Questions and Answers

What is the primary function of meristematic tissue in plants?

  • To facilitate gas exchange
  • To continually divide and contribute to plant growth (correct)
  • To store water and nutrients
  • To provide structural support

Where are meristematic tissues typically found in plants?

  • In the roots and shoot tips (correct)
  • In the leaves
  • In the stem
  • In the flowers

What are the main characteristics of cells in meristematic tissue?

  • Irregular-shaped cells with no specific characteristics
  • Large, thick-walled cells with small nuclei and large vacuoles
