Per NCERT, what is CONTACT INHIBITION in animal cells?
AA process where cell division STOPS when cells come into contact with neighbouring cells — preventing uncontrolled growth
BA process where cells reproduce faster on contact
CA process where cells die on touch
DA process where cells fuse on contact
Answer & Solution
Correct answer: A. A process where cell division STOPS when cells come into contact with neighbouring cells — preventing uncontrolled growth
Per NCERT §2.5.1, contact inhibition stops cell division when cells touch — a control mechanism lost in cancer cells. The other options misstate.
