What is true about the life cycle of a land plant? 1. The gametophyte produces spores by meiosis. 2. The life cycle is entirely haploid, so the sporophyte phase does not exist. 3. The sporophyte produces spores by mitosis. 4. The sporophyte produces spores by meiosis. 5. The gametophyte produces gametes by meiosis.

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.

For the list of events below, place them in order to describe the life cycle of the plant, beginning with the germination of a new plant. Then, decide which stages describe the sporophyte stages and which stages describe the gametophyte stages and label each accordingly. Drag the text blocks below into their correct order.
