Read the following statements carefully: (A) In animal cells, lipid-like steroidal hormones are synthesized in the smooth endoplasmic reticulum. (B) The isolated lysosomal vesicles have been found to be very rich in almost all types of hydrolytic enzymes, optimally active at the basic pH. (C) In plants, the tonoplast facilitates the transport of a number of ions and other materials against concentration gradients int

Step-by-step solution

Statement (A) is correct as the smooth endoplasmic reticulum (SER) is the major site for the synthesis of lipids, including lipid-like steroidal hormones in animal cells. Statement (B) is incorrect because lysosomal enzymes (hydrolases) are optimally active at an acidic pH, not a basic pH. Statement (C) is correct because the tonoplast (vacuolar membrane) actively transports ions and other materials against their concentration gradients into the vacuole, making their concentration higher in the vacuole than in the
