GeneralClass 10CBSEAnswered 1 Apr 2026
Answer
For Class 9 biology curriculum, plastids are located in the cytoplasm of plant cells, primarily in leaf mesophyll cells, fruit tissues, root storage cells, and developing seeds.
Location by Tissue Type:
Green Plant Parts (Chloroplasts):
- Leaf mesophyll cells (highest concentration)
- Young stems and unripe fruits
- Guard cells surrounding stomata
Non-Green Plant Parts:
- Roots: Leucoplasts store starch (amyloplasts)
- Ripe Fruits: Chromoplasts create red, yellow, orange colors
- Flowers: Chromoplasts attract pollinators with bright pigments
- Seeds: Amyloplasts store energy reserves
Important Notes::
- Plastids adapt to specific tissue needs
- Location determines plastid type and function
- Most abundant in photosynthetically active tissues
- Present throughout the plant body in various forms
