Plants grow after being cut because intercalary meristematic tissues remain active at nodes and internodes. These cells divide rapidly and produce new branches or shoots, helping grasses, hedges and other plants regenerate after cutting or grazing.

The increase in girth is caused by continuous division of cells in the lateral meristem. These cells form new tissues concentrically inside and outside the stem, increasing diameter, producing annual rings and strengthening the plant body over time.
Plant and animal tissues differ because plants are fixed and require support, transport and growth tissues. Animals move actively and need flexible tissues for movement, coordination and sensing. Their tissues develop differently according to nutrition methods, body structure and lifestyle.
Plants grow in girth through the activity of lateral meristem present along the stem circumference. These actively dividing cells produce new cells inside and outside, increasing stem thickness and forming annual growth rings in woody plants gradually.
In multicellular organisms, similar cells form tissues, tissues combine to form organs organs work together as organ systems and organ systems form an organism. This hierarchical organisation ensures proper coordination, efficient functioning and successful performance of complex life activities.
