Spores are produced by bacteria, fungi, algae, and plants. Bacterial spores serve largely as a resting, or dormant, stage in the bacterial life cycle, helping to preserve the bacterium through periods of unfavourable conditions.

In plants, spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte. In some rare cases, diploid spore is also produced in some algae, or fungi. [6]

2019年3月26日 · In a plant’s life cycle, the spore-producing phase is called sporophyte. There are two stages of reproduction in plants: sexual and asexual. Through the process of meiosis and fertilization, the alternation of generation segregates these two …

Examples of plants that reproduce from spores and there characteristics including a final summary of the classifications of plants GCSE revision notes.

2024年7月5日 · In plants, particularly non-vascular plants like mosses and ferns, spores are a crucial part of their life cycle. These plants produce spores in sporangia located on the undersides of their leaves or within specialized structures, which …

Plants employ two primary reproductive strategies: spores and seeds. Seeds are the prevailing method among flowering plants (angiosperms) and cone-bearing plants (gymnosperms). On the other hand, simpler plants lacking flowers, fruits, or …

Among plants, spores are the reproductive agents of asexual generation. They are produced by the sporophyte generation and give rise to the gametophyte (gamete-bearing) generation. Spores are most conspicuous in the seedless plants, a group that includes liverworts, mosses, and ferns. The spores are carried in cases called sporangia.

Pteridophytes are vascular plants that produce spores, such ferns, horsetails, clubmoss, and spikemoss. Pteridophytes are distinguished from other spore-producing plants, bryophytes, by their vascular tissue.

2021年8月19日 · Spores are reproductive cells in plants; algae and other protists; and fungi. They are typically single-celled and have the ability to develop into a new organism. Unlike gametes in sexual reproduction, spores do not need to fuse in order for reproduction to take place. Organisms use spores as a means of asexual reproduction.

2023年2月2日 · Sporulation or spore formation is the process of producing spores from the actively dividing (vegetative) cells. They are commonly found in bacteria, fungi, protozoa, and some plants such as ferns and mosses. The term ‘spore’ comes from the Greek word for seed.
