A tiny cell that can grow into a new fern?
The tiny reproductive cells of ferns are known as spores. These sling to the underside of the fern's leaves until they are ripe, at which time they are released. Some fall to the ground near the fern while others blow on the wind and start new ferns in other locations.
Is a carnation a fern?
No, a carnation is not a fern. Carnations belong to the genus Dianthus in the Caryophyllaceae family, while ferns belong to the division Pteridophyta and reproduce via spores. They have different reproductive structures and evolutionary histories.
What type of plants use cones as reproductive structures?
All gymnosperms have cones as reproductive structures.
What are the black dots on ferns from?
The 'black dots' (or 'brown dots') on the underside of fern fronds are reproductive structures. They are called sori(the singular is sorus). Within the sorus is a central column (columella), covered by a hard cover, the indusium (the cover you see and call the black dot). Sprouting beneath the indusium (ferns usually have indusia, but not always) and attached to the columella are sporangia, spore-bearing capsules. The fern is the spore-bearer, the sporophyte stage of the fern life cycle.
What are some androgynous plants?
Some androgynous plants include certain species of ferns, such as the bird's nest fern (Asplenium nidus), and certain species of mosses and liverworts that exhibit characteristics of both male and female reproductive structures on the same plant. Additionally, some species of fungi can also be considered androgynous due to their complex reproductive structures.
What does Fern prothallia sporangia mean?
Fern prothallia are small heart-shaped structures that produce reproductive structures called sporangia. Sporangia are responsible for producing spores in ferns, which can develop into new fern plants.
Where are the antheridia and archegonia found in ferns?
Antheridia, the male reproductive structures, are typically found on the underside of fern leaves. Archegonia, the female reproductive structures, are usually found near the tips of young fern leaves.
What is the shape of prothallium?
The prothallium of ferns is typically flat and heart-shaped, with a thin and delicate structure. It is the gametophyte stage in the life cycle of a fern that produces the reproductive structures.

Where are the spore bags found on the fern?
The spore bags, also known as sporangia, are found on the underside of fern leaves, typically clustered in structures called sori. These sori are often arranged in a linear or circular pattern, depending on the fern species. The sporangia contain spores, which are reproductive cells that will eventually develop into new fern plants.
What is the major difference between fern with the fern allies?
The major difference between ferns and fern allies is their reproductive structures. Ferns reproduce through spores produced in clusters called sori on the underside of their fronds, while fern allies reproduce through strobili or cones. Additionally, ferns have true roots, stems, and leaves, whereas fern allies lack true roots and leaves.

Fronds grow from what fern structures?
rhizomes
What is the male reproductive structures of a pea plant?
The male reproductive structures of a pea plant are called the stamen
