The correct option is
C. produce suckers.
Detailed Explanation:
- Understanding the Plants:
- Bananas and plantains are both members of the genus Musa. They are known for their large, herbaceous plants that produce edible fruits.
-
Pineapples belong to the genus Ananas and are a type of bromeliad. They are also known for their unique growth habits and fruit structure.
-
What are Suckers?:
-
Suckers are shoots that grow from the base of a plant or from its roots. In the case of bananas and plantains, these suckers can develop into new plants. This is a form of vegetative reproduction, allowing the plant to spread and propagate without the need for seeds.
-
Why Option C is Correct:
- Both bananas and plantains produce suckers that can be used to propagate new plants. This is a common method of cultivation for these species, as it allows for the rapid establishment of new plants that are genetically identical to the parent plant.
- While pineapples do not produce suckers in the same way, they can produce offshoots or "pups" that can be planted to grow new pineapple plants. Thus, the grouping of these three fruits based on their ability to produce suckers is valid, particularly for bananas and plantains.
Why the Other Options are Incorrect:
- Option A: Produce small seeds:
-
This option is misleading. While bananas and plantains do have seeds, they are typically very small and not functional in cultivated varieties, which are often seedless. Pineapples also have seeds, but they are not a defining characteristic that groups these fruits together. Therefore, this option does not accurately represent a common feature among the three.
-
Option B: Are multiple fruit:
-
A multiple fruit is formed from a cluster of flowers (inflorescence) that fuse together to form a single fruit. Pineapples are indeed classified as multiple fruits, but bananas and plantains are not. They are classified as simple fruits that develop from a single ovary. Thus, this option is incorrect as it does not apply to all three fruits.
-
Option D: Have runners:
- Runners are horizontal stems that grow along the ground and can produce new plants at nodes. This is characteristic of some plants like strawberries, but not of bananas, plantains, or pineapples. Bananas and plantains produce suckers, while pineapples do not produce runners at all. Therefore, this option is also incorrect.
Summary:
- Suckers are a common method of vegetative reproduction for bananas and plantains.
- Pineapples can produce offshoots, but they do not produce suckers in the same way.
- Seeds and multiple fruits do not accurately describe a common feature among all three fruits.
- Runners are not a characteristic of any of these plants.
Revision Summary:
- Bananas and plantains produce suckers for vegetative reproduction.
- Pineapples can produce offshoots but not suckers.
- The term "multiple fruit" applies only to pineapples, not to bananas or plantains.
- Understanding the reproductive methods of these plants is key to identifying their similarities and differences.
