Question

Flowers that have a single ovule in the ovary and are packed into inflorescence are usually pollinated by

• A. Water
• B. Bee
• C. Wind
• D. Bat

Answer 1

The correct option is C

Wind

The correct option is C.

Explanation of correct answer:

1. Pollination refers to the transfer of pollen grains from the stamens to the ovules.
2. Pollinating agents include insects, birds, water, and wind.
3. The flowers that possess a single ovule and are packed into an inflorescence are pollinated by wind.
4. Pollination by wind is referred to as anemophily. In such flowers, the pollen is lightweight and non-sticky so it can be easily dispersed by wind.

Explanation of incorrect option:

Option A:

1. Water pollination is known as hydrophily and the water pollinated plants are usually aquatic.
2. The pollen is dispersed and floats on the water surface until it comes in contact with the desired flower.

Option B:

1. Pollination by insects such as bees is known as entomophily in which the pollen grains are distributed by bees.
2. When a bee collects nectar from a flower, the pollen from the stamen sticks to its body hairs.
3. When the bee visits a different flower, the pollen is rubbed off onto the stigma.

Option D:

1. Pollination facilitated by bats is known as chiropterophily.
2. Such plants are usually large pale nocturnal flowers and bell-shaped.

Final answer: Flowers that have a single ovule in the ovary and are packed into inflorescence are usually pollinated by wind.
