cells

• What are cells often referred to as?

  Cells are often called the "building blocks of life".
• What is the smallest unit of life that can function independently?

  A cell is the smallest unit of life that can function independently.
• What do all living things consist of?

  All living things are made up of one or more cells.
• What does a cell contain that is crucial for its function?

  Cells contain the organism's genetic material (DNA).
• How do cells reproduce?

  Cells can reproduce through cell division.
• How many cells does a human body contain?

  A human body contains trillions of cells.
• What is an example of a single-celled organism?

  Bacteria are an example of a single-celled organism.
• What is the main function of mitochondria?

  The main function of mitochondria is to produce energy for the cell.
• What process do mitochondria use to produce energy?

  Mitochondria produce energy through a process called cellular respiration.
• What is ATP?


  ATP (adenosine triphosphate) is the energy currency of the cell.
• What is the main function of vacuoles?

  The main functions of vacuoles include storage, maintaining cell shape, regulating cell size, and digestion.
• How do vacuoles help maintain cell shape in plant cells?

  In plant cells, the large central vacuole helps maintain the cell's structure and rigidity.
• What do vacuoles regulate in a cell?

  Vacuoles regulate the amount of water inside the cell, adjusting its size.
• What do lysosomes contain?

  Lysosomes contain enzymes that break down various molecules.
• What is the basic structure of a cell composed of?

  The basic structure of a cell includes the cell membrane, cytoplasm, nucleus, and organelles.
• What is the function of the cell membrane?

  The cell membrane is a thin, flexible barrier that surrounds the cell, controlling what enters and exits.
• What is cytoplasm?


  Cytoplasm is a jelly-like fluid inside the cell where organelles float.
• What does the nucleus contain?

  The nucleus contains DNA and is the cell's control center.
• What is the role of organelles in a cell?

  Organelles are specialized structures within the cell that perform specific functions.
• What is the function of ribosomes?


  Ribosomes synthesize proteins.
• What is the cytoskeleton's function?

  The cytoskeleton provides structure and facilitates movement within the cell.
• What is the function of the Golgi apparatus?

  The Golgi apparatus modifies, packages, and distributes cellular products.
• What is the difference between plant and animal cells regarding cell walls?

  Plant cells have a cell wall, while animal cells do not.
• What organelles are present in plant cells but not in animal cells?

  Plant cells have chloroplasts and a large central vacuole, which are not found in animal cells.
• How do plant and animal cells differ in shape?

  Plant cells are usually rectangular, while animal cells are often round or irregular.
• What is cell specialization?

  Cell specialization is the process by which cells become specialized to perform specific functions.
• What are stem cells?


  Stem cells are basic cells that can differentiate into various cell types.
• Why is cell specialization important in multicellular organisms?

  Cell specialization allows for division of labor within an organism, enabling different cells to perform specific functions efficiently.
• What is an example of a specialized cell?

  A nerve cell is an example of a specialized cell.
• How do muscle cells differ from nerve cells?

  Muscle cells contain protein fibers for contraction, while nerve cells are long and branched for transmitting signals.
• What is the shape of red blood cells and their function?

  Red blood cells are disc-shaped and packed with hemoglobin for oxygen transport.
• How does cell specialization contribute to the efficiency of multicellular organisms?

  Cell specialization allows different cells to work together efficiently in complex organisms.
