11.6 cell death is important in living organisms

Question 1

Cell Death: Necrosis

Answer 1

Explanation: Necrosis is cell death due to damage or deprivation of oxygen/nutrients. The cell swells, bursts, releasing contents, causing inflammation.

Question 2

Cell Death: Apoptosis

Answer 2

Explanation: Apoptosis is programmed cell death for unneeded or genetically damaged cells, preventing cancer risk.

Question 3

Events of Apoptosis

Answer 3

Explanation: Apoptosis involves cell detachment, chromatin digestion, bleb formation, and engulfment by neighboring cells.

Question 4

Necrosis: Cell Bursting

Answer 4

Explanation: Necrosis results in cell swelling and bursting, releasing contents and inducing inflammation.

Question 5

Necrosis vs. Apoptosis

Answer 5

Explanation: Necrosis is uncontrolled cell death, while apoptosis is programmed and essential for tissue balance.

Question 6

Apoptosis: Cell Fragmentation

Answer 6

Explanation: Apoptotic cells form blebs, break into fragments, and are recycled by neighboring cells.

Question 7

Apoptosis: Programmed Cell Death

Answer 7

Explanation: Apoptosis is a regulated process, eliminating unnecessary or harmful cells, preventing cancer and maintaining tissue integrity.
