Question

which cell organelle reduces the number of other cell organelles

Answer 1

Hii there!!

I think Lysosomes reduce the number of other cell organelles if they find that a particular cell organelle is damaged.
If the damaged organelle is not killed by the Lysosomes, it can affect the cell and then the body.

Hope it helps....

Answer 2

It's Lysosomes.

Lysosomes destroy the foreign substances and help in intracellular digestion also.
