Cell structure

• Cells are the smallest unit of life and the building blocks for all organisms
• Each component of a cell has its own function
• Animal and plant cells differ and they have similarities
• Cell components found in both animal and plant cells

  • Nucleus
  • Cell membrane
  • Cytoplasm
  • Mitochondria
• Animal cells


  • Often have an irregular shape
• Nucleus


  Contains the genetic material (DNA) of the organism and controls the cell's activities
• Cytoplasm


  The liquid that makes up most of the cell in which chemical reactions happen
• Cell membrane


  A flexible outer layer that surrounds the cell and controls which substances can pass into and out from it
• Mitochondria


  Tiny parts of cells floating in the cytoplasm where energy is released from glucose from food
• Plant cells


  • Often have a regular shape
• Additional components of plant cells

  • Cell wall
  • Vacuole
  • Chloroplasts
• Cell wall


  A tough outer layer of the cell, which contains cellulose to provide strength and support to the plant
• Vacuole


  A space inside the cytoplasm that contains a watery liquid called cell sap, which keeps the cell firm
• Chloroplasts


  Structures found in the cells of green parts of plants only (leaves and stems) which contain a green pigment called chlorophyll in which photosynthesis occurs
