Source sentences:
text: Most ferns produce spores on the underside or margin of their leaves.
text: Because the fern reproduces by spore and spores only contain half the chromosomes necessary to produce a mature fern, the fern undergoes an intermediate reproductive stage.
text: A fern (Polypodiopsida or Polypodiophyta) is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers.
text: Although ferns sometimes reproduce using spores, rhizomes also aid reproduction following harsh winters that cause the fronds to die.
text: Instead, ferns procreate through their spores, which open up when they're ripe and spray outward to spread.
text: Using fertilizers rich in nitrogen will promote healthy frond growth, while high phosphate fertilizers will help the fern produce more spores for propagation.
text: Instead, ferns propagate via spores, which are reproductive units that look like small dots on the undersides of the fronds.
text: Ferns and Other Seedless Vascular Plants Ferns, club mosses, horsetails, and whisk ferns are seedless vascular plants that reproduce with spores and are found in moist environments.
text: The distinctive features of ferns are that they reproduce through spores and have neither seeds nor flowers.
text: Ferns reproduce primarily through the use of spores instead of producing flowers to propagate.
text: Unlike flowering plants, ferns produce spores on the back of the fronds that when planted in damp soil create the prothallia, which are flat, green heart-shaped structures that produce sexual organs to create new ferns when fertilized.
text: The fern grows at 3.5 to 5 cm per year and produces spores at the age of about 20 years.
text: Also, many ferns are apomictic; that is, they produce spores with the same number of chromosomes as found in the sporophyte, and new sporophytes arise directly from cells of the gametophyte without the need for gametes or fertilization.
text: Ferns do not flower or produce seed; they produce spores that fall to the ground and become bodies that split into male and female organisms.
text: Instead of producing seeds from flowers, ferns produce spores from their leaves.
text: In the first stage, ferns produce spores -- tiny, dust-like particles -- in brown spore cases on the undersides of their leaves.
text: Ferns produce spores on the backs of their fronds in cases called sporangia.
text: Ferns produce spores that form a fingernail-sized, flat, heart-shaped leaf horizontally on the ground when germinated.
text: Whisk ferns (Psilotales) have no roots, greatly reduced leaves and spore producing organs that are borne on short lateral branches; all other ferns produce spores on their leaves.
text: Ferns reproduce by spores rather than by seeds.
text: Ferns reproduce by spores.
text: Ferns do not have seeds or plants and instead they reproduce by spores.
text: Ferns do not have seeds or plants and instead they reproduce by spores.
text: They reproduce by spores formed on the underside of the leaf or in special fronds.
text: These ferns have green fronds with yellow midribs and reproduce via spores located at the tip of each frond.
text: Ferns reproduce using spores rather than seeds.
text: Instead, ferns procreate through their spores, which open up when they’re ripe and spray outward to spread.
