Structure and Function of Plant Roots Answer Key

1. 
Roots which originate from stems, branches, leaves, or other unusual places on the plant are known as adventitious roots.
2. 
A tap root is usually formed by thin, moderately branching roots growing from the stem.
  1. True
  2. False
3. 
What is the function of plant roots?
  1. to collect sunlight
  2. to absorb nutrients from the soil
  3. to produce flowers for reproduction
  4. to eliminate wastes from the leaves
4. 
Which plant has a taproot system?
  1. carrot
  2. grass
  3. peas
  4. lettuce
5. 
What layer of tissue is just underneath the epidermal layer of a plant root?
  1. cortex
  2. endodermis
  3. root cap
  4. root hairs
6. 
What structure promotes growth and elongation of the plant root?
  1. root hairs
  2. vascular cylinder
  3. apical meristem
  4. Casparian strip
7. 
Where is ground tissue found in a plant root?
  1. within the vascular cylinder
  2. on the outside of the root
  3. inside the root hairs
  4. just underneath the outer layers
8. 
Which structure increases the root's surface area to allow for more water and mineral absorption?
  1. apical meristem
  2. root hair
  3. epidermal tissue
  4. cortex
9. 
What mechanism does the plant root use to bring water into the plant?
  1. osmosis
  2. active transport
  3. binary fission
  4. accumulation
10. 
How does active transport relate to the mechanism plants use to take in minerals from the soil?
  • The root hairs of plant root contain active transport proteins. ATP is used to bring the minerals from the soil into the plant roots because the concentration of them is higher within the root than in the soil. Since there is a higher concentration of minerals within the root, water follows the minerals into the plant through the process of osmosis.
