Study Notes
Fleshy Tap Roots
- Modified roots specifically developed for food storage.
- The primary root enlarges to store nutrients, resulting in a swollen appearance.
Types of Fleshy Tap Roots
-
Conical Roots:
- Broad at the base and gradually tapering towards the apex.
- Secondary roots are distributed along the swollen portion.
-
Fusiform Roots:
- Swollen in the center, tapering towards both ends.
- Characteristic spindle shape due to its structure.
-
Napiform Roots:
- Thickest at the base and spherical in shape.
- Tapers downwards, with food storage concentrated in the upper swollen part.
Tuberous Tap Roots
- Lack a specific shape and are categorized as tuberous.
- Primarily serve the purpose of reserving food.
Modulated Roots
- Secondary, tertiary, or sometimes primary roots develop small nodule-like swellings.
- Root nodules host nitrogen-fixing bacteria that convert atmospheric nitrogen into organic nitrogen compounds.
- Contribute to enhanced soil fertility through the process of nitrogen fixation.
Respiratory Roots
- Found in plants adapted to mangroves or swampy areas near coastlines.
- Emerge vertically from soil or water to facilitate gas exchange.
- Possess lenticels—small pores that allow for the exchange of gases between the root and the atmosphere.
