Malaria and Algae

NPR had a story this morning about an organelle found in the malaria parasite that is now believed to have come from algae. Bio 120 students are learning about malaria in lab this week along with algae, so this story comes along at just the right time. Bio 200 students, we will be discussing malaria on Friday, so take a listen to the story here

Tentacles at the Aquarium of the Pacific

All of these photographs are of animals from Phylum Cnidaria. They all can capture prey using stinging cells that paralyze the prey. However most also are algae farmers. Algae live in the animal's cells and to photosynthesis to make carbohydrates. Some coral animals get 90% of their food this way and die without their algae partners.

1. What are two important factors in determining what type of Biome one will find in a given area?

2. What causes the seasons here in North America?

3. What are three strategies plants have developed to survive in the cold dry,and sometimes dark conditions of the Tundra?

4. What kind of adaptations have animals developed to survive in:
A. The tundra
B. The deserts
C. Coniferous forests

5. What is a rain shadow, and how does it account for different plant communities occurring at the same latitude, but on opposites sides of a mountain range?

6. In what biomes does fire play an important role, and what is this role?

7. To what kind of environmental stresses are the plants and animals in the chaparral adapted?

Population Ecology and Interactions

1. Define resource partitioning and give an example of it.

2. How is a parasite different from a parasitoid?

3. How is a parasite different from a predator?

4. How are density dependent limiting factors different from density independent limiting factors? Give examples of each.

5. Coevolution happens also between parasites and their hosts. Why is this not surprising?

6. Define and give examples of the following: Mutualism, Commensalism, social parasite.

7. What are common strategies predators use to capture prey, and common defenses found in prey?

8. Draw a food web that could occur in your backyard or here at Cerritos. Include all the trophic levels we discussed in class.

9. Why are there fewer members of the upper trophic levels as compared with primary consumers or the producers?

10. What is carrying capacity?


1. How is a genotype different from a phenotype?
2. What name is given to each of the following genotypes: TT Tt tt
3. Which of Mendel's laws discusses the separation of alleles in meiosis?
4. Which of his laws would describe the behavior of human chromosome 2 and 13 during meiosis?
5. In peas, tall is dominant over short. If two plants tall heterozygous plants were crossed, what proportion of the offspring would you expect to be short?
6. In one breed of chickens feather color is black, blue-gray, or white. How is feather color inherited and why do you think so?
7. If mom has 0 blood, and dad has AB blood, what proportion of the children will have B blood?
