Key differences between plant tissues and animal tissues:
Plant tissues can be composed of one type of cells (simple tissues e.g. parenchyma, collenchyma, sclerenchyma) or of multiple cell types (complex tissues e.g. xylem & phloem), but animal tissues are only complex in nature.
Plant tissues consist of both living and dead cells, for example, tracheids in the xylem are dead elements, but in animal tissues, all the cells are living.
Plant tissues are capable of indefinite growth and differentiation, especially meristematic tissues but animal tissues are themselves highly differentiated, and only reparative growth is observed.
In plants, tissues organize as tissue systems (ground tissue, vascular tissue and dermal tissue) is seen but in animals tissues form organs that work together as organ systems.
Plant tissues are adapted to stationary habits thus require less energy and maintenance but animal tissues require high inputs of energy and higher levels of maintenance due to intensive movement.
