Identify this cell. |
Sickle cell anemia in red blood cells |
|
Describe the relationship between sickle cell anemia and malaria |
Sick cell imparts some protection from malaria |
|
Identify the domain and next lowest taxon of these organisms. |
Domain bacteria; Cyanobacteria |
|
Identify the heterocysts on this Anabena specimen. What is the function of heterocysts?
|
The round cells separated by chains of photosynthetic cells are the heterocysts. Function: nitrogen fixation. |
|
Identify the akinete cells on these samples of Anabaena. Why are akinetes important? |
The large, dense, spore-like cells are akinetes. They are important because they help the cell survive adverse conditions |
|
To what Domain does this organism belong? |
Bacteria (cyanobacteria) |
|
What are the large dark structures called and what are their functions? |
Akinetes; survive adverse conditions |
|
Name three environmental functions of these organisms. |
Produce oxygen, absorb excess carbon dioxide, primary producers for marine ecosystems |
|
What is the name of the clear, round cells in this organism and what is their function? |
heterocysts; nitrogen fixation |
|
What phylum is this?To what Supergroup does this organism belong? How does it move? |
Euglena; Excavata; flagella |
|
What organism is this and how does this organism obtain food? |
Euglena; photosynthesis |
|
What organism is this? Identify the major organelles. How does it obtain food? |
Euglena; refer to lab manual page 59; photosynthesis |
|
Identify the organism. What disease does it cause? |
Tyrpanosome; African sleeping sickness (pg 60) |
|
What are these organisms? What structures differentiate these Alveolates from other members of the taxon? |
Dinoflagellates; armored plates and two perpendicular flagella (pg 61) |
|
What organism is indicated by the "ring" structure and what medical condition is indicated? |
Plasmodium Vivax; malaria |
|
To what supergroup does this organism belong? What is the organism? |
SAR Clade; Paramecium (pg 62,63) |
|
Identify this organism and how does it move? |
Paramecium; cilia (pg 62,63)
|
|
Identify the organism. To what domain and supergroup does it belong? |
Achlya; Eukarya; SAR Clade (pg 64) |
|
Identify the organism and the oogonium and zoosprangium on this slide. |
Achlya; oogonium upper, zoosporangium lower (pg 64) |
|
What is this organism? Why were organisms like this called "water molds" if they do not belong to the Fungi? |
Saprolegnia; because they have filaments much like the hyphae/mycelia of the true fungi (pg64) |
|
What is this organism? What are the hairlike filaments of this organism called? |
Saprolegnia; hyphae/mycelia (pg 64) |
|
What organism does this structure belong to? What is the structure? What is produced within the structure? |
Saprolegnia; oogonium; egg nuclei (pg 64) |
|
What organism does this structure belong to? What is the structure? |
Saprolegnia; zoosporangium (pg 64) |
|
What is this organism?How do the psuedopodia of these organisms differ from that of the amoebas? |
Foram; filamentous as opposed to lobed in amoebas (pg 65) |
|
What is this organism? How does the "shell" of this organism differ from that of the radiolarians? |
Foram; made of calcium in instead of silica (pg 65 |
|
What type of organism is this? What characteristic places these organisms in the Rhizaria? |
Radiolaria; filamentous pseudopodia (pg66) |
|
