Plant cells are eukaryotic cells that differ in several key aspects from the cells of other eukaryotic organisms. Their distinctive features include:


  • A large central vacuole
  • A cell wall composed of cellulose and hemicellulose
  • Specialized cell-to-cell communication pathways known as plasmodesmata
  • Plastids, the most notable being the chloroplast, which contains chlorophyll
  • Cell division by construction of a phragmoplast
  • The sperm of bryophytes and pteridophytes, Cycads and Ginkgo have flagella
