Plants absorb carbon dioxide from the atmosphere and convert it into usable energy via photosynthesis. In what sequential order does carbon move and transform within a plant, starting from initial absorption to its distribution as sugar?
- 1Carbon dioxide enters the leaf from the surrounding air through microscopic pores called stomata.
- 2The gas diffuses through the internal air spaces into the chloroplasts of leaf cells.
- 3Chemical energy generated from sunlight fixes the carbon atoms into glucose molecules.
- 4The synthesized glucose is transported through phloem tissue to nourish other plant parts.
Answer
Carbon dioxide enters through stomata → diffuses into chloroplasts → is converted into glucose molecules → transported through phloem tissue.
The correct sequence begins with the intake of gaseous carbon dioxide through leaf stomata, followed by its diffusion into the chloroplasts where photosynthesis occurs. Solar energy converts this carbon into glucose, which is subsequently transported throughout the organism via the phloem vascular tissue.
