Answer:
The correct answer will be 
1. Enzyme
2. Plastid
3. Lysosome
4. Mitochondrion
5. An Organelle
6. Golgi apparatus
7. Vesicles
Step-by-step explanation:
1. Enzyme: The chemical structures which catalyse the biological reactions and increasing the rate of reaction by lowering the amount of activation energy. 
2. Plastids- the organelle formed which perform different functions in the cell on the basis of which they are given the names like amyloplast store the starch. 
3. Lysosome- the organelle which stores the variety of digestive enzymes and marked by the highly acidic conditions. 
4. Mitochondria- The double membrane structure associated with the production of energy molecule called ATP which is utilized during the other metabolic process. 
5. Organelle- The compartmentalized structures of the cell which perform various functions needed to survive. 
6. Golgi apparatus- The apparatus which is programmed to package and modify the gene expressed products. 
7. Vesicles- the associated structure of the Golgi apparatus and the endoplasmic reticulum in the cell which transports the material to and fro in the endomembrane system.
