Unit 4a
| Question | Answer |
|---|---|
| he flexible outer boundary of animal cells that allows only certain things to enter the cell and certain things to exit the cell is called | Cell membrane |
| are RNA and protein complexes that are found in all cells. These complexes help cells during protein translation by joining amino acids together to form polypeptides. | Ribosomes |
| The organelle(s) that makes ribosomes | The nucleolus |
| Ribosomes are made up of | RNA and protein |
| The organelle that is a long-whip like tail that moves the cell through its environment is called a | Flagellum |
| Which organelle has tunnel-like membranes, assembles components of the cell membrane and modifies proteins? | ER |
| The organelle(s) that is a transport system and synthesizes proteins are(is) | Rough ER |
| The site of photosynthesis | Chloroplast |
| Which statement best explains why nerve cell and red blood cells have structural differences? | They have different functions |
| An internal network of protein fibers that helps keep the shape of the cell and assists the cell in movement is called the | cytoskeleton |
| The cell membrane is mostly made up of | A lipid called phospholipids |
| According to the cell theory, all living things are made up of | Cells |
| Membrane organelles known as _______ contain enzymes specialized to break down ingested materials, secretions, and wastes. | Lysosomes |
| Which organelle modifies protein and lipids from the ER, repackages them, and transports them to different parts of the cell with vesicles? | Golgi Apparatus |
| Centrioles produce | Spindle Fibers |
| The brain or control center of the cell is called the | Nucleus |
| The organelles that are short hair-like structures that move the cell through its environment is called a | Cilia |
| According to the cell theory, the basic unit of structure of living things are | Cells |
| The organelles that produce spindle fibers are | Centriole |
| The site of cellular respiration | Mitochondria |
| A rigid outer boundary in plant cells, algae, fungi, and bacteria is called a | Cell wall |
| organelles is not found in animal cells but in plant cells | a large vacuole |
| A scientist observes a single-celled organism with several long, whip-like tails. Which function do the whip-like tails most likely perform for the organism? | Movement through an environment |
| According to the cell theory, new cells are made from | Cells |
| The smooth ER synthesizes | lipids |
| The cell wall is made up of | A carbohydrate called cellulose |
| The Golgi apparatus is broken down during mitosis and then reformed. Which function would a cell be unable to perform during the time that its Golgi apparatus is broken down? | processing and packaging proteins for cellular export |
| Eukaryotic cells contain organelles that harvest energy from organic compounds to make ATP. ATP is the main form of energy used by cells. Which cell organelles are responsible for making most of the cell's ATP? | mitochondria |
| Prokaryotic and eukaryotic cells have many differences, but they also share some common features. Which of the following may be found in either type of cell? | Cell walls |
| The rough ER synthesizes | Proteins |
| The organelle(s) that assembles amino acids to make proteins are (is) | Ribosomes |
| Within eukaryotic cells, there is an intricate network of _______ with unique functions. | Organelles |
| Which microscope can look at living things? | Light microscope |
| Which of the following organelles contains most of the cell's DNA? | Nucleus |
| Which of the following organelles plays a role in the disposal of cellular waste and is responsible for processing, sorting, and modifying proteins? | Golgi Apparatus |
| The cell membrane is also made up of | Protein |
| Chromatin is made up of | DNA and protein |
| The green pigment that captures sunlight is called | Chlorophyll |
| Organelles filled with enzymes that digest food and worn out cell parts are | Lysosomes |
| The life forms exhibiting the simplest cellular structure are _______. | Prokaryotes |
| The organelle that has pores and allows things to enter and leave the nucleus is called the | Nuclear envelope |
| Pro and Eu both | have cell membranes, DNA, Ribosomes, and cytoplasm |
| Plant cell (3 C's) | Chloroplasts, Cell wall, central vacuole |
| Animal cells have | lysosomes, small vacuoles, centrioles, cilia, flagella |
