The Reproductive System – Notes

How Do Organisms Reproduce? – Reproduction in Unicellular and Multi-cellular Organisms

 Organisms like Hydra reproduce by building. They use the regenerative cells for reproduction in the process of budding. A bud develops as an outgrowth due to repeated cell division at a specific site on the hydra. Each of these buds develops into a new individual.

Vegetative propagation is a process of reproduction by which new plant species develops through roots, stem, and leaves of the parent plant.

Spore formation can be observed in organisms like the rhizopus. Rhizopus is composed of thread– like structures called hyphae. The tiny blob-on-a-stick structure on each hypae contains spores that are responsible for reproduction.

Plant Tissue Culture is a method used to propagate plants under hygienic conditions. It is often used to produce clones of a plant.
