Life starts from a single cell called a zygote. It divides repeatedly through mitosis to form many cells. These cells differentiate into tissues organs and organ systems, eventually developing into a complete multicellular organism with specialised functions.

In multicellular organisms, specialised cells form tissues, tissues form organs and organs form systems. Each structure performs particular functions efficiently. This division of labour improves coordination, reduces workload on individual cells and enables organisms to perform complex life processes successfully.
Plant tissues mainly provide support, transport and continuous growth because plants remain fixed in one place. Animal tissues help movement, coordination and rapid responses because animals move actively. Structural differences arise from different lifestyles, nutrition methods and body requirements.
The study of cells and tissues helps us understand growth, repair, transport, movement and coordination in living organisms. It also supports medical research, tissue culture, disease treatment, crop improvement and scientific advancements that improve agriculture, healthcare and overall human welfare.
“Tissues in Action” explains how similar cells group together to form tissues that perform special functions. Different tissues help organisms grow, move, transport materials, protect the body and coordinate activities. This division of labour increases efficiency and supports complex life ...
