  1. DNA
  2. Chlorophyll
  3. Cellulose
  4. Adenosine Triphosphate (ATP)
Show answer and solution

Correct answer: D. Adenosine Triphosphate (ATP)

As per your syllabus, which plastid contains pigments OTHER than chlorophyll (yellow, orange, red) — giving colour to flowers and fruits?

  1. Leucoplasts
  2. Mitochondria
  3. Chromoplasts
  4. Chloroplasts
Show answer and solution

Correct answer: C. Chromoplasts

As per your syllabus, chromoplasts contain non-chlorophyll pigments — basis of flower / fruit colour. Chloroplasts are green leucoplasts are colourless mitochondria aren't plastids.
