Question

Question 25 3 pts A botanist discovers a new species of plant in a tropical rain forest. After observing its anatomy and life cycle, she notes the following characteristics: no xylem or phloem, alternating multicellular gametophyte and sporophyte generations with the gametophyte dominant, and no seeds. This plant is probably most closely related to O flowering plants. Oferns. O charophytes. O mosses. green algae.

Answer 1

Option D - Mosses

Most plants have xylem and phloem and are known as vascular plants but some more simple plants, such as mosses and algae, do not have xylem or phloem and are known as non-vascular plants.The sporophyte generation is dependent on the photosynthetic gametophyte for nutrition. Cells within the sporangium of the sporophyte undergo meiosis to produce male and female spores, respectively.The sporophyte is the dominant generation, but multicellular male and female gametophytes are produced within the flowers of the sporophyte. ... Mosses are heterosporous, which means they make two distinct types of spores; these develop into male and female gametophytes.
