a. Are produced inside the mosquito body
b. Are produced both inside the mosquito body and inside the human red cells
c. Are produced inside the human red cells
d. Are produced inside the liver cells
2) Which of the following is correct on Giardia?
a. It does not have gametes that are easily identifies under microscopes
b. It produces proteins that surround each individual forming cysts
c. It has relictual mitochondria
d. It has genes for meiosis
e. All other option are correct
3) Which of the following organisms do not have a cell wall?
a. Giardia
b. Trypanosoma
c. Amoeba
d. They all have cell walls
e. None of them have cell walls
4) Green algae are:
a. Monophyletic
b. Paraphyletic
c. Polyphyletic
d. We are not certain as their phylogenetic studies have low resolution
5) Once plants colonized land, they needed to adapt to UV radiation. It is believed that to
adapt to their haplodiplontic life cycle, they:
a. Had to shift to be predominantly diploid
b. Had to shift to be predominantly haploid
c. Did not need to make any change in their life cycle as the ozone layer protects life
from ultraviolet radiations
d. Develop vascular tissue
e. Developed a cuticle
6) In liverwort the sporophyte:
a. long lived and large independent individual called seta with many cells, including
rhizoids
b. short lived and small tissue called seta with relatively few cells that undergo
meiosis shortly after fertilization. It is surrounded by haploid tissue of the
gametophyte.
, c. Is an embryo called seta with a single cell that undergoes meiosis right after
fertilization. It is surrounded by haploid tissue of the gametophyte

12) Cell roots:
a. Use energy to activate enzymes that move water inside the root
b. Use energy to activate enzymes that move ions inside the root
c. Need to have ions inside the cytoplasm to move water inside the root
d. A, B, and C are correct
