mitosis

• DNA is found inside the nucleus, which contains genetic information that controls all activities within the cell.
• The nucleus is the control center of the cell.
• Mitochondria are responsible for producing energy through respiration.
• Ribosomes synthesize proteins using instructions from DNA.
• Lysosomes contain enzymes that break down waste materials.
• Ribosomes are involved in protein synthesis.
• Mitochondria are responsible for producing energy through cellular respiration.
• The cytoplasm is where most chemical reactions take place, including protein synthesis.
• Mitosis


  1. Prophase

  2. Metaphase

  3. Anaphase

  4. Telophase

  5. Cytokinesis
• Mitosis


  Process of cell division that makes possible regeneration of body parts
• Interphase


  Period of growth and rest before a dividing cell enters mitosis
• Prophase


  • Chromatin condenses and becomes short and thick to form chromosomes
  • Each chromosome has two sister chromatids joined together at the centromere
  • Nucleolus disappears and nuclear membrane starts to break down
  • Centrosomes move apart to opposite poles forming a spindle
• Metaphase


  • Microtubules of the spindle interact with chromosomes
  • Chromosomes move and align along the middle of the cell or the equatorial plate
  • Sister chromatids are held at the centromere by kinetochores
• Anaphase


  • Sister chromatids separate at the kinetochore
  • Daughter chromosomes along with divided centromere move towards opposite poles
  • Microtubules shorten and poles of the spindle move apart to help separate the chromosomes
• Telophase


  • Daughter chromosomes arrive at the poles
  • Chromatin starts to decondense
  • Nuclei and nucleoli reform
  • Nuclear membrane reforms
• Cytokinesis


  • In animals, a cleavage furrow forms in the plasma membrane which deepens and divides the cell
  • In plants, a cell plate forms at the center and grows outwards to meet the existing cell wall
• Cytoskeleton provides structure and support to the cell.
• Cell membrane regulates what enters or leaves the cell.
• Cell membrane regulates what enters or leaves the cell.
• Cytoskeleton provides structure to the cell and helps with movement.
