2. Cytoplasm: It assists in holding the organelles of the cells in place.  

3. Cell wall: It is the main safeguarding barrier of the plant cells.  

4. Chloroplast: It transforms sunlight into energy by a procedure known as photosynthesis.  

5. Cytoskeleton: It provides structural support for the cell.

12. Golgi Apparatus: It transforms proteins and fats built in the cell and transports them outside the cell or prepares them for storage.  

13. Plasmodesmata: It allows communication and transport of substances to the nearby cells.  

14. Vacuole: It stores waste components and sustains the level of pH of the cell.
