In which group of plants are both the sporophyte and gametophyte free- living?
In seedless vascular plants, such as ferns, both the sporophyte and gametophyte stages are free-living. The sporophyte is the dominant stage, while the gametophyte is usually a small, independent structure that produces gametes.
Which generation of mosses are the photosynthetic?
The gametophyte generation of mosses is photosynthetic. The gametophyte is the predominant and independent stage in the moss life cycle that carries out photosynthesis to produce energy for the plant.
What plant group is characterized by dominant sporophyte vascular tissues and seeds exposed on cones?
The plant group characterized by dominant sporophyte vascular tissues and seeds exposed on cones is the gymnosperms. This group includes plants like conifers, cycads, and ginkgo trees. Gymnosperms do not produce flowers and their seeds are not enclosed within a fruit.
What are the three main groups of plants?
The three main groups of plants are non-vascular plants (e.g., mosses), seedless vascular plants (e.g., ferns), and seed plants (e.g., flowering plants). Each group has unique characteristics related to reproduction, structure, and life cycle.
What is an angiosperm?
APEX - A plant that produces seeds w/ protective covers

What types of algae show a distinct alternation of generations?
Some types of algae that show a distinct alternation of generations are members of the green algae group, such as Ulva and Spirogyra. These algae have a haploid gametophyte generation and a diploid sporophyte generation. The gametophyte generation produces haploid gametes that fuse to form a diploid zygote, which develops into the sporophyte generation that produces haploid spores.
Which generation of mosses are the photosynthetic?
The gametophyte generation of mosses is photosynthetic. The gametophyte is the predominant and independent stage in the moss life cycle that carries out photosynthesis to produce energy for the plant.

What is a example of a nonvascular?
mosses and liverworts.Sillypinkjade says:The liverwort- gametophyte has a flattened leaf-like structure called a thallus.The mosses- are the largest group of non-vascular plants.Bryophytes-include the non-vascular mosses and liverworts.*In the mosses, spores are produced by the sporophyte*;)"Just giving info on what you don't know"what is thallus

Are bryophytes the simplest group of plant?
Yes, bryophytes are considered the simplest group of land plants. They lack vascular tissue for transporting water and nutrients and do not have true roots, stems, or leaves. Bryophytes include mosses, liverworts, and hornworts.
How does red algae reproduce?
Red algae reproduce through a process known as alternation of generations. This involves the alternation between a diploid sporophyte generation and a haploid gametophyte generation. The sporophyte produces haploid spores through meiosis, which then develop into new gametophytes. The gametophytes then produce haploid gametes through mitosis, which fuse to form a zygote and restart the cycle.
Do the flowering plants make up the smallest group of all types of plants?
No, the flowering plants (angiosperms) are actually the largest group of plants, with over 300,000 species. Mosses and liverworts (bryophytes) represent a smaller group of non-flowering plants.
