-Plural nouns do not require an apostrophe.
-Example: The plants look green today.
-Singular possessive nouns require an apostrophe

-this rule also applies if the singular possessive noun ends with an s
Plural possessive nouns require apostrophes if they end with an s. (If the plural noun doesn’t already end with an s the apostrophe comes before the s you need to add). If the pluralnoun already has an s, the apostrophe comes after the s.
