Question Detail
Question
Which part of the plant is primarily responsible for primary growth?
Correct Answer
Option D is the correct answer.
Detailed Explanation
Apical meristems are located at the tips of roots and shoots and are responsible for primary growth, which increases the length of the plant. Lateral meristems (like cork cambium) are responsible for secondary growth, which increases girth.
Hint
Think about the parts of the plant that enable it to grow taller or roots longer.
