Explanation:

• Here the sentence is in passive voice.
• Voice is of two types - active voice and passive voice.
• When the transformation occurs from active to passive voice then certain rules must be followed. The rules are different for different tens.
• Here the tens can be present or past indefinite.
• Voice change for present indefinite tens:

        Passive voice- Object + is/are + past participle form of verb + by + subject.

• Voice change for past indefinite tens:

        Active voice- Subject + past form of verb + object

        Passive voice- Object + was/were + past participle form of verb + by + subject.

1) If the active voice is present indefinite tens then the sentence will be:  the flowers are kept in a vase .
