(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 presence of specific chemicals on their surface. |
(iii) Cells of plant tissue 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) (iii) and (iv)
C) (i),(iii) and (iv)
D) (i), (ii), (iii) and (iv)
Correct Answer: C

Glycoproteins are often integral membrane proteins and are also important for cell recognition.You need to login to perform this action.
