Students will learn about two types of plant propagation — seed planting sexual and stem cuttings asexual and recognize the genetic differences in these processes, as well as the advantages and disadvantages of each method. Plants provide perfect living specimens for comparing sexual reproduction AKA propagation and asexual reproduction.
Focusing on plants that provide edible products fruits, vegetables, flowers, etc. This information is contained in the small sometimes microscopic embryo inside of the seed. The development of a seed can be attributed to the flower, pollination and fertilization Cutting in plants asexual reproduction interactive see attached student reading Seed to Seed Corn is common agricultural plant grown in Minnesota, and many other regions of the United States, that can be used to demonstrate the seed production process.
The steps are described below. Students will research the flowers of vegetable and fruit plants and illustrate how the genetics from the parent plants produce a new seed, which will develop into a new plant. Plants also have the ability to reproduce without utilizing the genes from parents.
This process of reproduction is called asexual reproduction. Plant scientists routinely refer to asexually reproduction as vegetative propagation. In asexually propagation, a complete plant can be regenerated from a severed piece of stem, root, a bud, leaf or even a small group of certain plant cells. The phenomenon of asexually propagation can be easily demonstrated in a classroom using stem cuttings.
Students cut off a small portion of the stem of a plant see Stock Plant lists for examples. When this cutting removed portion of the plant is placed in soil or water and provided with light — new roots will be developed and a new plant will be on its way!
are most likely to develop at a stem wound that is in firm contact with moist
Cutting in plants asexual reproduction interactive. When a plant is wounded, hormones called auxins collect briefly around the wound and cause cell division so that it begins to form embryonic root tissue. This tissue develops into fully functioning roots and the plant will continue to grow leaves, stems and additional plant parts identical in genetic make-up to the parent plant.
The processes of planting seeds and also taking stem cuttings are easy and fun activities Cutting in plants asexual reproduction interactive students to complete.
The plants that result are perfect for inquiries, discussions, and experiments on genetics and the environment. We welcome your feedback!

Jeweler size plastic bags (these can be purchased from craft stores, online or might even be free from a Session 2: Asexual Reproduction – Stem Cuttings.
Title of Lesson: Propagating Plants by Cuttings (Lesson 3). Objectives: At Define the following terms: asexual reproduction, parent plant, and rooting medium. It takes 3–4 years from taking the cutting until the plant is mature enough for the first harvest.
Many plants can reproduce this way naturally, but vegetative. In the interactive Making a transgenic plant, the third step shows.
