substances produced from glucose produced by some vegetables that are used in the preparation of dyes and to tan leather, those obtained from ketones, fatty acids and other active principles.
Within this tissue there are different types such as epidermal cells, lysigenic bags, schizogenic cavities, laticiferous tubes.
The epidermal cells are those that are located in the epidermis of the vegetable that can form glandular hairs, which are responsible for the smell of aromatic plants such as mint.
The lisígenas bags are holes that are created from different secretory cells applied to the gland or organ whose function is to draw and expel a substance by lysing the membranes and walls separating them.
The esquizógenas cavities are hollow or tubes formed in the function of a group of cells that surround them their secretions where many essences together.
The laticiferous tubes are the conductors associated with the phloem or scattered throughout the plant tissues formed by the plurinucleated cells that make latex and accumulate inside the small cavities of the existing ones in the cytoplasm of a cell by a membrane, which are filled of air or different substances that can be performed by various functions and can be released if the tubes are broken.
