Question

All of the following are part of a prokaryotic cell expect A) DNA B) a cell wall. C) a plasma membrane D) ribosomes. E) an endoplasmic reticulum. Prokaryotes are classified as belonging to two different domains. What are the domains? A) Bacteria and Eukarya B) Bacteria and Archaca C) Archaea and Protista D) Bacteria and Protista E) Bacteria and Fungi Which organelle or structure is absent in plant cells? A) mitochondria B) Golgi vesicles C) microtubules D) centrosomes E) peroxisomes Large numbers of ribosomes are present in cells that specialize in producing which of the following molecules? A) lipids B) glycogen C) proteins D) cellulose E) nucleic acids Which type of organelle or structure is primarily involved in the synthesis of oils, phospholipids, and steroids? A) ribosome B) lysosome C) smooth endoplasmic reticulum D) mitochondrion E) contractile vacuole The Golgi apparatus has a polarity or sidedness to its structure and function. Which of the following statements correctly describes this polarity? A) Transport vesicles fuse with one side of the Golgi and leave from the opposite side. B) Proteins in the membrane of the Golgi may be sorted and modified as they move from one side of the Golgi to the other. C) Lipids in the membrane of the Golgi may be sorted and modified as they move from one side

Explanation / Answer

Endoplasmic reticulum is absent in the prokaryotes (e) Prokaryotes ate clasaified under two domains i.e. Bacteria and Archaea. (b) Microtubules are absent in plant cells. (c) Ribosomes are specialized for protein synthesis. (c) Smooth endoplasmic reticulum is involved in the synthesis of oils, phospholipids and steroids. Transport vesicles fuse with the one side of golgi and leave from the opposite side explains the polarity of GA.
