What is the basic structural and functional unit of all living organisms? | The cell |
Which part of the cell regulates the passage of substances in and out and separates the cell's interior from its external environment? | The cell membrane (plasma membrane) |
What is the control center of the cell that contains genetic information and directs cellular activities? | The nucleus |
Which organelle is often called the "powerhouse of the cell" and is responsible for producing ATP? | The mitochondria |
In which organelle are proteins synthesized and modified before being transported to their final destinations? | The endoplasmic reticulum (ER) |
Which organelle packages and sorts proteins and lipids for transport within or outside the cell? | The Golgi apparatus |
Which cellular structure is responsible for digesting waste materials and cellular debris? | The lysosome |
What is the function of the cytoplasm in a cell? | It serves as the gel-like substance that suspends organelles and other cellular components. |
What is the cell membrane primarily composed of? | Lipid bilayer |
What are the tiny hair-like structures on the cell surface that assist in moving materials along the cell's surface? | Cilia |
What are small membrane-bound sacs that transport and store substances within the cell? | Vesicles |
What is the function of the ribosomes? | The ribosomes are responsible for protein synthesis. They translate the mRNA into proteins, which are the building blocks of life. |
What is the role of cells in the body? | Cells play an essential role in the body. They are responsible for all of the body's functions, including growth, repair, and reproduction. |
What is the role of microvilli in a cell? | Microvilli increase the surface area of the cell, particularly in absorptive cells. |
Which cell structure is involved in cell division and is composed of protein fibers? | The centrioles |
What is the name of the structure within a cell that is responsible for the breakdown of fatty acids and amino acids? | The peroxisome |
