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 first generation of mosses starts with germination of spores to develop into gametophyte. The male and female gametophytes produce anthridia and archegonia. Motile antherozoids are released from anthridia and make their way to archegonia through water. The egg inside archegonium is fertilized to form the zygote. The zygote develops into a sporophyte, which remain dependent on the gametophyte.
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 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.

What best describes fits seedless vascular plants?
Seedless vascular plants are a group of plants that have specialized tissues for transporting water and nutrients but do not produce seeds. This group primarily includes ferns, horsetails, and club mosses. They reproduce through spores rather than seeds, and their life cycle typically features a dominant sporophyte generation. These plants thrive in moist environments and play important ecological roles in their habitats.

Are bryophytes the simplest group of plant?
Bryophytes are the simplest land plants because they lack vascular tissues and are usually 1 to 2 cm in height and they need water for their reproductioin and they live in damp places and in them gametophyte generation is dominant.
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.
