b. slime molds.
c. red algae.
d. green algae.
e. charophytes.

Students have asked these similar questions
Which of the following is not true about green algae?
A. They are a morphologically diverse group
B. They are the closest living relatives of land plants
C. The group includes the most recent common ancestor and all the descendants
D. They share several morphological similarities with land plants
Epiphytes are(A) fungi that attack plants.(B) fungi that form mutualistic associations with roots.(C) nonphotosynthetic parasitic plants.(D) plants that grow on other plants.
Why is the classification of protists based on DNA sequences useful? *
a. Because only protists have DNA
b. Because it has confirmed the traditional categories for protists
c. Because it has revealed evolutionary relationships, even among organisms that look diffferent
d. All of the above are correct
This is a required question
(2) Why is a species with small population more likely than one with a large population to undergo an extinction? *
a. Because small population are exposed to greater environmental changes
b. Because genetic diversity is likely to be lower in a small population
c. Because the mutation rate is too low
d. Because they take too long to produce an offspring.

- Lichens are said to be composite organisms made up of two very different types of organisms: usually a fungus and an alga (or in a few lichens, a fungus and a Cyanobacterium). (Alga is the singular of algae.) How do these two types of organisms work together to become a functional composite organism? That is, what does each organism provides to the relationship to make it successful?
