Cell structure and the cell cycle

Where are the chloroplasts?

  • Plastids
    • Chloroplasts
    • Leucoplasts
      • Amylopasts
      • Elaioplasts (niyb)

Plastids - Chromoplasts

Chloroplast Genome

  • Circular DNA molecule
  • Replicate independently
  • Sequence characteristics resembles that of bacteria

Paramecium with endosymbiont

Chlorella

Cell walls

  • Pectins (proteins) and hemicelluloses (carbohydrates) link cellulose molecules together

Cell Walls

  • Lignin strengthens & waterproofs secondary cell walls

Bordered pits

Plant cell connections

  • Plasmodesmata provide cytoplasmic connections between cells

Cytoskeleton

  • Microtubules
  • Microfilaments
  • Motor proteins (walking molecules)

Movement in plant cells and the

cytoskeleton
