Growth from apical meristems is known as primary growth, which encompasses all elongation.

https://en.wikipedia.org/wiki/Root

In some plants (such as ivy), the "root" actually clings to walls and structures.

https://en.wikipedia.org/wiki/Root

Gravitropism, the growth mechanism of plants that also causes the shoot to grow upward.

https://en.wikipedia.org/wiki/Root

At germination, roots grow downward.

https://en.wikipedia.org/wiki/Root

Over time, given the right conditions, roots can crack foundations, snap water lines, and lift sidewalks.

https://en.wikipedia.org/wiki/Root

Plant roots will generally grow in any direction where the correct environment of air, mineral nutrients and water exists to meet the plant's needs.

https://en.wikipedia.org/wiki/Root

There is correlation of roots using the process of plant perception to sense their physical environment to grow, including the sensory of light, and physical barriers.

https://en.wikipedia.org/wiki/Root

Gradually these cells differentiate and mature into specialized cells of the root tissues.

https://en.wikipedia.org/wiki/Root

The latter (root cap dells) become the primary tissues of the root, first undergoing elongation.

https://en.wikipedia.org/wiki/Root

root cap cells (these are sacrificed to protect the meristem), and undifferentiated root cells.

https://en.wikipedia.org/wiki/Root

The meristem cells more or less continuously divide, producing more meristem.

https://en.wikipedia.org/wiki/Root

Early root growth is one of the functions of the apical meristem located near the tip of the root.

https://en.wikipedia.org/wiki/Root

the vascular tissue in the centre of a root to transport the water absorbed by the root to other places of the plant.

https://en.wikipedia.org/wiki/Root

When dissected, the arrangement of the cells in a root is root hair, epidermis, epiblem, cortex, endodermis, pericycle.

https://en.wikipedia.org/wiki/Root

When dissected, the arrangement of the cells in a root is cortex.(4)

https://en.wikipedia.org/wiki/Root

When dissected, the arrangement of the cells in a root is epiblem.(3).

https://en.wikipedia.org/wiki/Root

When dissected, the arrangement of the cells in a root is epidermis.(2)

https://en.wikipedia.org/wiki/Root

When dissected, the arrangement of the cells in a root is root hair.(1)

https://en.wikipedia.org/wiki/Root

A large range of other organisms including bacteria also closely associate with roots.

https://en.wikipedia.org/wiki/Root

The roots of most vascular plant species enter into symbiosis with certain fungi to form mycorrhizae.

https://en.wikipedia.org/wiki/Root

Roots often function in storage of food and nutrients.

https://en.wikipedia.org/wiki/Root

Roots also synthesise cytokinin.

https://en.wikipedia.org/wiki/Root

 In response to the concentration of nutrients, roots also synthesise cytokinin, which acts as a signal as to how fast the shoots can grow.

3) storage of food and nutrients, 4) vegetative reproduction.

https://en.wikipedia.org/wiki/Root

The four major functions of roots are 1) absorption of water and inorganic nutrients, 2) anchoring of the plant body to the ground, and supporting it,

https://en.wikipedia.org/wiki/Root

The first root that comes from a plant is called the radicle.

https://en.wikipedia.org/wiki/Root

important internal structural differences between stems and roots exist.

https://en.wikipedia.org/wiki/Root

Therefore, the root is best defined as the non-leaf, non-nodes bearing parts of the plant's body.

https://en.wikipedia.org/wiki/Root

Furthermore, a stem normally occurring below ground is not exceptional either.

https://en.wikipedia.org/wiki/Root

roots can also be aerial or aerating (growing up above the ground or especially above water).

https://en.wikipedia.org/wiki/Root

Root.

https://en.wikipedia.org/wiki/Root

In vascular plants, the root is the organ of a plant that typically lies below the surface of the soil.
