1. THE ORGANELLE ORGAN SHOW

2. You will recall that cells are the third tier in the level of complexity; between molecules and ???????? tissues

3. Within most cells these are membrane bound, that is they have a membrane surrounding them and composed of membranes.

4. organelles

5. An envelope is a double membrane which has pores for flow of material.

6. Nuclear Envelope

7. A dark area of chromatin, it is involved in making ribosomes.

8. Nucleolus

9. Outside the nucleus, inside the cell membrane, the liquid portion (rich in proteins) that allows dissolved molecules to move within the cell.

10. Cytosol

11. Cytosol and organelles combined are called the ????

12. Cytoplasm

13. A spherical structure found either free floating in cytosol or attached to ER. These structures are the site of protein synthesis.

14. Ribosomes

15. A membrane system that may be continuous with the plasma membrane.

16. Endoplasmic Reticulum

17. Has many ribosomes on it and is the site of protein production (for secretion outside the cell).

18. RER

19. This has no ribosomes and serves to package the proteins produced in the RER. Proteins are collected within a bubble formed by the membrane

20. SER

21. This is a membrane system located close to the plasma membrane where proteins are modified and leave within a vesicle formed by membranes.

22. Golgi Apparatus

23. The main site of energy release inside the cell. Many enzymes are located within to help release energy from food molecules. The folded inner membranes assist in ATP production.

24. Mitochondria

25. These structures are found in cells which produce their own food (plants and autotrophs).

26. Plastids

27. Some examples of plastids are: chloroplasts - chlorophyll. chromoplasts - flowers and fruits. leucoplasts - starch formed from sugars here. What colour are they?

28. green; red, yellow and orange, clear

29. Cell’s storage containers. These are often large in plant cells and contain mostly water. They may also contain food, pigments and salt.

30. Vacuoles

31. These are structures that contain enzymes used to digest old cell structures. In animal cells these may aid in digesting food particles in a food vacuole.

32. Lysosomes

33. A system of microtubules and proteins that acts like a scaffolding structure within the cell. It can give a cell shape and allow for the passage of organelles.

34. Cytoskeleton

35. Common to animal cells, these structures are used during cellular reproduction, pulling the chromosomes to daughter cells during Anaphase and Telophase.

36. Centrioles

37. A barrier around the cell that allows only certain molecules in or out of the cell. It is composed of phospholipids with protein molecules embedded within.

38. plasma membrane

39. By definition, an organ system is an organ or group of organs that are comprised of specific tissue types. These tissues are usually coordinated so that they can perform specific functions for the whole animal. Specific tissue types can be created by cells that produce the same proteins and perform the same functions. (muscle cells have special proteins and nerve cells have special lipids, both cell types have specific and different functions)

40. Our bodies are composed of four general types of tissues, they are: Epithelial tissues, Connective tissues, Nerve tissue and Muscle tissue.

41. There are three general types of this tissue and they may be found in the gut, circulatory system and attached to the skeletal system.

42. Muscle tissues (smooth, cardiac and skeletal muscle).

43. These tissues are those that cover the surfaces and linings of organ systems (like the skin surface, stratified squamous epithelium).

44. Epithelial tissues

45. Can give structure to the body by serving to attach or support tissues (may be referred to as support tissues in some texts). These include bone and cartilage and loose tissue such as blood cells, fat cells, and loose fiberous tissue.

46. Connective tissue

47. Found through out the body and allow for communication between tissues of the body

48. Nerve tissues

59. Name these Systems’ Functions! Muscloskeletal or Skeleton and Muscles Skin Digestive system Respiratory system Excretory system

60. Name these Systems’ Functions! Circulatory system Immune system Nervous system Endocrine system Reproductive system
