Chapter 28, Problem 6IQ
Summary Introduction
To explain: Three different mechanisms by which increased size and complexity have evolved in chlorophytes.
Introduction: Green algae can be differentiated into two main types of groups: chlorophytes that includes species of more than 7,000 and charophytes that includes those algae that are related closely to the plants. The chlorophytes lives mostly in fresh water, but some of them are terrestrial and many species are marine habitat.

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
