The organ that holds a plant in place would be the roots. The roots also collect nutrients and water for the plant.
Its roots.

The root system.
Does this include roots?
the roots serve as the anchor of the plant.
Non-vascular plants, such as mosses and liverworts, do not have special tissues to transport water and nutrients. Instead, they anchor themselves in the soil using structures called rhizoids. Rhizoids are root-like structures that provide anchorage, help absorb water, and aid in nutrient absorption, although they do not have the same complexity and functionality as true roots found in vascular plants.
The roots absorb water and inorganic nutrients and anchor the plant body to the ground and help them to grow.
The tap root is the main anchor root, that is its purpose.
Z-discs and Titin.
Soil provides minerals for plants, retains water so that plants can have enough time to absorb it, and helps to anchor plants.
Roots anchor the plant in the ground and supply water and nutrients to the plant to use for growth. Some roots are used to store nutrients for the next season - carrots potatoes.
Rhizoids are thin, rootlike structures that anchor the moss and help absorb water and nutrients from the soil.
The cell wall
With the help of roots, plants absorb water and other essential elements/nutrients like nitrogen, etc. from the surroundings/soil, which aid in plant's growth. Also, as a more obvious fact, the roots of a plant anchor the plant, essentially to keep it from blowing away in the wind.
Plants have several things that help to protect it. They have cell walls in their cells, which gives it rigidity and structure. They also have cellulose for strength.
There structures that help to grow new plants, like potatoes and ginger.
