This animal can reproduce both sexually and asexually. This animal is fertilized externally and develops externally.This animal is fertilized internally and develops externally.HW: IP: Unicellular Adaptations
2. What adaptations do unicellular (single-celled) organisms have to survive?
3. EyespotSpot that takes in lightFound in photosynthetic, single celled organisms (hint: they will be green!) Ex: euglena
4. Contractile Vacuole Pumps excess water out of the cell by quickly contracting Different than the regular vacuole https://www.youtube.com/watch?v=pahUt0RCKYc
5. FlagellaWhip-like tail used for locomotion Locomotion = movement
6. Cilia Small, fine hairs also used for locomotion or sweeping up foodhttps://www.youtube.com/watch?v=QGAm6hMysTA
7. PseudopodsGreek for “fake foot”Cytoplasm moves to engulf prey in a process called phagocytosisAlso aids in locomotion https://www.youtube.com/watch?v=pvOz4V699gk
8. Which organelle helps maintain homeostasis in protists?
9. Which organelle helps protists find light for photosynthesis?
10. Which organelle is found in amoebas and helps with movement?
11. Which organelle is used to sweep up food, and also for locomotion?
12. Which organelle is long and whip-like, and used for locomotion?
13. Malaria BasicsMalaria is a common disease in tropical areas, especially in Africa.
14. MalariaSymptoms:
15. Malaria BasicsMalaria is in the Protist kingdom and lives INSIDE of human red blood cells.+-What type of symbiotic relationship exists between malaria and humans?
16. Kingdoms of Life
17. MalariaMalaria is a parasite called Plasmodium
18. Malaria BasicsMalaria is transmitted (spread) by mosquitos. Vectors carry diseases from one organism to another. Because malaria is transmitted by female mosquitos, mosquitos are the vector.
19. THINK BoxWhat is malaria?Where is it most common?Define a vector:
20. Malaria Infection and TreatmentSymptoms: The way you feel because you have the disease.Malaria symptoms include fever, nausea and enlarged spleen.
21. Malaria Infection and TreatmentThe job of your spleen is to clean your blood. Your spleen is bigger, because it is working hard to get rid of the parasite in the red blood cells.
22. Malaria Infection and TreatmentPeople who have malaria can be cured by chloroquine which kills the parasite.
23. Sickle Cell and MalariaSickle cell is a recessive genetic disease. It causes a defect in hemoglobin, the protein in red blood cells that carries oxygen to the cells.
24. Sickle Cell Allele FrequencyWhere is the sickle cell allele most prevalent?
25. Malaria PrevalenceWhere is malaria most prevalent?
26. Malaria and Sickle CellSickle cell is most common in people from tropical areas. This is because of malaria! People who have the sickle cell allele are protected from malaria!7% of people of African descent carry the sickle cell allele. How is this an example of natural selection?
27. Genetics Word ProblemA woman with no sickle cell alleles marries a man who is a carrier for sickle cell. What is the likelihood that their children will have sickle cell anemia?
28. Genetics Word ProblemTwo carriers of the sickle cell allele have children. What is the likelihood that their children will have sickle cell anemia?
