Note: download the images of Mnium from this link and arrange them in the exact sequence to make the lifecycle. Lifecycle structures with cell division: Meiosis, fertilization within archegonium, capsule (sporangium), spores (n), protonema (n) (Image), male gametophyte (n) (Image), female gametophyte (n) (Image), antheridia (Image), archegonia (Image), sperm, egg, water, zygote (2n), embryo, young growing sporophyte (2n), mature sporophyte (2n) (Image), rhizoids. You can insert the non-image part, using the textbox and fill out the suitable s text. For symbol, click on the shape option and inter in your lifecycle diagram at the required placeFerns differ from mosses in having: O a. There is no separate gametophyte and sporophyte (each plant changes from sexual to asexual). O b. The gametophyte is dioecious (single sex). Oc. The sperm are transported by wind. O d.
