![]() They do not require any other organism for their reproduction process and in a way are self-sufficient. In such kinds of organisms, the majority of the sporangia produces haploid spores. One difference between Conidia and oidia is that the former is formed during unfavourable conditions whereas the latter is formed during favourable conditions. Ii) Oidia- these are also formed at the tip of the body but in the presence of excess food material. I) Conidia- these are formed at the tip of the body. These Aplanospores are further divided into two types- In majority of the pteridophytes all the spores are of similar kinds such plants are called homosporous. Lower fungi and algae like haematococcus and vaucheria are some examples. Ii) Aplanospore- these spores do not show motility and are formed from a part of a vegetative cell. Some of its examples are- Chlamydomonas an algae and Albugo fungi. I) Zoospore- these spores show movement due to the presence of flagella however they lack a true cell wall in them. The spores are single-celled minute structures which may be motile in some case whereas non-motile otherwise. Under suitable conditions, these spores germinate to form a new plant. A spore is typically a single cell surrounded by a thick. Once these spores mature the sporangia burst and these matured spores reach different areas by air, wind and water. In plants, spores are usually haploid and unicellular and are produced by meiosis in the sporangia of diploid sporophytes. Spores are an asexual form of reproduction the plant or fungus doesn't need to mate with another plant or fungus to form these particles. ![]() The stems of such plants contain silica that helps in washing or cleaning of pots, pans, and. These plants produce spores in strobili (formed on fertile shoots) with photosynthetic gametophytes. Spore formation is a form of reproduction in which the reproductive bodies called the spores are present in a sac called the sporangia. Vascular plants (biology definition): plants with vascular tissues, particularly, xylem and phloem for conducting water and integrating food. Gametes thus can be differentiated from these spores which definitely requires fuse with another gamete for reproduction. ![]() This process requires spores, a reproductive cell that is capable of becoming a new plant without undergoing any kind of fusion with any other cell. Hint: Spore formation is an asexual mode of reproduction. ![]()
