Study Notes
Fleshy Tap Roots
- Modified for food storage, resulting in swollen primary roots.
- Serve as a food reservoir for the plant.
Types of Fleshy Tap Roots
-
Conical Roots
- Broad at the base, tapering towards the apex.
- Secondary roots distributed throughout the swollen region.
-
Fusiform Roots
- Swollen in the middle, tapering at both ends.
- Characterized by a spindle-like shape.
-
Napiform Roots
- Thick at the base, forming a spherical shape, thinning towards the bottom.
- Food is primarily stored in the upper swollen section.
-
Tuberous Tap Roots
- No specific shape; these roots are fleshy and irregular.
- Function primarily to store reserved food.
-
Modulated Roots
- Secondary, tertiary, or primary roots develop small nodule-like swellings.
- Root nodules are home to nitrogen-fixing bacteria that convert atmospheric nitrogen into organic nitrogen compounds.
- Play a vital role in enhancing soil fertility.
-
Respiratory Roots
- Found in mangroves or coastal swamp plants.
- Emerge vertically from soil/water, equipped with lenticels for gas exchange.
- Adapted to facilitate respiration in waterlogged conditions.
