Verified step by step guidance1
Identify the closest living algal relatives of land plants, which are the charophytes, a group of green algae.
Understand that both land plants and charophytes share certain structural and biochemical features due to their common ancestry.
Recognize that rings of cellulose-synthesizing complexes are a shared feature, as both groups use these structures to synthesize cellulose for their cell walls.
Acknowledge that the formation of a group of microtubules, known as the phragmoplast, occurs during cell division in both land plants and charophytes, facilitating the construction of the cell plate.
Note that sporopollenin, a durable polymer, is present in the zygotes of charophytes and the spores of land plants, providing protection against desiccation, and that the structure of flagellated sperm is similar in both groups when present.
