The lysosome of a plant cell and the Car alarm perform similar functions in their respective systems!
Lysosomes digest foreign particles and bacteria and gets rid of unwanted substances. Likewise, The Car alarm rings when there is an intruder; a thief who wants to steal something. It alerts the car owner and in a way helps “get rid” of something unwelcomed, in this case the thief.
However, lysosomes are directly involved in the digestion of bacteria in the cell while the car alarm only plays a part in the process. The person directly involved is the driver himself, who will have to deal with the intruder; the thief.
