QUESTION 4
There are many similarities between the Charophyta and the land plants. While this implies an evolutionary relationship, it is not necessarily true that the land plants evolved from the modern-day Charophyta. What is a likely alternative explanation?
| a. |
Land plants are paraphyletic. |
|
| b. |
Both land plants and Charophyta have evolved from a common ancestor. |
|
| c. |
Land plants evolved from another group of algae. |
|
| d. |
Charophytes are the ancestors of land plants. |
|
| e. |
Land plants are the ancestors of Charophyta |
Homework Answers
Both land plants and Charophyta have evolved from a common ancestor.
Charophyta is an algae which is closely related to land plants by genetic similarity. One example is phragmoplast cell division which is same both the charophyta and land plants. So it is derived from a common ancestor.

WURDU MUHIWUILS) Figure 9.1 depicts the phylogenetic tree that includes all land plants and their closest protist relatives, a group of green algae called Charophytes. As seen in the phylogenetic tree, they all share a common ancestor. What would the Charophytes taxon be in this tree?
