Questions & Answers about nobiru ni tsurete, shichuu ga hitsuyou ni naru.

What does に つれて mean here?

に つれて means as something happens, in proportion as, or along with.

So 伸びる に つれて means:

• as it grows
• as it gets longer
• as growth progresses

This pattern is used when one change happens alongside another change.

In this sentence:

• the plant or stem grows
• and, as a result, a support becomes necessary

So the sentence describes two linked changes happening together.

Why is 伸びる in the dictionary form?

Before に つれて, verbs normally appear in the plain dictionary form.

So:

• 伸びる に つれて = as it grows
• not 伸びて に つれて

This is just the standard grammar pattern:

• verb dictionary form + に つれて
• noun + に つれて

Examples:

• 年を取るにつれて = as one gets older
• 日本語が上手になるにつれて = as one gets better at Japanese

So 伸びる is not especially informal here; it is just the required form for this grammar.
