Make a complete moss life cycle with the following phases and structures. 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 place
After following the life cycle of an unknown plant species, you determine it's life cycle in the
following order: sporophyte -> meiosis -> gametophyte -> gametes -> double fertilization -> diploid
zygote. Which plant group would you place this species?
O pteridophyte
O basidiomycete
O bryophyte
angiosperm
O gymnosperm
