A plant’s stem serves as the support structure for its above ground components and as a conduit through which water and nutrients can travel. When a stem is green due to the presence of chlorophyll, it also produces food. In some plant species, the stem stores energy or food for future use.Continue Reading
The stems of plants vary widely, depending on the lifestyle, growth habit and location of the plant. For example, sunflowers have long, thick stems that lift the flower heads up to 6 feet in the air. By contrast, the stems of some vines are long, flexible and feature extensions called tendrils that help them ascend trees. Some stems, such as stolons, lie horizontally, and this occurs when a plant undergoes vegetative propagation, which is a method of asexual reproduction.
Humans and other animals rely on the stems of plants as well. Humans use stems as food, a source of fibers for textiles and as a fuel for fires. Many plants have thorns, which are modified stems that provide nutrients and protect from herbivores. Humans use the stems of some plants, such as celery stalks and broccoli, as food. Animals also consume stems as food, and some species use the hollow interiors of plant stems as a habitat.Learn more about Botany
A plant's organ system works with the roots anchoring the plant and absorbing water and nutrients, while the shoots transfer the nutrients to the leaves, which transfer light into energy via photosynthesis. A plant’s roots, leaves and stems, the three basic plant organs, work together to allow the plant to function. The plant’s shoot system, which includes the leaves, stems, and flowers, is divided into two sections: the non-reproductive portion and the reproductive portion. The reproductive portion includes the flowers and fruit. The non-reproductive portion includes the leaves and stems.Full Answer >
When the abscission layer of a plant grows, it cuts off the circulation of nutrients, sugar and water to the leaves, which causes the chlorophyll that gives the plant its green color to disintegrate and makes carotene shine through. The result is the yellow-colored leaves that are found on maple and other trees, such as birch and aspen, in the fall.Full Answer >
Sunlight and water both support the production of chemical nutrients inside the cells of a plant. Sunlight is critical in the process during which water molecules are broken apart inside the pigmented cells of the plant. Water also transports the nutrients throughout the plant and supports its structure.Full Answer >
The two main functions of roots are to deliver water and nutrients to the plant or tree and provide an anchor that keeps the plant or tree in the soil. Roots are generally the first part of any plant that emerges during germination.Full Answer >
