Question

How do Root cells increase in size?

Answer 1

There are several components to a plant. Different components are responsible for different functions. The shoot system is the part of the plant that shows above ground level, while the root system is the component of the plant that resides beneath the earth.

Complete answer:
All vascular plants have roots, which are the most essential subterranean component. This portion of the plant is primarily important for attaching it to the soil and absorbing critical mineral components, nutrients, and water. It can also be used to keep food.

However, not all plants have roots that develop underground; others have roots that grow above ground. These are referred to as aerial roots. Aerial roots, like subterranean roots, are important for absorbing nutrients, anchoring and affixing the plant to objects such as adjacent walls, rocks, trellises, and so on.
Bonsai, Banyan Trees, Mangroves, and other plants with aerial roots are a few examples.

Seed germination is the start of root development. The radicle of the plant embryo produces the root system after it emerges from the seed. The root cap, which is unique to roots and unlike any other plant structure, protects the tip of the root. Because the root cap is readily destroyed as the root pushes through the soil, it is changed regularly.

The root tip is split into three zones: a cell division zone, and elongation zone, and a maturation zone. When meristematic cells divide, roots expand. Meristem cells are a kind of cell found at the terminals of plants' shoots and roots. They have been termed stem cells because they are the source of many of the cells that go on to rapidly differentiate/specialize and create various sections of the plant as undifferentiated (or barely differentiated) cells. Thus, Root Cells Increase in Size with the help of meristem cells.

Note: Root architectures vary depending on the needs of the plant. Aerial roots and store roots are two forms of specialized roots. Aerial roots are structural roots that grow above the earth. For food storage, storage roots (such as taproots and tuberous roots) are altered.
