Examples of plants with contractile roots include lilies, tulips, and some species of Asparagus. These roots have the ability to contract, allowing the plant to pull itself deeper into the soil. This adaptation helps the plant anchor itself securely and access nutrients from deeper soil layers.
Some herbaceous dicots and monocots have contractile roots that pull the plant deeper into the soil. Many lily bulbs are pulled a little deeper into the soil each year as new sets of contractile roots are developed (Fig. 5.13). The bulbs continue to be pulled down until an area of relatively stable temperatures is reached. Plants such as dandelions always seem to have the leaves coming out of the ground as the top of the stem is pulled down a small amount each year when the root contracts. The contractile part of the root may lose as much as two-thirds of its length within a few weeks as stored food is used and the cortex collapses. Figure
A specific type of vacuole, called a contractile vacuole expels excess water from many fresh water protists.
Fleshy roots are classified based on their structure and function. They can be classified as storage roots, which store energy and nutrients for the plant, or as contractile roots, which help to anchor the plant in the soil and pull the plant deeper into the ground. Examples of fleshy roots include tubers (e.g. sweet potatoes), rhizomes (e.g. ginger), and corms (e.g. taro).

because they have their own special functions
MATLAB can be used to find the roots of a given equation by using the built-in functions like "roots" or "fzero". These functions can solve equations numerically and provide the values of the roots. By inputting the equation into MATLAB and using these functions, the roots can be easily calculated and displayed.

The roots are essential parts of a plant. Their major functions include anchorage in soil, storage of energy resources and absorption of water and minerals from the soil.

Two functions of roots are to absorb water and nutrients from the soil.

Muscle tissue is predominantly composed of contractile cells that allow for movement and force generation in the body. There are three types of muscle tissue: skeletal muscle, smooth muscle, and cardiac muscle, each with specific functions and characteristics. Muscle tissue is responsible for functions such as body movements, maintenance of posture, and generation of heat.
