Question

Your friend thinks that plants are not alive because they do not move. How would you respond to your friend?

Answer 1

They are not correct.

Explanation:

Plants are alive because they have cells inside them, and obey all of the seven characteristics of living things. A common mnemonic for that is `"MRS. GREN"`.

`"M"` is for movement

First `"R"` is for respiration

`"S"` is for sensitivity

`"G"` is for growth

Second `"R"` is for reproduction

`"E"` is for excretion

`"N"` is for nutrition

Anything that has living cells inside them is considered to be alive. Also, plants can still move, as in the case of seeds, and they also face the sunlight during their growth.

Just because we see them not move on the outside, doesn't mean that they don't move inside. Think of the phrase, Don't judge a book by its cover.
So, in general, my friend will not be correct.
