Plant & Animal Cells

• What are the two main types of cells mentioned in the study material?

  Plant cells and animal cells
• What do animal cells and plant cells have in common?

  They have some parts in common that have particular functions
• What are the three structures found in most plant cells but not in animal cells?

  • Chloroplasts
  • Cell wall
  • Large central vacuole
• What is the function of chloroplasts in plant cells?

  Chloroplasts are where photosynthesis takes place to make food for the plant cell
• What is the role of the cell wall in plant cells?

  The cell wall helps support the cell and keeps its shape
• What does the large central vacuole contain and what is its function?

  The large central vacuole contains cell sap which helps keep the plant cell rigid
• Why do muscle cells contain more mitochondria than skin cells?

  Muscle cells require more energy for contraction
• How do plants stand upright without skeletons?

  Plants stand upright due to turgor pressure from the large central vacuole
• Why do not all plant cells have chloroplasts?

  Not all plant cells are involved in photosynthesis
• What is one similarity between a bacterial cell and an animal cell?

  Both are types of cells
• What is one difference between a bacterial cell and an animal cell?

  Bacterial cells do not have a nucleus, while animal cells do
• How is the shape of a root hair cell suited to its function?

  The shape increases surface area for water absorption
• How does the shape of a root hair cell differ from other cells, and why is this an advantage?

  Root hair cells are elongated, which increases surface area for absorption
• If the image of a bacterium is 1.2 cm long, how do you calculate the magnification?

  Magnification = image length / actual length
• What are the key components of a plant cell that differentiate it from an animal cell?

  • Chloroplasts for photosynthesis
  • Cell wall for support and shape
  • Large central vacuole for rigidity
