Worked practice questions

A group of cells of similar structure that work together to perform a specific function is called a:

  1. Organ system
  2. Organ
  3. Tissue
  4. Organism
Show answer and solution

Correct answer: C. Tissue

A tissue is a group of structurally similar cells specialised to perform a particular function — like muscle tissue (movement), nervous tissue (signal conduction), or epidermis (protection). Tissues combine to form organs.

Which plant tissue is responsible for ACTIVE cell division (growth)?

  1. Meristem
  2. Parenchyma
  3. Phloem
  4. Sclerenchyma
Show answer and solution

Correct answer: A. Meristem

Meristematic tissue consists of small, actively dividing cells. Their division produces new cells that later differentiate into permanent tissues. Meristems are responsible for plant growth — vertical (apical), girth (lateral), and regrowth after cutting (intercalary).

Roots grow longer because of cell division in the:

  1. Apical meristem (at the root tip)
  2. Lateral meristem
  3. Intercalary meristem
  4. Phloem
Show answer and solution

Correct answer: A. Apical meristem (at the root tip)

Apical meristems sit at the tips of roots and shoots. Their division pushes the tip forward (in roots: downward into the soil), increasing length. If you cut off the root tip, longitudinal growth stops — which is why pruning a plant tip stunts vertical growth.
