Question

Name any 5 units of vegetative propagation? give one example for each​

Answer 1

• Vegetative reproduction (also known as vegetative propagation, vegetative multiplication or vegetative cloning) is any form of asexual reproduction occurring in plants in which a new plant grows from a fragment of the parent plant or a specialized reproductive structure.

• Runners

• Runners, also called stolons, are similar to rhizomes in that they exhibit horizontal growth at or just below the soil's surface. Unlike rhizomes, they originate from existing stems. As runners grow, they develop roots from buds located at nodes or their tips. Intervals between nodes (internodes) are more widely spaced in runners than in rhizomes. New plants arise at nodes where shoots develop. This type of propagation is seen in strawberry plants and currants.
• Bulbs

• Bulbs are the round, swollen parts of a stem that are typically found underground. Within these organs of vegetative propagation lies the central shoot of a new plant. Bulbs consist of a bud that is surrounded by layers of fleshy, scale-like leaves. These leaves are a source of food storage and provide nourishment to the new plant. Examples of plants that develop from bulbs include onions, garlic, shallots, hyacinths, daffodils, lilies, and tulips.
• Tubers

• Tubers are vegetative organs that may develop from stems or roots. Stem tubers arise from rhizomes or runners that become swollen from storing nutrients. The upper surface of a tuber produces a new plant shoot system (stems and leaves), while the bottom surface produces a root system. Potatoes and yams are examples of stem tubers. Root tubers originate from roots that have been modified to store nutrients. These roots become enlarged and may give rise to a new plant. Sweet potatoes and dahlias are examples of root tubers.
• Corms

• Corms are enlarged bulb-like underground stems. These vegetative structures store nutrients in fleshy, solid stem tissue and are typically externally surrounded by papery leaves. Due to their physical appearance, corms are commonly confused with bulbs. The major difference is that corms contain solid tissue internally and bulbs have only layers of leaves. Corms produce adventitious roots and possess buds that develop into new plant shoots. Plants that develop from corms include crocus, gladiolus, and taro.
• Plantlets

• Plantlets are vegetative structures that develop on some plant leaves. These miniature, young plants arise from meristem tissue located along leaf margins. Upon maturity, plantlets develop roots and drop from leaves. They then take root in the soil to form new plants. An example of a plant that propagates in this manner is Kalanchoe. Plantlets may also develop from the runners of certain plants such as spider plants.
