Producing two kinds of spores unlike each other.
lifecycle in which there are two types of spores produced. Male spores germinate into microgametophytes which produce sperm, and female spores germinate into megagametophytes which produce eggs.
Referring to plants that produce microspores and megaspores, which give rise, respectively, to sperm-producing and egg producing gametophytes
( het-ur- os-pur-us) Referring to plants in which the sporophyte produces two kinds of spores that develop into unisexual gametophytes, either female or male.
producing two kinds of spores (male and female, or microspores and megaspores). cf. homosporous.
having two types of spores: megaspores and microspores
Producing two morphologically distinct types of sporangia (megasporangia and microsporangia) that produce two distinct types of spores (megaspores and microspores), which develop into separate male and female gametophytes (i.e., unisexual gametophytes). Heterosporous plants covered in Bio 240 Lab include Selaginella, heterosporous ferns, "gymnosperms," and flowering plants.
The formation of more than one sort of spore, usually microspores and megaspores in ferns and seed plants, giving rise to distinct male and female gametophyte generations.
Describing plants producing both microspores and megaspores.
(het´ er os´ por us) • Producing two types of spores, one of which gives rise to a female megaspore and the other to a male microspore. Heterosporous plants produce distinct female and male gametophytes. (Contrast with homosporous.)
Having two kinds of spores, usually differing in size.
Producing two different sizes or kinds of spores. These may come from the same or different sporangia, and may produce similar or different gametophytes. Contrast with homosporous, and compare with heterosporangiate.
