Consider the following statement (a) Endomembrane system includes mitochondria , chloroplast and peroxisomes (b) Smooth endoplasmic reticulum is major site for synthesis of lipid (c) Rough endoplamic reticulum is actually involved in protein synthesis (d) Mitchondrial matrix possesses single cirular DNA , a few RNAs and 80 S ribosomes Of the above statements

How many statements are not incorrect ? (1) schleiden gave the cell hypothesis. (2) Golgi bodies are extensive and continuous with the outer membrane of the nucleus . (3) Endomembranous system contains vacuoles (4) Peroxisome coordinates with Golgi bodies .

Go through the following statements (i) In human beings, the membrane of the erythrocyte has approximately 52 percent lipids and 40 percent proteins (ii) Lipids are arranged within the membrane with the hydrophobic tails towards the outer side and the polar head towards the inner side. (iii) As the polar molecules cannot pass through the non- polar lipid bilayer, they require a carrier protein of the membrane to facilitate their transport across the membrane (iv) The endomembrane system includes endoplasmic reticulum, Golgi complex, lysosomes and peroxisomes Find out the wrong peroxisomes :
