Root systems are classified as fibrous root systems and taproot systems.
slamgirl [31]

Answer:

<u>B)  the branching pattern of the roots</u>

Explanation:

Plant roots function as anchors,  food storage and aid in the uptake of water and minerals- other modifications include gas exchange and chemical signaling.

Root systems are mainly classified as taproots, usually found in dicots or fibrous roots found in monocots - some plants are a varying combination of the two systems.  While tap roots consist of a larger, vertical main root surrounded by smaller lateral roots, fibrous roots are typically a dense network of roots that grow near the surface of the soil.

Taproots are thought to be more common in plants inhabiting regions experiencing water scarcity, while fibrous roots are thought to grow in more lush, water-abundant regions.

Examples of these roots systems include...

  • taproots: dandelions, carrots, turnips
  • fibrous roots: grasses, corn

Which of the following is not associated with the large absorptive surface of the small intestine?
antiseptic1488 [7]

The circular folds slow the passage of the partly digested food along the intestines, and afford an increased surface for absorption. They are covered with small finger-like projections called villi (singular, villus). Each villus, in turn, is covered with microvilli.

While rugae is only evident when an organ or tissue deflares or relaxes. The rugae unfolds for increase in volume . Plicae remains folded in the intestinal walls.

Rugae is not associated with the large absorptive surfaces in the small intestine.
