plant and animal cells

• What are the two main types of cells mentioned?

  Plant and animal cells
• What features are common to both plant and animal cells?

  • Cytoplasm for chemical reactions
  • Cell membrane controlling entry and exit
  • Nucleus containing DNA for cell activities
  • Mitochondria for aerobic respiration and energy supply
• What is the function of the cytoplasm in cells?

  It facilitates chemical reactions for life
• What role does the cell membrane play?

  It controls what enters and leaves the cell
• What is contained within the nucleus?

  DNA that controls cell activities
• What is the singular form of mitochondria?

  Mitochondrion
• What is the primary function of mitochondria?

  They carry out aerobic respiration for energy
• How do plant cells differ from animal cells?

  Plant cells have:

  • Cell wall made of cellulose
  • Large, permanent central vacuole
  • Chloroplasts for photosynthesis

  Animal cells lack these features.
• What is a cell wall made of?

  Cellulose
• What is the function of a central vacuole in plant cells?

  It stores cell sap and maintains turgor pressure
• What do chloroplasts absorb for photosynthesis?

  Light
• Are chloroplasts found in animal cells?

  No, they are not found in animal cells
• What does Figure 1.1 illustrate?

  The structure of animal and plant cells
• What are the key components found in both plant and animal cells?

  • Cell membrane
  • Cytoplasm
  • Nucleus
  • Mitochondria
• What is the primary role of the cell membrane in both plant and animal cells?

  To control entry and exit of substances
• What is the function of the cytoplasm in both plant and animal cells?

  It is where chemical reactions occur
• What is the function of the nucleus in both plant and animal cells?

  It contains DNA for cell activities
• What is the role of mitochondria in both plant and animal cells?

  They provide energy through respiration
• What is the role of the nucleus in both plant and animal cells?

  It controls the cell's activities
• What are the unique features of plant cells not found in animal cells?

  • Cell wall made of cellulose
  • Large central vacuole
  • Chloroplasts for photosynthesis
• What is the primary function of chloroplasts?

  To absorb light for photosynthesis
• What is the significance of the central vacuole in plant cells?

  It maintains turgor pressure and stores substances
• What is the structure of the cell wall in plant cells?

  It is made of cellulose
• How do chloroplasts contribute to plant cells?

  They enable photosynthesis by absorbing light
• What is the main difference between plant and animal cells regarding vacuoles?

  Plant cells have large, permanent vacuoles
• Why are chloroplasts not found in animal cells?

  Because animal cells do not perform photosynthesis
• What is the primary function of the cell membrane?

  To control the movement of substances
• What is the role of the cytoplasm in cellular functions?

  It is the site of chemical reactions
• What is the function of the nucleus in a cell?

  It controls the cell's activities
• How do mitochondria function in both plant and animal cells?

  They produce energy through aerobic respiration
• What is the primary role of the cell wall in plant cells?

  To provide structure and support
