Why do ferns and mosses typically live in moist conditions?
The vascular tissues in the more advanced ferns and “fern allies” are made up of xylem and phloem, which conduct water, nutrients, and food throughout the plant body. Their flagellated sperm must swim through water to reach the egg. So mosses and liverworts are restricted to moist habitats.
Why must ferns live in moist environments?
The movement of spores requires a thin film of water. This is the main reason for ferns living in a moist environment. Water helps the spore to travel from Antheridium to Archegonium. In fact, all types of ferns and other related species need some sort of moisture to reproduce and grow.
Why must mosses and ferns live in moist environments quizlet?
Why do ferns, club mosses and horsetails need a moist environment? because the plants release spores into their surroundings, where they grown into gametophytes. When the gametophytes produce the egg and sperm cells, there must be enough water for the sperm to swim to the egg.
In what ways do ferns club mosses and horsetails differ from mosses?
how do these characteristics differ fro those of mosses? Ferns, horsetails and club mosses have dominant sporophytes; mosses have dominant gametophytes. Ferns, horsetails and club mosses have vascular tissue and true roots and stems; mosses do not. Mosses produce spores in capsules.
What two characteristics do ferns and club mosses share?
6. Ferns, club mosses, and horsetails share two characteristics: they have true vascular tissue: a system of tubelike structures inside a plant that water, minerals, and food move through.
What characteristics do mosses and ferns share?
They’re Both Nonflowering Plants Ferns produce spores on the undersides of their fronds in cases called sporangia, and mosses produce their spores in capsules that are borne on the ends of stalks.
Which one of the following is a major difference between mosses and ferns?
Which one of the following is the major difference between mosses and ferns? Ferns lack alternation of generation while mosses show the same. Mosses are facultative aerobes while ferns are obligate aerobes. Vascular bundles of ferns show xylem vessels while those of mosses lack it.
What is the result of Heterospory?
They develop archegonia that produce egg cells that are fertilized by sperm of the male gametophyte originating from the microspore. This results in the formation of a fertilized diploid zygote, that develops into the sporophyte embryo.
What is the difference between algae and ferns?
Species of Plants: Algae and ferns are both examples of plants, but both have major differences in their anatomy. Algae lack many of the adaptations of land plants, such as xylem and phloem, while ferns use seeds to reproduce.
What are the similarities between gymnosperms and angiosperms?
Both have leaves, stem, and roots. Hint: Both have similar basic parts and structure of the plants, thus making it similar in structure except the flowers because the gymnosperm is found to be more simple as compared to the angiosperm that is more advanced like they produce fruit to protect seed.
What are the similarities between monocots and dicots?
Both monocots and dicots have stamens with two pairs of pollen sacs, male gametophytes of three cells, and female gametophytes made up of seven cells with eight nuclei. Also, the carpel is closed.
What do ferns and gymnosperms have in common?
Both have vascular tissue of a sort, but gymnosperms are heterosporus. Not all ferns have both types of spore. The reproductive parts of gymnosperms are in cones, where ferns have sperm and sorii (grainy dots that are the indusium) on the underside of their leaves.
Why are gymnosperms more successful than ferns?
Compared to ferns, gymnosperms have three additional adaptations that make survival in diverse land habitats possible. These adaptations include an even smaller gametophyte, pollen, and the seed. Gymnosperms are plants that bear seeds that are “naked,” meaning not enclosed in an ovary.
How does the life cycle of gymnosperms differs from that of ferns?
1. In both the groups there is alternation of generations but there is reduction in the gametophytic generation of the gymnosperms. In gymnosperms the gametophyte is reduced and is unlike that of ferns as it is completely dependent upon the sporophyte.
What do gymnosperms have that ferns dont?
Summary : 1. Ferns are flowerless plants that do not have any seeds whereas gymnosperms do have seeds of their own. Ferns have free-living gametophytes whereas gymnosperms don’t.
What is the life cycle of a gymnosperm?
Gymnosperms are vascular plants that produce seeds in cones. Examples include conifers such as pine and spruce trees. The gymnosperm life cycle has a dominant sporophyte generation. Both gametophytes and the next generation’s new sporophytes develop on the sporophyte parent plant.
