plant cells

• A double membrane organelle (used to make and store STARCH) = amyloplasts are not found in animal cells
• plant cell vs animal

  p = cell wall, a= no cell wall

  p= chloroplast, a = no chloroplasts

  p= no centrioles, a= centrioles

  p = energy storage is starch, a= energy storage is glycogen
• chloroplasts

  • site of photosynthesis - light energy is absorbed by chlorophyll and used to produce glucose from water and carbon dioxide
• chloroplasts features

  • Granum - stack of thylakoids
  • thylakoids - contains chlorophyll pigments for photosynthesis
  • starch - energy storage molecule in plants
  • DNA and ribosomes - chloroplasts have their own DNA and 70s ribosomes to make enzymes needed for photosynthesis
• Cell wall - made up of cellulose. Protects and supports cell
• • Channels called plasmodesmata allow transport and communication between individual plant cells
  • Vacuole contains cell sap which helps maintain turgor pressure. This ensures a rigid framework of the cell.
