b. Free ribosomes	2. Take part in osmoregulation and excretion
c. Mitrochondrion	3. Synthesize lipids
d. Contractile vacuole	4. Synthesize non secretory proteins

• A. a- 3, b- 4, c- 1, d- 2
• B. a- 1, b- 2, c- 4, d- 3
• C. a- 3, b- 4, c- 2, d- 1
• D. a- 3, b- 2, c- 1, d- 4

Answer 1

Answer: (A)

a- 3, b- 4, c- 1, d- 2

Smooth endoplasmic reticulum does not have ribosomes on their surface and involved in producing lipids. SER also take part in detoxification. Mitochondria is a large double membrane bound cell organelle involved in aerobic respiration and produces energy in the form of ATP.
The contractile vacuole is seen in some protists and is involved in osmoregulation. They pick up water from surrounding cytoplasm, expand and collapse to throw out water to the outside.
The free ribosomes translate the genetic message encoded in mRNA and synthesize peptide units.
So, the correct answer is option A.
