1. What is parthenocarpy?
A.
Development of fruit without fertilization
B.
Development of seeds without pollination
C.
Development of roots from leaves
D.
Development of flowers without sunlight
Correct Answer:
Development of fruit without fertilization
Explanation:
Parthenocarpy is the formation and development of fruits without fertilization.
2. Parthenocarpic fruits are generally:
A.
Seedless
B.
Very leafy
C.
Always poisonous
D.
Unable to grow
Correct Answer:
Seedless
Explanation:
Since fertilization does not occur in parthenocarpy, seeds usually do not develop inside the fruit.
3. Which process is specifically produced in parthenocarpy?
A.
Fruit formation without seed formation
B.
Seed formation without fruit formation
C.
Leaf formation without stems
D.
Root formation without water
Correct Answer:
Fruit formation without seed formation
Explanation:
Parthenocarpy produces a fruit even when fertilization and normal seed formation are absent.
4. What is a common agricultural application of parthenocarpy?
A.
Production of seedless fruits
B.
Production of thorny stems
C.
Prevention of leaf growth
D.
Reduction of root development
Correct Answer:
Production of seedless fruits
Explanation:
Parthenocarpy is useful in agriculture because it allows the production of fruits without seeds.
5. Which type of fruit can result from parthenocarpy?
A.
A fruit formed without fertilization
B.
A fruit formed only after seed germination
C.
A fruit formed from a root
D.
A fruit formed only after leaf fall
Correct Answer:
A fruit formed without fertilization
Explanation:
A parthenocarpic fruit develops from the ovary without the fusion of male and female gametes.
6. Why are parthenocarpic fruits often preferred by consumers?
A.
They usually contain no seeds
B.
They always have green leaves attached
C.
They cannot ripen
D.
They contain extra roots
Correct Answer:
They usually contain no seeds

7. In parthenocarpy, fruit development occurs in the absence of:
A.
Fertilization
B.
Water absorption
C.
Respiration
D.
Cell division
Correct Answer:
Fertilization
Explanation:
The defining feature of parthenocarpy is fruit development without fertilization.
8. A fruit produced through parthenocarpy is best described as:
A.
A seedless fruit
B.
A rootless plant
C.
A flowerless seed
D.
A non-living structure

It stops all fruit development
D.
It changes fruits into roots
Correct Answer:
It produces fruits without fertilization

10. The main benefit of inducing parthenocarpy in crop plants is:
A.
Obtaining seedless fruits
B.
Obtaining seed-filled leaves
C.
Increasing the number of roots on fruits
D.
Preventing all flowers from opening
Correct Answer:
