MCQ
What is common between chloroplasts, chromoplasts and leucoplasts ?
- APresence of pigments
- BPossession of thylakoids and grana
- ✓Storage of starch, proteins and lipids.
- DAbility to multiply by a fission-like process
✓
Answer
Correct option: C.
Storage of starch, proteins and lipids.
c
Chromoplasts are plastids responsible for pigment synthesis and storage. They, like all other plastids (including chloroplasts and leucoplasts), are organelles found in specific photosynthetic eukaryotic species. Chloroplasts conduct photosynthesis. Chloroplasts absorb light and use it in conjunction with water and carbon dioxide to produce sugars. Leucoplasts are non-pigmented, in contrast to other plastids such as the chloroplast. Lacking pigments, leucoplasts are not green, so they are predictably located in roots and non-photosynthetic tissues of plants. They may become specialized for bulk storage of starch, lipid or protein and are then known as amyloplasts, elaioplasts, or proteinoplasts respectively
