Do Now Have your notebook and notecards ready under your desk in the basket. Have a piece of notebook paper ready and your desk clear for Quiz 3.

Quiz 3

Question 1 The nucleus is responsible for all of the following except storing DNA controlling the cell digesting bacteria housing chromosomes

Question 2 What is the function of lysosomes? Making DNA Making energy to fuel the cell Making lipids, carbohydrates, and proteins Breaking down nutrients and old organelles

Question 3 What is the difference between rough and smooth ER? Rough ER has surface ribosomes, while smooth ER does not. Smooth ER has surface ribosomes, while rough ER does not. Rough ER synthesizes lipids, while smooth ER does not. Smooth ER synthesizes proteins, while rough ER does not.

Question 4 Proteins are synthesized, packaged, and exported from a cell using all of the following organelles except Endoplasmic reticulum Golgi apparatus Mitochondria Ribosomes

Question 5 What is the function of mitochondria in the cell? Convert chemical energy in food into usable compounds Convert solar energy to chemical energy stored in food Regulate materials entering and exiting the cell Shape, support, and protect the cell

Question 6 You examine an unknown cell under a microscope and discover that the cell contains chloroplasts. From what type of organism does the cell likely come? Animal Bacteria Human Plant or algae

Question 7 Which of the following is a true statement about lipids in cell membranes? Hydrophilic lipid heads are attracted to water. Hydrophobic lipid fatty acid tails turn away from water. A bilayer forms when lipid heads turn toward water inside and outside the cell. All of the other answer choices

Question 8 Storing and transmitting genetic material is the function of which biomolecule? Lipids Carbohydrates Proteins Nucleic Acids

Question 9 Selectively permeable membranes are important in cell function. What makes a membrane selectively permeable? The ability to remove bacteria from the cell The ability to use energy to make proteins used in the cell The ability to modify, sort, and package proteins and lipids for storage or transport out of the cell The ability to allow needed materials to enter and wastes to exit as well as the ability to block unneeded materials from entering the cell

Question 10 Which of the following statements is not part of the Cell Theory? All living things are made up of cells Cells are the basic units of structure and function in living things All things are made up of cells New cells are produced from existing cells

Question 11 What is the general name for all of the specialized substructures in cells that help carry out the essential functions of life?

Question 12 The __________ is a network of fibrous proteins that helps the cell with maintaining shape, support, and movement. Cytoplasm Cell membrane Cytoskeleton Cell wall

Question 13 Which organelle acts like a “post office” by modifying, collecting, packaging, and distributing proteins and other materials? Vesicles Golgi apparatus Vacuole Endoplasmic Reticulum

Question 14 What do we call a structure in the nucleus of a cell consisting essentially of one long thread of DNA that is tightly coiled?

Question 15 What is cytoplasm?

Bonus Name an organelle that a plant cell has that animals cells do not.

Enzymes Review Mr. W Enzymes Video

Proteins Cellular processes are carried out by molecules. Proteins carry out most of the work of cells to perform the essential functions of life. One of the major functions of the cell is the production of proteins. The genetic information in DNA provides instructions for assembling protein molecules. In eukaryotic cells the nucleus, ribosomes, endoplasmic reticulum, vesicles, and the Golgi apparatus interact to produce, modify and transport proteins.

Plant Cells

Organelles Chloroplasts capture energy from sunlight and convert it into food that contains chemical energy in a process called photosynthesis Contain the green pigment chlorophyll

Organelles Cell wall: a strong supporting later around the cell membrane

Organelles Central Vacuole filled with liquid; the pressure of the CV in these cells increases their rigidity (making it possible for plants to support heavy structures such as leaves and flowers)
