Different Types Of Seed Dispersal By Group 6 Ruth, Joanne, Danish and Nirupan Introduction Plants, unlike humans, have many different types of reproduction methods: seeds, spores, stem cutting and more. We will explain to you about different types of reproduction methods other than seeds. - Listen closely as there will be prizes at the end. Reproduction by spores • Unlike seeds, spores are an asexual method of reproduction in plants. • Scientists believe that, at one time, all plants were actually spore-bearing. • However, plants began to form seeds rather than spores. • Primitive plants such as mosses, algae and ferns now rely on spores to reproduce. Layering • These plants produce long, drooping canes. When the canes make contact with the soil, they Begin to take root and form new plants. • Example of plants which uses this technic: • Blackberries and multiflora roses • Budding • A bud like outgrowth is formed on one side of the parent cell and soon it separates and grows into a new plant. • Example of plant that uses this technic: yeast • Vegetative reproduction • Many plants have the ability for vegetative propagation. • Meristematic cells capable of cellular differentiation are present in many plant tissues. • • • • • This is a mulberry tree that reproduces by the process of vegetative propagationvegetative propagation. Suckers • Some plants produce new plant shoots from their root systems. • This form of vegetative reproduction is called suckering. • The new shoots are called suckers. Banana trees reproduce by suckers. Grafting • A form of asexual plant propagation. • Consists of connecting two pieces of living plant tissue in a way that allows the parts to grow and develop as a single plant. • A piece of stem or shoot with dormant buds, known as the scion, is the part that will grow and develop with branches. Plantlets and Growth From Damage • Plantlets • Plantlets are new, small plants that grow on the leaf edges of a parent plant. Duckweed reproduces by plantlets. • Growth from Damage • Tree stumps often produce new shoots; broken leaves can also take root. Runners • Plants like strawberry produce stems that grow along the ground, creating new plants at intervals along the runner, complete with roots and leaves. • The runners are also called stolons. Strawberry plant Stem Cutting • Forcing a cutting to produce roots is the most common method of propagation. • This method can used on leaves or stems, depending on the type of plant. • This method usually works better with herbaceous plants but can be successful with woody plants as well. This is a geranium that reproduces by stem cutting. Quiz Time!!! Q1) What is another name for runners? Ans: Stolons Q2) Is spores a sexual or asexual way of reproducing? Ans: asexual reproduction Q3) How do duckweeds reproduce? Ans: Plantlets Conclusion In conclusion, there are many types of reproduction methods for plants. For example, spores, stem cutting etc. Credits and Sources • Wikipedia, eHow.com, gardenguides.com, Google and Yahoo • Tom Clark, Mount Holyoke College Botanic Garden, Horticulture Identification and Judging Contest, Plant Propagation THANK YOU FOR YOUR KIND ATTENTION!!!!
