COMPARISON OF RETICULATE VENATION AND PARALLEL VENATION

1. Fibrous Roots

Characteristics:

  • Fibrous roots consist of many thin roots that are roughly the same size.
  • These roots grow from the base of the stem and there is no single dominant main root.
  • The roots spread out widely and mostly grow sideways near the soil surface.
  • They have many short, fine root branches.
  • Usually found close to the surface of the soil.

Functions:

  • Absorb water and nutrients from the upper soil layers.
  • Help stabilize the soil and prevent erosion.
  • Allow the plant to quickly absorb small amounts of water.

Examples of Plants:

  • Grass
  • Rice
  • Corn (Maize)
  • Oil palm

Advantages:

  • Prevents soil erosion due to wide root spread.
  • Quickly absorbs water after rainfall.

2. Taproots

Characteristics:

  • Taproots have one large, thick main root that grows straight down.
  • Smaller lateral roots branch out from this main root vertically or horizontally.
  • The main root is thicker and more dominant than its branches.
  • Taproots can grow very deep into the soil.

Functions:

  • Absorb water from deeper soil layers.
  • Support the plant firmly in the ground.
  • Store food and nutrients in the main root (storage root).

Examples of Plants:

  • Beans
  • Carrots
  • Mango trees
  • Durian trees

Advantages:

  • Able to access water deep in the soil during dry seasons.
  • Storage roots help the plant survive in poor nutrient conditions.
