cell biology : plant cells

• What should you be able to do by the end of the video on plant cells?

  Correctly label a diagram of a plant cell and describe the functions of its parts
• What is a key difference between plant cells and animal cells regarding shape?

  Plant cells have a regular shape, while animal cells can change shape
• What do plant cells contain that gives them their green color?

  Chloroplasts
• What is the function of chloroplasts in plant cells?

  They are the sites of photosynthesis
• What are the common structures found in both plant and animal cells?

  Nucleus, cytoplasm, cell membrane, mitochondria, and ribosomes
• What is the role of the nucleus in a plant cell?

  It contains genetic material
• What is the function of the cytoplasm in a plant cell?

  It is where chemical reactions take place
• What does the cell membrane do in a plant cell?

  It controls which molecules enter and leave the cell
• What is the function of mitochondria in plant cells?

  They carry out aerobic respiration
• What are ribosomes responsible for in plant cells?

  Protein synthesis
• What are the three structures that plant cells have which animal cells do not?

  Chloroplasts, cell wall, and large permanent vacuole
• What is the role of chlorophyll in chloroplasts?

  It is essential for photosynthesis
• What is the composition of the cell wall in plant cells?

  It is made from cellulose
• How does the vacuole contribute to the shape of a plant cell?

  It is filled with fluid, helping to maintain the cell's shape
• What is the fluid inside the vacuole of a plant cell called?

  Cell sap
• What are the main features of plant cells compared to animal cells?

  • Regular shape
  • Contain chloroplasts for photosynthesis
  • Have a cell wall made of cellulose
  • Large permanent vacuole filled with cell sap
• What should you do to prepare for questions on plant cells in your exam?

  • Practice labeling diagrams of plant cells
  • Describe the functions of different parts of a plant cell
  • Review the differences between plant and animal cells
