Exploring Plant Roots

What is the primary function of roots in plants?

• The primary function of roots in plants is to anchor the plant and absorb water and nutrients.

• To facilitate gas exchange with the atmosphere

• To store energy for photosynthesis

• To produce flowers and seeds

How do roots help in anchoring a plant?

• Roots help anchor a plant by gripping the soil and providing stability.

• Roots are primarily for photosynthesis.

• Roots produce flowers for reproduction.

• Roots absorb water and nutrients only.

What type of roots grow directly from the stem?

• Adventitious roots

• Fibrous roots

• Tap roots

• Bulbous roots

What is the role of root hairs in plants?

• Root hairs store energy for the plant.

• Root hairs help in the absorption of water and nutrients from the soil.

• Root hairs are responsible for photosynthesis.

• Root hairs protect the roots from pests.

How do roots contribute to nutrient absorption?

• Roots contribute to nutrient absorption by increasing surface area for uptake, releasing exudates, and forming symbiotic relationships.

• Roots are mainly responsible for photosynthesis in plants.

• Roots primarily store energy for the plant.

• Roots only absorb water and do not play a role in nutrient uptake.

What is the difference between taproots and fibrous roots?

• Taproots are deep and thick, while fibrous roots are shallow and thin.

• Taproots are shallow and thin, while fibrous roots are deep and thick.

• Taproots grow in clusters, while fibrous roots grow individually.

• Taproots are found only in aquatic plants, while fibrous roots are found in desert plants.

How do roots help in water absorption?

• Roots absorb water through photosynthesis.

• Roots store water for later use.

• Roots help in water absorption by increasing surface area and creating a concentration gradient for osmosis.

• Roots help in water absorption by producing chlorophyll.

What is the term for the symbiotic relationship between roots and fungi?

• mycorrhiza

• mycoflora

• root network

• symbiosis

How do roots respond to gravity?

• Roots grow upward in response to gravity.

• Roots do not respond to gravity at all.

• Roots grow sideways in response to gravity.

• Roots grow downward in response to gravity.

Why are roots important for soil health?

• Roots are primarily for anchoring plants and have no other benefits.

• Roots are essential for improving soil structure, preventing erosion, and enhancing nutrient cycling.

• Roots only absorb water and do not affect soil health.

• Roots can harm soil by competing with microorganisms for nutrients.
