Name: __________________ Biology: Unit 4 CELLS- Structure and Function This test will cover: Chapter 7 in textbook. The following questions provide an idea of the subject matter that will be covered and provide a beginning to your studying. Just because something is not on this sheet does not mean that it will not be on the test. Review all your notes, lab papers, vocabulary list and quizzes to prepare. 1. What type of cell is shown below? ___________________ List 3 things present in this cell that helps you determine the type of cell it is: 1._______________________ 2._______________________ 3._______________________ 2. Clearly and neatly draw an animal cell and add the following organelles: Nucleus, Nucleolus, Smooth ER, Rough ER, Golgi Body, Mitochondria, Ribosomes, Cell membrane, Centrioles (always a pair!), Lysosomes, Cytoplasm. Label each part! 3. What organelle is only found in animal cells? ________________ What is its function? __________________________________________ 4. What cell parts are found in ALL cells (both eukaryotic and prokaryotic!) 1. _________________ 2. _________________ 3. _________________ 4. DNA 5. The three statements of cell theory: 1. All living things are made up of one or more ____________. 2. The cell is the smallest unit of ____________. 3. Cells come from existing ____________. Name the three scientists that are responsible for providing some of the first evidence for those ideas. _____________________, ____________________ & ___________________ 6. What organelle or cell part is described? Oval, produces ATP (energy), site of cellular respiration - __________________________ Oval, green, makes glucose, site of photosynthesis- _______________________________ Large, round, contains DNA, controls the cell, found in all eukaryotic cells- _____________ Smallest organelles, not membrane-bound, site of protein assembly from amino acids- _____ Largest organelle in plant cell, stores water and other substances- _________________ Network of tunnels that synthesize substances- _______________________ Found inside the nucleus, makes RNA (ribosomes are made of RNA) - _________________ Round, contains enzymes to break down substances within the cell- _________________ Semi-fluid substance containing chemicals for reactions taking place within the cell, the organelles “float” in this - ________________________ Boundary of the cell, regulates what enters and leaves the cell, made of phospholipids and proteins- ___________________ Rigid, outermost part of plant cell, contains cellulose- ____________________ Barrel shaped, always found in a pair, help with cell division- _____________________ 7. Diffusion is the movement of substances from an area of __________ concentration to an area of _________ _________________. Net flow of the substance will stop once an ___________________ is reached. A concentration ______________ is needed for diffusion to occur. 8. Osmosis is the movement of ________ from an area of __________ concentration to an area of _________ _________________. 9. When comparing 2 solutions the one with more solute is called ______________. The one with less solute is ______________. If the concentrations of solutes are equal the two solutions are ___________________. 10. In each diagram below determine the direction of net flow: Assume the membrane is semi-permeable (selectively permeable) and will allow water, glucose and iodine to pass through but not starch or salt. Semi permeable 10% iodine 10% NaCl 2% iodine Pure water A B 20% glucose 10% glucose C 2% starch 10% starch D 5% glucose 10% glucose e E Which diagrams are showing the diffusion of a solute? _______________ Which diagrams are showing osmosis? _____________________ 11. When water moves out of the plant cell, the ____________ _______________ pulls away from the cell wall as the interior of the cell shrinks. This is called _____________________. 12. When the plant cell is full of fluid/water it pushes out and puts pressure on the cell wall. This is called _________ pressure. This gives plants support. If there is no turgor pressure, we say the plant has “wilted”. 13. Why don’t animal cells have turgor pressure? ___________________ What happens to animal cells that take in too much water? ____________________ 14. Label the parts of the prokaryotic cell: 15. Label the parts of the cell membrane: 16. Proteins in the cell membrane can function as receptors or __________ to move substances from one side of the membrane to the other. This is known as _______________________ diffusion which is passive (does not require energy). If energy (ATP) is required to move a substance it is known as _____________ transport. 17. Simple diffusion and facilitated diffusion require NO energy and therefore are considered _______________________. Active transport does not require a concentration gradient; molecules can move against a gradient and therefore _______________ must be used. 18. Why do phospholipids orient themselves into a bilayer?___________________________ What part of the phospholipid is hydrophobic? ______________________ 19. Cells can move in (or out) molecules through the cell membrane. However, larger particles may require a different way of entering (or leaving) the cell. Define: Endocytosis- __________________________________________________________ Exocytosis- ___________________________________________________________ 20. Cell membranes are described by the ______________ mosaic model. This means the cell membrane is made up of many different pieces and that they can move around and change places! 21. Cells are very small because a _________________ surface area allows things to move in and out of the cell quickly. A high _____________ _____________ to volume (space inside the cell) ratio is seen in cells. BE SURE TO THOROUGHLY COMPLETE THIS, STUDY IT and KNOW THIS INFORMATION FOR THE TEST. Turn this packet in on test day. It will not be accepted late. Vocabulary list is posted on my webpage.
