The main functions of the plants tissues are:
Ground Tissue: that tissue is responsible to conduct the basic functions of photosynthesis, food storage, transport of organic and inorganic compounds, and support;
Dermal Tissue: It make up the outer layer of the plant (stems, flowers, leaves, roots) being responsible to help deter the excess water loss and protect the plant from insects, microorganisms, and others environmental impacts;
Vascular Tissue: the vascular tissues of plants are the xylem and phloem, that are continuous systems through the plant working as a transport pathway for nutrients, water, signaling molecules (hormones), as well acting as a support against mechanical stresses, giving form to the plant morphological structure.
