B.
They cause immediate wilting
C.
They stop water absorption
D.
They remove the flower petals
Correct Answer:
They delay flower senescence
Explanation:
Cytokinins delay senescence, or aging, in cut flowers and help them remain fresh for a longer time.
2. Why are cytokinins useful in the preservation of cut flowers?
A.
They extend the freshness of the flowers
B.
They change flowers into fruits
C.
They prevent the formation of roots
D.
They reduce the size of flower petals
Correct Answer:
They extend the freshness of the flowers
Explanation:
Cytokinins help preserve cut flowers by slowing aging and keeping them fresh for a longer period.
3. Which process is delayed by cytokinins in cut flowers?
A.
Senescence
B.
Pollination
C.
Seed germination
D.
Fruit ripening
Correct Answer:
Senescence
Explanation:
Cytokinins delay senescence in cut flowers, which helps maintain their appearance after they are cut.
4. A florist may use a cytokinin treatment mainly to keep cut flowers looking fresh for a longer time. This is an example of which use of cytokinins?
A.
Cut flower preservation
B.
Seed dispersal
C.
Fruit formation
D.
Root pruning
Correct Answer:
Cut flower preservation
Explanation:
Using cytokinins to slow aging and maintain the freshness of cut flowers is called cut flower preservation.
5. Cytokinins help preserved cut flowers mainly by maintaining which characteristic?
A.
Fresh appearance
B.
Seed number
C.
Root length
D.
Fruit sweetness
Correct Answer:
Fresh appearance
Explanation:
By delaying senescence, cytokinins help cut flowers retain a fresh appearance after being separated from the plant.
6. What would most likely happen when a suitable cytokinin treatment is applied to a cut flower?
A.
The flower remains fresh longer
B.
The flower wilts instantly
C.
The flower produces underground stems
D.
The flower loses all its petals immediately
Correct Answer:
The flower remains fresh longer

7. Which plant hormone is associated with delaying senescence in cut flowers?
A.
Cytokinin
B.
Auxin
C.
Gibberellin
D.
Abscisic acid
Correct Answer:
Cytokinin
Explanation:
Cytokinins are known for delaying senescence and are therefore used to preserve cut flowers.
8. The preservation of cut flowers with cytokinins is based on their ability to slow down which process?
A.
Aging
B.
Pollination
C.
Seed dispersal
D.
Root branching
Correct Answer:
Aging
Explanation:
Cytokinins slow the aging process, also called senescence, in cut flowers.
9. Which result is expected from delaying senescence in a cut flower?
A.
Longer vase life
B.
Earlier wilting
C.
Faster seed production
D.
Immediate fruit development
Correct Answer:
Longer vase life
Explanation:
When senescence is delayed, the cut flower stays usable and attractive in a vase for a longer period.
10. Cytokinins are added to some cut-flower treatments primarily to prevent the flowers from becoming old too quickly. What term describes this benefit?
A.
Delay of senescence
B.
Promotion of dormancy
C.
Induction of germination
D.
Stimulation of fruit ripening
Correct Answer:
