Answer 2

Answer:

1. Master of the cell                              -         d. Nucleus

2. Powerhouse of the cell                    -         c. Mitochondria

3. Protein factories of the cell              -         e. ribosomes

4. Kitchen of the cell                             -         a. chloroplast

5. Circulatory system of the cell           -         b. endoplasmic reticulum

Explanation:

• The master of the cell is the nucleus as it is the ‘control center’ and controls cellular activities like reproduction, metabolism, etc.
• The “powerhouse of the cell” is the mitochondria because it stores the energy molecules, and the ATP.
• The protein factories of the cell are the ribosomes which synthesizes chains of protein molecules with the amino acids  
• Kitchen of the cell is the chloroplast because they contain cholorphyll, the green pigment; with the help of which all plants “produce their own food”.
• The circulatory system of the cell is the endoplasmic reticulum because it helps in “transportation of the materials” throughout the cell.
