cells

• Cell Membrane


  Acts as a barrier, regulating what enters and exits the cell. Maintains the integrity of the cell and supports communication and signaling between cells.
• Cell Membrane


  • It is the outermost layer in animal cells and lies just inside the cell wall in plant cells.
• Cell Wall


  Provides structural support and protection. Helps maintain the shape of the cell and prevents excessive water uptake.
• Cell Wall


  • It is found outside the cell membrane in plant cells, fungi, and some prokaryotes. It is not present in animal cells.
• Mitochondria


  Generate ATP through cellular respiration, providing energy for the cell's activities.
• Mitochondria


  • Scattered throughout the cytoplasm in eukaryotic cells.
• Cytoplasm


  A jelly-like substance that fills the cell, providing a medium for chemical reactions to take place and supporting organelles.
• Cytoplasm


  • It occupies the space between the cell membrane and the nucleus in eukaryotic cells.
• Nucleus


  Houses the cell's genetic material (DNA) and controls cellular activities by regulating gene expression. It is the command center of the cell.
• Nucleus


  • Typically located in the central region of eukaryotic cells.
• Vacuole


  Storage organelles that can hold various substances such as nutrients, waste products, or water. In plant cells, the central vacuole also helps maintain turgor pressure, which supports the cell's structure.
• Vacuole


  • In plant cells, there is usually one large central vacuole. In animal cells, vacuoles are smaller and more numerous.
• Summary


  • Cell Membrane: Barrier and regulator, present in all cells.
  • Cell Wall: Structural support, present in plant cells, fungi, and some prokaryotes.
  • Mitochondria: Energy production, present in eukaryotic cells.
  • Cytoplasm: Medium for reactions, present in all cells.
  • Nucleus: Genetic control center, present in eukaryotic cells.
  • Vacuole: Storage and structural support, prominent in plant cells and smaller in animal cells.
