Name the features that distinguish the angiosperms from ferns. Angiosperms, when compared to ferns, are flowering and produce seeds. Also, both mosses and ferns show alternation of generation. But, the dominant phase of the life cycle of mosses is the haploid gametophyte generation, while the dominant phase of the life cycle of ferns is the diploid sporophyte generation.
Therefore, this is another important difference between mosses and ferns. They are found contained in a casing, called sporangia, and grouped into bunches, called sori, on the underside of the leaves. Spores look like little dots and may be harvested for fern spore propagation by the intrepid gardener. Ferns produce their spores on the undersides of the leaves fronds.
You may have seen them. They are the brown "spots" or "pads" on the bottom of the leaves. If you have access to a microscope, use it to look at the spores. They are not all big and showy, either.
All flowers, showy and dull, have the same purpose. Flowers produce seeds. Specifically, they produce fruits that contain hardy seeds surrounded by a seed coat. This coat is able to protect the embryo within until conditions are favorable for germination.
These plants also have vascular tissue, which allows water and nutrients to be transported throughout the plant. Flowering plants make up 80 percent of plant diversity on the planet, so there are many examples of flowering plants. In fact, most of the plants you are familiar with produce flowers. While most green plant life is composed of a large number of rather closely-related angiosperms, nonflowering plants are spread across several botanical categories.
You're likely to be the most familiar with gymnosperms. Gymnosperms are a more primitive lineage than angiosperms, and evidence suggests angiosperms actually evolved from gymnosperms. The rest of the nonflowering plants are more primitive than gymnosperms, and they do not produce seeds. These are known as seedless vascular plants and seedless nonvascular plants. Of the nonflowering plants, gymnosperms are the most closely related to flowering plants, and because of that, they are the most similar to them.
Gymnosperms , much like angiosperms, are complex plants with vascular tissue that produce seeds. Mosses: Mosses belong to the phylum Bryophyta. Ferns: Ferns belong to the phylum Pteridophyta.
Mosses: Mosses consist of a lot of leaflets. Ferns: Ferns consist of true leaves and stems. Mosses: Mosses contains multicellular rhizoids. Mosses: Mosses grow up to several centimeters. Mosses: In mosses, the sporophyte depends on the gametophyte. Ferns: In ferns, the gametophyte depends on the sporophyte. Mosses: Mosses consist of male and female gametophytes separately.
Ferns: Ferns contain both male and female gametophytes in the same structure. Mosses: Mosses produce spores in the capsules, which are connected to the gametophytes by stalks. Ferns: Ferns produce spores as clusters underneath the leaves. Mosses: Common hair cap moss, prickly sphagnum, limpr, and club mosses are some examples of mosses.
Ferns: Bracken, silver cloak fern, fishbone fern, leatherleaf fern, and cinnamon fern are some examples of ferns. Both plants are non-flowering plants. Therefore, both of them are seedless plants as well. Both mosses and ferns undergo alterations of generations. That means both are spore-producing plants. The gametophyte is prominent is mosses, but the sporophyte is prominent in ferns.
