Cells can be either prokaryotic or eukaryotic. Eukaryotic cells are more complex with a nucleus, like all animal and plant cells. Prokaryotes are less complex and don't have a nucleus, for example a bacterial cell. They both contain subcellular structures.

Plant cells are made up of:

  • vacuoles- contains cell sap and maintains pressure to support the cell
  • chloroplasts- where photosynthesis occurs, contains chloropyll which absorbs needed light
  • cytoplasm- where chemical reactions happen
  • cell membrane- cholds cell together, controls what comes in and out
  • cell wall- rigid structure made of cellulose, supports and strengthens…
