Some plants are able to reproduce without releasing seeds asexually using a specialized stem called a rhizome or by releasing spores. Bulb plants, such as Persiant violets, crinum lilies and wood hyacinths, are just a few examples of plants that reproduce asexually.
In bulb plants, asexual reproduction occurs when a bulb on the plant splits to create multiple bulbs. The smaller bulbs, called bulblets, separate from the main plant and eventually become new plants. Unlike traditional seed reproduction, newly sprouted bulb plants carry the very same genetic code as their parent plants.
Plants that are able to reproduce without seeds have rhizomic stems, which grow beneath the ground. The stems grow parallel to the soil and several inches from the main stem. From there, new roots start to develop and form new plants. Examples of some plants that reproduce this way include Venus flytraps, Chinese lanterns and hops.
Spores are small reproductive cells, and plants that use this method of reproduction release millions of tiny spores into the air. The spores are carried by the wind, and once they land in environments perfect for growth, a basic root system starts to form, creating a new plant. Some plants that reproduce this way are the floral fern, the haircap mass and the rockcap moss.Learn More
Ferns reproduce through their spores, which are produced in very small spots called sori. Each sorus consists of numerous tiny, spherical granules that contain sporangia. Once the sporangia mature, they burst and release spores into the wind, and this is how new ferns emerge.Full Answer >
Seeds, when compared to spores, have distinct advantages due to their hard outer shells and internal structures called endosperms, which provide essential nutrients for enclosed seedlings. Seeds are found only in flowering plants and gymnosperms. They contain embryos deep within their centers, which are surrounded by a sack of nutrients and minerals enclosed by a tough protective outer shell that protects the growing seed from predation and life-threatening exposure to the elements.Full Answer >
According to Biosciences for Farming in Africa, sexual reproduction in plants occurs when pollen from a plant's stamen reaches the stigma of a flower. The pollen contains sperm cells while the stigma holds the corresponding eggs. When the two meet, the sperm cells fertilize the egg, creating an embryonic seed that later germinates into a new plant.Full Answer >
Plants either reproduce sexually or asexually, depending on the type of plant. In sexual reproduction, two germ cells, or gametes, fuse to create the beginning of a genetically unique offspring. In asexual reproduction, a plant cell splits in two to create a genetically identical offspring.Full Answer >
