Important Questions on Cell: The Unit of Life
Read the given statements and select the correct option.
Statement 1: Peroxisomes are involved in photorespiration of the plant cells and help in the lipid metabolism of animal cells.
Statement 2: They are the cell's garbage disposal system.



A red blood corpuscle (RBC) was kept in a solution and treated so that it became inside-out. What will be the polarity of the phospholipid bilayer in this cell?

A student made a pictorial representation of a eukaryotic cell membrane and labelled the components as follows.
The student has made errors while labelling the components of membrane. Which of the following hold true regarding the error?
(i) Protein A should be labelled as trans-membrane protein only and not as integral protein.
(ii) The polarity of the protein should be reversed because the cytosolic phase always shows reducing environment.
(iii) Position of cholesterol molecule should be close to polar region as it contains a polar group.
(iv) Protein should be labelled as integral membrane protein and not as peripheral glycoprotein.



(i) The surface area available for cellular functions in a prokaryotic cell is less than that in a eukaryotic cell.
(ii) The total genome size of a prokaryotic cell is always less than that of a eukaryotic cell.
(iii) Unlike eukaryotes, no special respiratory organelles are found in prokaryotes. Hence, they respire at a much lesser rate than eukaryotes.
(iv) Eukaryotic cells show various membrane bound organelles such as chloroplasts and nucleus while ribosomes are the only membrane bound organelles found in prokaryotes.
