Q. Choose the correct statement from the codes given below I. Separation from extracellular medium allows the cells to maintain its chemical pool, orderliness of structure and reactions in contrast to disorderly distribution and randomly interacting molecules in the extra-cellular medium II. Cells are unable to recognise one another due to the present of specific chemicals on their surface III. Cells of plant tissues are often connected with one another through cytoplasmic bridges called plasmodesmata IV. Different cells of an organism communicate as well as exchange materials with one another
A) II and III
B) I and II
C) I, III and IV
D) I, II, III and IV
Explanation
The ability to distinguish different neighbouring cells is important for organism’s function Glycolipids are lipids with attached carbohydrate, which acts as recognition sites during cell-cell interaction, as well as sites of attachment in a tissue Glycoproteins are often integral membrane proteins and are also important for cell recognition
