Biodiversity Quiz Hints #3

From Lecture 5

1. Know that plants are multicellular photoautotrophic eukaryotes. Be able to describe what that means (i.e. what does each word mean).

2. Be able to explain what alternation of generations is. Explain gametophyte, sporophyte and how they relate to haploid and diploid.

3. What organisms exhibit alternation of generations?

4. Be able to describe what groups of plants have a dominant gametophyte generation and what group have a dominant sporophyte generation.

5. Know what characterizes each of the four stages of plant evolution. Look at figure 29.3 and know it well.
a. Know what characterizes the bryophytes. Be able to give examples of each (you may need to look in the book)
b. Know what characterizes the seedless vascular plants. Be able to give examples of each (you may need to look in the book)
c.What is the difference between a gymnosperm and an angiosperm? Be able to give examples of each (you may need to look in the book)

6. What organism do we think plants evolved from?

From Lecture 6

1. Know that an animal is a multicellular heterotrophic eukaryote. Know exactly what each word means and how that applies to all animals from sponges to you!

2. Know several characteristics of animals.

3. Know the four branch points in animal evolution. Be able to describe clearly each branch point.

4. Branch Point One: know what distinguishes parazoa from eumetazoa. What is an example of a parazoa?

5. Branch Point Two: know the difference between radial and bilateral symmetry.
Know the difference between diploblastic and triploblastic.

6. What phyla are radially symmetrical and diploblastic. Give a couple of common animals found in this phyla.

7. What is cephalization?

8. What is a coelom?

9. Branch Point Three: know the difference between acoelomates, pseudocoelomates, and coelomates. Be able to draw a cross section of each. Know the major animal phyla in each, and a couple of common animals in each phyla.

10. Branch Point Four: know the difference between protostomes and deuterostomes.
Be able to discuss the three different ways you can distinguish them embryologically. This is tricky and needs to be well understood. Look over the powerpoint slides carefully.
