Q&A Ch. 7
Biology Q&A Chapter 7
| Question | Answer |
|---|---|
| What is the cell theory? | The cell theory states: All living things are made up of cells; Cells are the basic units of structure and function in living things; New cells are produced from existing cells. |
| How do microscopes work? | Most microscopes use lenses to magnify the image of an object by focusing light or electrons. |
| How are prokaryotic and eukaryotic cells different? | Prokaryotic cells do not separate their genetic material within a nucleus. In eukaryotic cells, the nucleus separates the genetic material from the rest of the cell. |
| What is the role of the cell nucleus? | The nucleus contains proteins and other important molecules. |
| What are the functions of vacuoles, lysosomes, and the cytoskeleton? (Vacuoles) | Vacuoles store materials like water, salts, proteins, and carbohydrates. Lysosomes break down lipids, carbohydrates, and proteins into small molecules that can be used by the rest of the cell. They are also involved in breaking down organelles that have |
| What are the functions of vacuoles, lysosomes, and the cytoskeleton? (Lysosomes) | Lysosomes break down lipids, carbohydrates, and proteins into small molecules that can be used by the rest of the cell. They are also involved in breaking down organelles that have |
| What are the functions of vacuoles, lysosomes, and the cytoskeleton? (Cytoskeleton) | The Cytoskeleton helps the cell maintain its shape and is also involved in movement. |
| What organelles help make transport proteins? (Ribosomes) | Proteins are assembled on ribosomes. |
| What organelles help make transport proteins? (Rough ER) | Proteins made on the rough ER include those that will be released, or secreted, from the cell as well as many membrane proteins and proteins destined for lysosomes and other specialized locations within the cell. |
| What organelles help make transport proteins? (Golgi Apparatus) | The Golgi apparatus modifies, sorts, and packages proteins and other materials from the endoplasmic reticulum for storage in the cell or release outside the cell. |
| What are the functions of chloroplasts and mitochondria? (Chloroplasts) | Chloroplasts capture the energy from sunlight and convert it into food that contains chemical energy in a process called photosynthesis. |
| What are the functions of chloroplasts and mitochondria? (Mitochondria) | Mitochondria convert the chemical energy stored in food into compounds that are more convenient for the cell to use. |
| What is the function of the cell membrane? | The cell membrane regulates what enters and leaves the cell and also protects and supports the cell. |
| What is passive transport? | The movement of materials across the cell membrane without using cellular energy is called passive transport. |
| What is active transport? | The movement of materials against a concentration difference is known as active transport. Active transport requires energy. |
| How do individual cells maintain homeostasis? | To maintain homeostasis, unicellular organisms grow, respond to the environment, transform energy, and reproduce. |
| How do the cells of multicellular organisms work together to maintain homeostasis? | The cells of multicellular organisms become specialized for particular tasks and communicate with one another t maintain homeostasis. |
