Tissue decreases the workload of individual cells.ġ.It increases the efficiency of multi-cellular organisms. Tissues become organized to form organs, which in turn form organ systems.The division of labour increases the survival rate of the multicellular organism. Tissue brings about division of labour in multicellular organisms.Now you must be wondering, what is the importance of tissues in multi-cellular organisms? Or why do we need tissues? Let us have a look. are different types of tissues found in plants.ĭid you know? The branch of science that deals with the study of tissue are called histology. For example, Blood, bone, cartilage are some examples of animal tissues while xylem, phloem, parenchyma etc. The tissue is a group of cells with common origin, structure and function that work together to perform a particular function. Division of labour has been made possible by specialization of cells and their grouping with each specialized clusters of cells in a definite place in the body. Such a group of cells are called tissues. Each cell is specialized to perform different functions.They show the division of labour. However, in multicellular organisms, there are millions of cells. The single cell performs all basic life activities like movement, intake of food, digestion, respiration, excretion, reproduction etc. Unicellular organisms like Amoeba and Paramecium has a single cell in its body.
