What plant tissues are called the main ones? Why are they absent in animals?

The main tissue in plants performs the function of formation and accumulation of nutrients. In a plant, it is located in the pulp of a leaf, stem, root. The main tissue contains chlorophyll pigment, that is, organic matter (glucose) is created in it and the energy of solar radiation is accumulated in the process of photosynthesis. Animals do not have a basic tissue, since they cannot synthesize organic substances from inorganic ones like plants, they themselves feed on ready-made organic substances, therefore they do not need this type of tissue.
