All cells look the same when newly formed. They then develop into groups of specialised cells called tissues.

Growth patterns of plants?
Flowering plants grow all their life. 1) Stems grow taller. 2) Roots grow longer. 3) Hold themselves upright by most of the stem increase in girth or have some other means of support.

for living things to grow bigger, some of their cells must divide to make new cells.

What are meristem cells?
Plants increase in length by making new cells at the tip of both shoots and roots. Also have rings of dividing cells in their stems and roots to increase girth. These dividing cells are Meristem cells.
