2. IV. Support & Locomotion A. Cytoskeleton = network of fibrous elements that as a scaffold for support for organelles

3. IV. Support & Locomotion B. Cilia = hairlike projections from the plasma membrane.

4. IV. Support & Locomotion C. Flagella = longer projections that move w/a whip-like motion. ex: sperm cells

5. V. Cellular Organization A. Unicellular = single-celled organisms [bacteria] B. Multicellular = organisms made up of many cells 1. cells are differentiated to perform specific functions

6. C. Tissue = a group of cells that function together to perform an activity [muscle, nerve, etc.] V. Cellular Organization

7. D. Organs = groups of tissues that function together [heart, liver, etc] V. Cellular Organization

8. E. Organ system = group of organs that carries out a major life function [nervous system] V. Cellular Organization

9. For Q’s 16-21, use the key to match a. cytoskeleton b. tissue c. organ d. organ system e. flagella f. cilia the term with the proper phrase. 16. Long projections that move with a whip-like motion that help certain cells move

10. 17. Group of tissues that cooperate to carry out specific functions in an organism [a leaf for example] For Q’s 16-21, use the key to match a. cytoskeleton b. tissue c. organ d. organ system e. flagella f. cilia the term with the proper phrase.

11. 18. Network of fibrous elements that as a scaffold for support for organelles For Q’s 16-21, use the key to match a. cytoskeleton b. tissue c. organ d. organ system e. flagella f. cilia the term with the proper phrase.

12. 19. Group of organs that carry out a major life function in organisms [lymphatic for example] For Q’s 16-21, use the key to match a. cytoskeleton b. tissue c. organ d. organ system e. flagella f. cilia the term with the proper phrase.

13. 20. Hairlike projections from the plasma membrane that aid in locomotion For Q’s 16-21, use the key to match a. cytoskeleton b. tissue c. organ d. organ system e. flagella f. cilia the term with the proper phrase.

14. 21. A group of cells that function together to perform an activity [epithelium for example] For Q’s 16-21, use the key to match a. cytoskeleton b. tissue c. organ d. organ system e. flagella f. cilia the term with the proper phrase.

15. 22. Most multicellular organisms are ___________________. a. prokaryotes b. eukaryotes

16. [Bonus] The term “cell” was first coined by the English scientist ____________________. a. Anton van Leeuwenhoek d. Robert Hooke b. Matthias Schleiden c. Johannus Vermicelli
