Question
Fluidity of cell membrane helps in(a) Cell growth (b) Formation of intercellular junctions (c) Endocytosis & Secretion
Solution
The fluidity of the cell membrane plays a crucial role in various cellular processes:
(a) Cell growth: The fluid nature of the cell membrane allows it to expand and grow as the cell grows. The lipids in the cell membrane can move, rotate and flex, allowing the membrane to change shape and size.
(b) Formation of intercellular junctions: The fluidity of the cell membrane allows proteins to move within the membrane to form junctions with other cells. These junctions are important for communication and transport between cells.
(c) Endocytosis & Secretion: The fluidity of the cell membrane allows it to bend and fold, which is necessary for endocytosis (the process by which cells absorb molecules by engulfing them) and secretion (the process by which substances are produced and discharged from a cell). The membrane can form a vesicle to enclose substances for endocytosis or open to release substances for secretion.
So, the fluidity of the cell membrane helps in all of the above processes - cell growth, formation of intercellular junctions, and endocytosis & secretion.

Endocytosis is a cellular process that is generally responsible for membrane receptor internalization, nutrient uptake, and the regulation of cell signaling. Microorganisms (many bacteria and viruses) and toxins also internalize and enter the cells.
