What is this organism? (tear dropped shaped)
Giardia (Protist, diplomonad, parasitic)
What is Trypanosoma and what can it cause?
Parasites that infect the blood stream, but not blood cells directly. They can cause sleeping sickness.
What kind of protist is Malaria and describes its life cycle.
Plasmodium (Apicomplexan) Sporozoite > Merozoite > Gametocyte , Parasitic, infects blood cell
What are Paramecium (Ciliates)
Covered in cilia, have two nuclei
How do Amoeba (tubulinids) move
Move through Pseudopodia
Porifera (sponges + anatomy)
Sedentary, no body symmetry, lack tissues and organs,
What are the three body plans for Porifera
Ascon (simple), Sycon (intermediate), Leucon (complex)
Types of Sponge cells
Choanocytes - flagellated cells
Porocytes - form incurrent pores
Amoebocytes - scavenger cells, digestion, feed other cells
Pinacocytes - forms the outer layer
Dorsal, Ventral, Anterior, Posterior
Top, bottom, front, back
