Consider the following statements A. In prokaryotic cells a special membranous structure formed by the extension of the plasma membrane into the cell is known as polysome B. The smooth endoplasmic reticulum is the major site for synthesis of glycoproteins C. RuBisCo is the most abundant protein in the whole of biospshere D. Mitochondria, chloroplasts and peroxisomes are not considered as part of endomembrane system Of the above statements

Assertion:- Mitochondria, chloroplast and peroxisome are not involved in endomembrane system. Reason:- Their functions are not coordinated with constituents of endomembrane system.

Enzymes required for synthesis of carbohydrates and Proteins are present in (A) Mitochondria (B) Chloroplast (C) Centrosome (D) A&B

Mitochondria and Chloroplasts are similar in having- (a) two membranes (b) Cristae ( c ) DNA (d) Ribosomes ( e ) Thylakoids

Assertion : The endomembrane system includes endoplasmic reticulum (ER), Golgi complex, lysosomes and vacuoles. Reason : Mitochondria, chloroplast and peroxisomes are not the part of endomembrane system because their functions are coordinated with the same.

Correct statement regarding Mitochondria and Chloroplast I) ATP synthesis is seen in both II) Outer membrane has more surface in both III) Circular naked DNA,RNA and 70 S ribosomes are seen in both IV) Oxidative phosphorylation occurs in both
