1. Which of the following describes how a plant grows?
O A plant grows continuously throughout its life.
A plant stops growing at about the age of 20.
O A plant grows until it doubles the height it was at one year old.
O A plant grows for 100 years.

A plant grows continuously throughout its life.

Explanation:

Unlike humans, plants grow endlessly throughout their lives. This is because their growth is supported by "cell growth" and "cell division." The size of the plant's cell increases through cell growth while the number of its cells increases through cell division. This cell division is also known as "mitosis."

The plant's "meristem" is also considered to be a factor on why plants can grow continuously throughout its life. This tissue allows the cells in the plants to undergo cell division.
