What am I? Cell Structure and Function Review

1. What am I?Cell Structure and Function Review

2. What am I? • I modify proteins & lipids. • I am a stack of flattened membranes. • I send packages (vesicles) through (or out of) the cell. Answer I am the Golgi apparatus.

3. What am I? • I am separately enclosed in my own membrane. • Some examples of me are Golgi apparatus, lysosomes, vacuoles, mitochondria, chloroplasts. Answer I am a cell organelle.

4. What am I? • I make up plants, animals, fungi, and protists. • I have many different types of membrane-boundorganelles. • I have a nucleus which protects my chromosomes. Answer I am a eukaryotic cell.

5. What am I? • Folds of my membranes are used to package & modify proteins made by ribosomes. They also make lipids • I have 2 types. • "Rough" - which is usually near nucleus and covered with ribosomes giving it its "rough" appearance. • "Smooth" - which is usually away from the nucleus Answer I am endoplasmic reticulum.

6. What am I? • I am very small. • I was the original living inhabitant of Earth. • I do not have a nucleus. • I do not have membrane-bound organelles. • Examples of me include eubacteria and archaebacteria • I have a single strand of circular "naked" DNA Answer I am a Prokaryotic cell.

7. What am I? • I contain DNA packaged in structures called chromosomes. • I control most cell processes. • I contain a nucleolus. • I am surrounded by a nuclear envelope. Answer I am the Nucleus.

8. What level of organization am I? • I am made up of cells that are similar in structure and function. • The cells that make me up work together to perform a specific activity. • Humans have 4 basic types: connective, epithelial, muscle, and nerve. Answer I am tissue.

9. What am I? • I am the living material between the nucleus and the cell membrane • I contain other structures. Answer I am cytoplasm.

10. What environment am I? Answer Hypertonic

11. What Am I? • I provide support and protection for plants, fungi, and other cells. • I am made of cellulose or chitin. Answer I am the cell wall.

12. What level of organization am I? • I can serve a specific function within the organism. • I can be part of a living thing. • I can be a complete living thing. • I am the basic unit of structure and function in living things. Answer I am a cell.

13. What am I? Answer I am a eukaryotic cell.

14. What am I? • I am NOT membrane-bound. • I am found in prokaryotes. • I am granular in appearance. • Often I am found on "rough" endoplasmic reticulum. • I manufacture proteins. • Answer • I am Ribosomes.

15. What am I? • I digest food particles. • I destroy worn-out organelles. • I destroy worn-out cells. • I contain a powerful digestive enzyme. Answer I am a lysosome.

16. What am I? Answer Diffusion

17. What am I? • I am sometimes called the "powerhouse of the cell“. • I generate chemical energy by breaking down glucose. • I am the site of cellular respiration. • Answer • I am the mitochondria.

18. What am I? • I am the site of photosynthesis. • I contain chlorophyll- a green pigment • I am found in plant cells and some protists. Answer I am a chloroplast.

19. What level of organization am I? • I represent the entire living thing. • I can carry out all basic life processes such as take in materials, release energy from food, release wastes, grow, respond to the environment, and reproduce. • I am usually made up of organ systems. • I can made up of only one cell such as bacteria or protist. Answer I am an organism.

20. What am I? Answer I am a Prokaryotic cell

21. What am I? • Diffusion and osmosis are examples of me. • I am the movement of molecules from areas of greater concentration to areas of lesser concentration that occur WITHOUT the use of energy. Answer PassiveTransport

22. What am I? • I occur in some prokaryotes, protists & animals. Do not occur with fungi and plants • I serve as construction/ organization points for cellular microtubules • I organize and transfer chromosomes and other organelles during meiosis & mitosis I am tube-like structures that are usually at right angles to each other. Answer I am the centrioles.

23. What am I? • I occur only in water. • I am the diffusion of water through a selectively permeable membrane. Answer I am osmosis.

24. What level of organization am I? • I am made of groups of two or more organs that work together to perform a specific function for the organism. • The Human body has 11 of me - circulatory, digestive, endocrine, excretory (urinary), immune (lymphatic), integumentary, muscular, nervous, reproductive, respiratory, and skeletal. Answer I am an organ system.

25. What environment am I? Answer Isotonic Cell

26. What am I? • I am a type of transport. • I am movement of molecules from a less crowded to a more crowded area. • I need energy. Answer I am active transport.

27. What level of organization am I? • I can serve a specific function within the organism • I am the basic unit of structure and function in living things. • I can be part of a living thing. • I can be a complete living thing. Answer I am a cell.

28. What level of organization am I? • I am made up of tissues that work together to perform a specific activity. • I could be a heart, a brain, skin, or lungs. Answer I am an organ.

29. What am I? • Plant cells have a large one of me. • I provide turgor pressure to maintain plant cell structure. • I can store water, lipid, waste, and food. Answer I am a vacuole

30. What environment am I? Answer Hypotonic

31. What am I? • Cells are the basic units of life. • All living things are made of cells. • All cells are produced by existing cells. Answer I am the Cell Theory.
