New cells in plants specialise into cells of roots, leaves or flowers.
Unlike animal cells some plant cells remain unspecialised and can develop into any type of plant cell.
The presence of these unspecialised cells means that clones of a plant with desirable features can be produced from cuttings.
Unlike animals, most plants continue to grow in height and width throughout their lives.
Plant meristems divide to produce cells that result in increased height, length of roots, and girth of the plant.
If the hormonal conditions in their environment are changed, unspecialised plant cells can develop into a range of other tissues.
This includes xylem and phloem and organs such as leaves, roots and flowers.
Small pieces of plant tissue (explants) can be treated with hormones. They develop into whole plants. These plants are a clone of the parent plant.
Phototropism increases the plant’s chance of survival.
Light affects the distribution of auxin in the shoot tip. The auxin spreads unevenly, producing uneven growth towards the light.
