  • Plants are composed of microscopic living units called cells.
  • All parts of a plant, including flowers, grass, and trees, are made up of cells.
  • Plant cells share many organelles with animal cells, such as the nucleus, cytoplasm, cell membrane, mitochondria, and ribosomes.
  • Plant cells have additional organelles not found in animal cells, including a cell wall made of cellulose which provides protection and shape.
  • Plant cells often have a permanent vacuole that stores cell sap and helps maintain cell shape.
  • Most plant cells contain chloroplasts with chlorophyll, which is responsible for the green color and plays a crucial role in photosynthesis.
  • Plant cells can be observed in detail using an electron microscope, and their structures can be identified in exams through simple drawings or images.
  • The cell wall is the outermost layer of the plant cell, followed by the cell membrane, and the vacuole is typically located between these structures.
  • The cytoplasm contains ribosomes and other organelles like mitochondria and the nucleus can be identified in images of plant cells.
