animal and plant cells

• What are cells often referred to as?


  Building blocks of life
• What are the basic components of all cells?

  • Cell membrane
  • Cytoplasm
  • Nucleus
  • Mitochondria
  • Ribosomes
• What is the function of the cell membrane?


  It is a selectively permeable barrier that surrounds the cell.
• What is contained within the nucleus of a cell?


  Genetic material (DNA)
• What is the role of mitochondria in a cell?


  They produce energy for the cell.
• What do ribosomes do?


  They synthesize proteins.
• Which organelle is responsible for modifying and packaging proteins?


  The Golgi apparatus
• What are the common structures found in both animal and plant cells?

  • Cell membrane
  • Cytoplasm
  • Nucleus
  • Mitochondria
  • Ribosomes
  • Endoplasmic reticulum
  • Golgi apparatus
• What is the function of lysosomes in animal cells?


  They contain enzymes for breaking down cellular waste.
• What are centrioles involved in?


  Cell division
• What is a key characteristic of animal cells compared to plant cells?


  Animal cells are generally smaller and have an irregular shape.
• What structure is unique to plant cells that provides support?

  Cell wall
• What is the function of chloroplasts in plant cells?


  They are responsible for photosynthesis.
• What is the large central vacuole in plant cells used for?


  It stores water, nutrients, and waste products.
• What are the similarities and differences between animal and plant cells?

  Similarities:

  • Both have a cell membrane, cytoplasm, nucleus, mitochondria, and ribosomes.
  • Both perform respiration and protein synthesis.

  
  

  Differences:

  • Plant cells have a cell wall and chloroplasts; animal cells do not.
  • Plant cells have a large central vacuole; animal cells have a small or absent vacuole.
  • Plant cells are generally larger and have a rectangular shape; animal cells are smaller and irregular.
  • Plants store energy as starch; animals store it as glycogen.
• Which type of cell stores energy as starch?


  Plant cells
• What is a key difference in the shape of animal and plant cells?


  Plant cells are usually rectangular, while animal cells are often irregular.
• What is the role of the endoplasmic reticulum in a cell?


  It transports materials within the cell.
• What is the function of the Golgi apparatus?


  It modifies, packages, and distributes proteins.
• How do lysosomes and mitochondria differ in function within animal cells?


  Lysosomes break down waste, while mitochondria produce energy.
• What is the significance of chlorophyll in chloroplasts?


  Chlorophyll is essential for photosynthesis as it captures light energy.
• Why do plant cells have a more rigid shape compared to animal cells?


  Because of the presence of a cell wall.
• What is the primary role of ribosomes in both animal and plant cells?


  To synthesize proteins.
• How does the presence of a central vacuole affect the function of plant cells?


  It helps maintain turgor pressure and stores essential substances.
