What group do angiosperms have the closest relationship to? Which of these was the major plant group during the period when dinosaurs dominated the animal kingdom? gymnosperms During the Mesozoic, gymnosperms and dinosaurs were dominating. This is a picture of a,
- Charophyceans are the most closely related green algae to plants.
- Approximately million years ago, plants developed from green algae.475 million years ago, plants emerged from green algae.
- Examples of seedless plant species Ferns Horsetalk Club mosses The are the current plants most comparable to the first plants that produce gametangia.
Bryophytes, such as mosses, are the present plants most akin to the first plants that produced gametangia. Which of these features do algae and seed plants share? development of vascular tissue embryos inside gametangia chloroplasts in roots and stems and pollen Both algae and seed plants have chloroplast-containing cells.
Plants without seeds include Nonvascular plants, such as mosses, liverworts, and hornworts, and vascular plants, such as lycophytes, ferns, horsetails, and whisk ferns, are examples of seedless plants._. charophytes are the closest algae cousins of terrestrial plants. These green algae and plants have several similar characteristics.
Which of the following characteristics was most crucial in allowing the earliest plants to migrate onto land? The formation of sporopollenin to prevent zygotes from drying out. Without sporopollenin, terrestrial plant reproduction would have been far more difficult.
This was one of the first issues that needed to be resolved before plants could take use of the available habitats on land. Gametophytes are the major stage in the life cycle of bryophytes and are typically bigger than sporophytes. Mosses’ sporophytes consist of a foot, a seta, and a sporangium. The foot is implanted in the gametophyte, from which it collects nutrition.
The seta or stalk delivers nutrients to the sporangium, which is responsible for spore production. Gametophytes are anchored to a substrate by rhizoids, which mimic the roots of vascular plants. Rhizoids are not vascular structures Which of these is the sporophyte stage of the moss life cycle? ______ make sperm in moss.
Moss-produced sperm must in order to reach an archegonium. In mosses, gametes are generated by _, whereas ferns produce gametes by, cells inside a sporangium undergo in the moss life cycle to create spores. diploid; meiosis; haploid In mosses, gametes are generated by _, whereas ferns produce gametes by,
Where do the antheridia of ferns develop? on the bottom of the gametophyte The prominent feature of a fern plant is its, distinguishes the majority of bryophytes, such as mosses, from all other plants. absence of real leaves and roots Of contrast to bryophytes, the major stage of the life cycle in vascular plants is the,
- Sporophyte In vascular plants, the diploid sporophyte generation is dominant; in bryophytes, the haploid gametophyte generation is dominant.
- What evolutionary advance enabled tall plant growth? lignified vascular tissue Which of the following is created by meiosis in plants? a.
- Haploid gametes b.
- Haploid sporophytes c.
diploid gametes d. haploid spores e. diploid spores Which of the following does not indicate that charophytes are the most closely related algae to plants? Which of the following plant features is lacking in their nearest cousins, charophyte algae? successive multicellular generations Microphylls are present in which group of plants?
What traits do algae and vegetation share?
Algae, like plants, have chlorophyll and produce nourishment through photosynthesis. Red and green algae, euglenids, and dinoflagellates are types of algae.
Seed-bearing plants have two essential traits. They have vascular tissue and reproduce via pollen and seeds. In addition, the body plans of all seed plants consist of roots, stems, and leaves.
What three features do plants and algae share?
The terms in this set (27) have three features with green algae and land plants. They make their own food through photosynthesis, have chlorophyll-containing eukaryotic cells, and, Have cell walls composed of cellulose.
