Functions of cell components

• How does the cytoplasm facilitate essential cell processes?

  By enabling chemical reactions to occur
• What can leave the cell through the membrane?

  Waste products are allowed to leave
• What are mitochondria known as in cells?

  Powerhouses
• What do thylakoids contain that is essential for photosynthesis?

  Chlorophyll
• How does the cell membrane function like the walls of a house?

  It separates the interior from the outside world
• What are the main functions of the plant cell wall?

  • Provide structural support and rigidity to the plant cell
  • Allow selective permeability for transport of materials in and out of the cell
• What are the main functions of the cytoplasm?

  • Gel-like substance filling the cell's interior
  • Supports and suspends organelles
  • Facilitates essential chemical reactions
• What type of cells have a cell wall?

  Plant cells
• What type of genetic material is contained in the nucleus?

  DNA
• How does the cell wall help maintain cell shape in plants?

  By providing a rigid structure
• What is the function of the nucleus in a cell?

  It is the cell's control center
• What is the primary function of the cell membrane?

  To keep everything inside the cell safe
• What types of substances can enter the cell through the membrane?

  Nutrients can enter the cell
• What does the cytoplasm support within the cell?

  Organelles
• How does the large vacuole in plant cells contribute to cell rigidity?

  By pushing against the cell wall
• What process do mitochondria use to produce ATP?

  Cellular respiration
• What is a vacuole?

  A membrane-bound storage compartment
• If a cell has a high demand for energy, what would you expect to see in the number and size of its mitochondria?

  An increased number and size of mitochondria
• Why are mitochondria sometimes referred to as the "powerhouses" of the cell?

  Because they produce the majority of a cell's ATP, the energy currency of the cell
• How does the gel-like nature of the cytoplasm benefit the cell?

  It allows organelles to be suspended and move
• What is the primary component of the cell wall in plant cells?

  Cellulose fibers
• What is the primary role of the cytoplasm in a cell?

  Facilitates chemical reactions for cell function
• What is the primary function of mitochondria?

  Producing energy in the form of ATP
• What is the cytoplasm?

  Gel-like substance inside a cell
• What is the primary function of the plant cell wall?

  To provide structural support and protection for the plant cell
• What are the key functions of the cell wall in plant cells?

  • Protection against cell bursting
  • Maintains cell shape
  • Supports plant growth
  • Allows free movement of water/solutes
• If a plant cell has a thick, rigid cell wall, how would this affect the cell's ability to change shape or size?

  The cell would have limited ability to change shape or size
• What are the key differences between the plant cell wall and the animal cell membrane?


  • Composition: Plant cell wall is made of cellulose, animal cell membrane is made of phospholipids
  • Function: Plant cell wall provides structural support, animal cell membrane controls permeability
  • Location: Plant cell wall is outside the cell membrane, animal cell membrane surrounds the entire cell
  • Rigidity: Plant cell wall is thick and rigid, animal cell membrane is thin and flexible
• How does the structure of the plant cell wall differ from the animal cell membrane?

  • Plant cell wall is thick, rigid and made of cellulose
  • Animal cell membrane is thin, flexible and made of phospholipids
  • Plant cell wall provides structural support, animal cell membrane controls permeability
  • Plant cell wall is outside the cell membrane, animal cell membrane surrounds the entire cell
• What is the main function of the cell wall?

  Provides protection and support to plant cells
• What is the function of chloroplasts in plant cells?

  Photosynthesis occurs in chloroplasts
• What is the name of the organelle labeled as "Nucleus" in the image?

  Nucleus
• Why is the cell wall important for plant growth?

  It supports the plant as it grows
• What are the main functions of the cell membrane?

  • Acts as a border, keeping inside and outside separate
  • Selectively controls what enters and exits
• How does the cell wall compare to the cell membrane in plant cells?

  It is a tougher version of the cell membrane
• What is the function of water storage vacuoles?

  Maintain cell shape and turgor
• What is the main function of mitochondria in a cell?

  To produce ATP through cellular respiration
• What does the cell wall allow to move freely?

  Water and solutes
• What does it mean that the cell membrane is selective?

  It controls what enters and exits the cell
• What do protein storage vacuoles do?

  Store proteins and nutrients
