Cell: The Unit Of Life

Question 1

An improved model of the structure of cell membrane was proposed by?

Answer 1

Singer and Nicolson (1972) widely accepted as fluid mosaic model

Question 2

Whats fluid mosaic model?

Answer 2

The quasi-fluid nature of lipid enables
lateral movement of proteins within the overall bilayer.
This ability to move within the membrane is measured as its fluidity.

Question 3

fluid nature of the cell membrane importance

Answer 3

1. cell growth,
2. formation of intercellular junctions,
3. secretion,
4. endocytosis,
5. cell division

TRICK

Cats → Cell Growth
(Picture a cat growing into a giant fluffy monster. More cat = more growth! 🐱)

Freaking → Formation of Intercellular Junctions
(Imagine a bunch of cats trying to link paws together to form a solid wall of fluff—junctions of fur! 🐾)

Sneeze → Secretion
(A sneezy cat releases all sorts of stuff! Maybe even a tiny cloud of fur, dust, and pollen. Secretion! 🤧)

Every → Endocytosis
(The cat sucks in everything around it—treats, toys, even the crumbs under the couch—endocytosis in action! 🐱🍖)

Day → Cell Division
(Every day, this cat goes through division—splitting into two or more cats, just to keep you on your toes. More cats, more fun! 🐈🐈)
