Parts of a Plant

What is the main function of roots in a plant?

• To store excess water and nutrients

• To produce energy through photosynthesis

• To provide support for the leaves and flowers

• To anchor the plant in the soil and absorb water and nutrients

Name the two main types of roots found in plants.

• Green roots and brown roots

• Round roots and square roots

• Long roots and short roots

• Taproots and fibrous roots

How do taproots differ from fibrous roots?

• Taproots have no main root and only small lateral roots

• Fibrous roots have a main thick root with smaller lateral roots

• Taproots have a main thick root with smaller lateral roots.

• Taproots and fibrous roots are the same

What is the purpose of root hairs?

• Protect the plant from pests and diseases

• Anchor the plant to the ground

• Absorb water and nutrients from the soil

• Store excess water for the plant

Explain the process of root absorption in plants.

• Root absorption is the process by which stems absorb water and nutrients from the soil.

• Root absorption is the process by which roots take in water and nutrients from the soil.

• Root absorption is the process by which leaves take in water and nutrients from the air.

• Root absorption is the process by which roots release water and nutrients into the soil.

What are the different ways in which plants use their roots to obtain nutrients?

• Stem elongation, leaf expansion, and flower development

• Absorption, symbiotic relationships with fungi, and root exudates

• Seed dispersal, pollination, and germination

• Photosynthesis, transpiration, and respiration

Describe the structure of a typical root.

• The structure of a typical root includes bark, pith, and cambium.

• The structure of a typical root includes thorns, tendrils, and spines.

• The structure of a typical root includes leaves, flowers, and stems.

• The structure of a typical root includes the root cap, apical meristem, root hairs, and vascular tissue.

How do roots help prevent soil erosion?

• By binding the soil particles together and creating a stable structure

• By absorbing excess water and reducing the weight of the soil

• By attracting animals that help stabilize the soil

• By releasing chemicals that repel water and prevent erosion

What is the role of roots in the process of photosynthesis?

• Absorb water and minerals from the soil

• Help the plant to stand upright

• Produce oxygen for the plant

• Store energy for the plant

Explain the relationship between roots and mycorrhizal fungi.

• Mycorrhizal fungi form a symbiotic relationship with plant roots.

• Mycorrhizal fungi compete with plant roots for nutrients.

• Mycorrhizal fungi have no interaction with plant roots.

• Mycorrhizal fungi are harmful to plant roots.
