Q: How are the Charophyceae related to land plants?
A: The Charophyceae are closely related to land plants, and are considered to be the organisms most closely related to them.
Q: What plant traits are thought to have evolved first in charophyceans?
A: Many of the complex plant traits related to sexual reproduction are believed to have evolved first in charophyceans.
Q: What is the significance of analysis of cpDNA in relation to Charophyceae?
A: Analysis of cpDNA has shown that characteristics of plant chloroplasts evolved first in the Charophyceae, before the Zygnematales diverged from the lineage that lead to Coleochaetales, Charales, and land plants.
Q: What are the groups typically included within the Charophyceae?
A: The groups generally included within the Charophyceae are Coleochaetales, Charales, and some other related groups of green algae.
Q: How do some botanists classify Charophyceae?
A: Some botanists classify Charophyceae as a class under division Charophyta, while others suggest expanding the existing plant kingdom to include them.
