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
Green algae are believed to be the ancestors of the bryophyte. Cite four distinct lines of evidence to support this belief.
