Overview

• Topic: Plant and Animal Cells
• Focus on similarities and differences between the two types of cells.

Key Features of Cells

Similarities

• Both plant and animal cells have:
  • Cell Membrane: Allows selective entry and exit of substances.
  • Cytoplasm: Jelly-like substance containing organelles.
  • Nucleus: Control center containing genetic material (DNA).
  • Ribosomes: Responsible for protein synthesis.
  • Mitochondria: Energy production.

Differences

• Cell Wall:
  • Only found in plant cells, made of cellulose, helps maintain shape.
• Vacuoles:
  • Large in plant cells (mainly for water storage), small in animal cells (for digestion and waste removal).
• Centrioles:
  • Present only in animal cells, assist in cell division.
• Chloroplasts:
  • Found in plant cells, contain chlorophyll for photosynthesis.
• Lysosomes:
  • Common in animal cells for waste disposal, less common in plant cells.

Organelles in Detail

• Golgi Bodies:
  • Package proteins made by ribosomes for transport.
• Endoplasmic Reticulum (ER):
  • Transportation network for protein packages; can be rough (with ribosomes) or smooth.

Summary of Differences

• Plant Cell:
  • Has cell wall, chloroplasts, and large vacuoles.
• Animal Cell:
  • Has centrioles and lysosomes, smaller vacuoles.

Conclusion

• Importance of understanding cell structures for biological functions.
