WebSporangia bearing leaves are called sporophylls. 9. Spores on germination develop into gametophyte which is haploid, multi-cellular, green and an independent structure. 10. develops multi-cellular sex organs. The male sex organ is called antheridium and the female sex organ is calledarchegonium. 11. Sex organs have a sterile jacket. 12. Leaves that bear sporangia are called sporophylls. If the plant is heterosporous, the sporangia-bearing leaves are distinguished as either microsporophylls or megasporophylls. In seed plants, sporangia are typically located within strobili or flowers. Cycads form their microsporangia on microsporophylls … See more A sporangium (PL sporangia; from Late Latin, from Ancient Greek σπορά (sporá) 'seed', and ἀγγεῖον (angeîon) 'vessel') is an enclosure in which spores are formed. It can be composed of a single cell or can be multicellular. … See more In some phyla of fungi, the sporangium plays a role in asexual reproduction, and may play an indirect role in sexual reproduction. The sporangium forms on the sporangiophore … See more • Archegonium • Antheridium • Spore formation See more In mosses, liverworts and hornworts, an unbranched sporophyte produces a single sporangium, which may be quite complex morphologically. … See more A columella (pl. columellae) is a sterile (non-reproductive) structure that extends into and supports the sporangium of some species.

Lab 9:VASCULAR PLANTS: Seedless Vascular Plants (Pterophytes)
WebSporophyll is the leaf that bears sporangia. In ferns, the sporophylls are the normal foliage leaves, but in other plants the sporophylls are modified and arise in specialised structures called cones. Most plants produce spores. of two different size-small microspore and large megaspore. The sporophyll bearing these are called microsporophyll ... WebThe leaves in pteridophytes are small (microphylls) as in Selaginella or large (macrophylls) as in ferns. The sporophytes bear sporangia that are subtended by leaf-like appendages called sporophylls. In some cases sporophylls may form distinct compact structures called strobili or cones (Selaginella, Equisetum). Suggest Corrections. robert c fields

Sporophyll (2n) (sporemeans "spore" and phyllmeans "leaf") The sporophyllis a spore-bearing leaf. Because it is a sporophyte organ, the sporophyllis diploid (2n). The sporophyll grows clusters of specialized 2n structures called sporangia. Sporangium (2n) WebThe sporangia bearing leaves are called sporophyll. Most of the plants produce only one type of spore either microspore or megaspore (homosporous). In some plants both microspore and megaspore are produced (heterosporous). Spores give rise to gametophytic generation called prothallus, which is short lived and independent. robert c ferris
