What is a stem that grows along the surface of the ground?
In botany, stolons are stems which grow at the soil surface or just below ground that form adventitious roots at the nodes, and new plants from the buds. Stolons are often called runners.
What is the term for the stems of the plant that spread along the ground and can form new plants?
Rhizomes are modified stems running underground horizontally. They strike new roots out of their nodes, down into the soil. They also shoot new stems up to the surface out of their nodes. This rhizome activity represents a form of plant reproduction. These underground plant parts also store nutrients.
What do we call a stem that grows along the ground or in the air and forms a new plant at its tip?
Bulbils
Bulbils are axillary buds that have become fleshy and rounded due to storage of food. They become detached from the plant, fall on ground and develop into a new plant. Cladodes are green branches of limited growth (usually one internode long) which have taken up the functions of photosynthesis.
What are underground stem called?
Rhizomes are underground stems which grow beneath the surface of soil; they are frequently fleshy and serve as organs of food storage. Sometimes the rhizomes are condensed into solid swollen forms which are then known as corms. The tubers are also underground parts, which may either be modified roots or stems.
What do emergent plants look like on land?
The emergent plants resemble shining clubmoss; bog moss, however, produces true flowers. On land, the leafy stems can be upright, or run along the ground and then turn or branch upwards, to at most 2 ft (60 cm).
What kind of plant has small white flowers?
Buckhorn plaintain is also known as English plantain. Its thin leaves have three ribs and are all located in a basal rosette. Tiny, white flowers develop in a short, fat flower head at the tip of a long, grooved stalk.
How are the leaves of an exotic plant arranged?
Leaves are compound and arranged alternately along the stem. The leaf has three leaflets with two leaflike stipules at the base of the leaf stalk. Each stem may be two feet in length and usually grows flat on the ground. Seeds develop in pods.
How tall does an emergent plant grow in a marsh?
Grow from rhizomes to form clumps of slender, smooth, jointless stems arising above water or lower marsh plants. Rarely grows submersed. Many species are tall, growing to 10 ft (3 m), while others are as short as 6 in (15 cm).
