Question

cell division is essential for any living organism. for which of these processes is it not absolutely necessary?
a) tissue renewal
b) growth and development
c) reproduction
d) preservation

Explanation:

• Tissue renewal relies on cell division to replace old/damaged cells.
• Growth and development require cell division to increase cell number and form structures.
• Reproduction uses cell division (mitosis for asexual, meiosis + mitosis for sexual) to create new organisms.
• Preservation (maintaining an organism's state without active growth/repair) does not require cell division; it can occur via static, non-dividing states (e.g., dormancy).

Answer:

d) Preservation
