A stem has several functions, including support, conducting water, storing water, producing food and facilitating asexual reproduction. The stem connects the plant's leaves and flowers to its roots. Along with water, the stem carries products from photosynthesis and nutrients to the roots and leaves. It engages in food production through photosynthesis, and it also stores the products made during photosynthesis.
The stem of a plant is characterized by its buds, leaves, nodes and internodes. The bud is an embryonic part of the stem that may differentiate into a flower, a leaf or both. Buds or leaves extend from the node of the stem. The internode is the point between two nodes. Plant stems may grow above or below the ground. When they grow above ground, they are aerial stems. Those that grow below ground are referred to as subterranean stems. Various forms of aerial stems exist, including runners, offshoots, crowns, stolons and spurs. Subterranean stem types include corms, tubers, rhizomes and bulbs. The basic shape of the stem is cylindrical. A stemless or acaulescent plant only has flowers or leaves present. A culm is a stem found in grass plants such as corn and rice. Plant stems can differ in terms of texture and direction. Textures include woody, herbaceous and suffrutescent. A stem's direction may include twining, creeping, prostrate, climbing, erect, decumbent and ascending.Learn More
Strawberry plants can reproduce through sexual reproduction with fruit and seed, as well as through asexual reproduction by sending out runners to create new plants, according to Garden Guides. Runners, also called stolons, are sent out from the crown of a strawberry plant along the ground. Nodes begin to appear on each stolon at set intervals. Each of these nodes is capable of becoming a daughter plant the following season.Full Answer >
Like a standard three-leaf clover, a four-leaf clover is entirely green in color, has a stem approximately 2.8 inches long and leaves between 0.6 and 0.8 inches wide. Four-leaf clover leaves spread evenly around the stem, with the leaf tips forming the arcs of a circle.Full Answer >
A taproot is a large main root that comes off of the stem and has many smaller lateral roots; a fibrous root system has many roots of the same size that break off into small lateral roots. Dandelions, poison ivy and carrots are all examples of taproots; sweet potatoes are the fleshy part of a fibrous root.Full Answer >
