This introductory document explores the phylogenetic history, life cycles, and reproductive nature of plants, highlighting their evolution from green algae. It discusses the significance of key traits shared between land plants and their algal ancestors, the main groups of plants, and the challenges faced by both plants and animals upon colonizing land. Key adaptations that have contributed to the success of plants on land are identified, along with the importance of lignin and vascular tissue. Furthermore, the group that includes mosses, hornworts, and liverworts is examined along with their reproductive structures.

Introductory Questions #1 Plants have thought to evolved from a group of green algae called ? Why do evolutionary Biologists think that this algal species is the common ancestor of land plants? (Give four key traits they have in common-pg. 574) Name the four main groups of plants. Name the four main challenges faced by plants and animals as they emerged on land. Name three key adaptations in plants allowing them to be successful on land. What is the significance of lignin and the vascular tissue found in land plants? Moss, hornworts, and liverworts are all part of which group of plants? Looking at the life cycle of the moss, what is the name of the male and female reproductive structures?
